Electric-Drive vs. Hydraulic-Drive Scissor Lifts

Buying a scissor lift should be straightforward. You choose a platform height, a load capacity, and a power source—and you order. But somewhere between the product page and the purchase order, most buyers encounter two terms that turn a simple decision into a confusing one: electric and hydraulic.

The problem is not the terminology itself. The problem is that almost everyone in the industry uses these words loosely, interchangeably, and often incorrectly. Sales representatives, rental catalogues, and even some technical datasheets treat the two as complete opposites, as though one machine is electric in every sense and the other is hydraulic in every sense. That framing is wrong—and it has real consequences for buyers who base their decisions on it. For a broader look at how access equipment terminology has evolved over the decades, see our article on scissor lift and manlift industry terminology.

This article will correct that misunderstanding first, before doing anything else. Once you know what electric and hydraulic actually refer to inside a modern scissor lift, the comparison between the two drivetrain technologies becomes far clearer, and the decision about which one to buy becomes far easier.

By the end of this guide, you will understand exactly how each system works, where the measurable differences lie, and why the access equipment industry has been gradually migrating toward electric-drive technology. If you would prefer to explore Galen’s full range of electric scissor lifts directly, the ES Series product pages include detailed specifications and application guidance.

The Biggest Misconception About Scissor Lifts

When most people hear ‘electric scissor lift,’ they picture a machine that runs on electricity—full stop. And when they hear ‘hydraulic scissor lift,’ they imagine a machine that runs on oil pressure instead. This mental model feels intuitive, but it is almost entirely wrong, and it leads buyers to compare machines on grounds that do not actually exist.

Here is the truth: in virtually every scissor lift currently on the market, lifting is hydraulic. The scissor mechanism that raises and lowers the platform is powered by a hydraulic cylinder. Steering is hydraulic. The braking system is hydraulic. None of that changes regardless of whether the machine is described as electric or hydraulic. Both types of machine carry a battery, both use hydraulic fluid, and both depend on a pump to pressurize that fluid so the platform can rise.

What actually differs between an ‘electric’ scissor lift and a ‘hydraulic’ scissor lift is only the traction system—the mechanism that drives the wheels and moves the machine across the floor. In a hydraulic-drive machine, the traction motor is a hydraulic motor: the pump sends pressurized oil to a motor mounted at the wheel, and that motor turns the axle. In an electric-drive machine, the traction motor is an electric motor: the battery sends current through a controller to a brushless motor, which drives the wheel through a compact gearbox.

That single difference—hydraulic motor versus electric motor at the wheel—is the entire distinction. It is a meaningful distinction, with real implications for efficiency, maintenance, traction control, and operator experience. But it is a far narrower distinction than most buyers realize, and understanding its precise scope is the foundation for everything that follows.

FIGURE 1 — HYDRAULIC-DRIVE ARCHITECTURE

In a hydraulic-drive scissor lift, the battery powers an electric motor that drives a hydraulic pump. Pressurized oil travels through hoses and valves to a hydraulic motor at each driven wheel, converting fluid pressure back into rotational force. Every energy conversion in this chain carries an efficiency loss.

FIGURE 2 — ELECTRIC-DRIVE ARCHITECTURE

In an electric-drive scissor lift, battery current flows directly to a closed-loop controller, which regulates a brushless electric motor. The motor drives the wheel through a compact planetary gearbox—no hydraulic fluid is involved in the traction circuit at any point. Fewer conversion stages means less energy lost as heat.

How Does a Hydraulic-Motor Drive Scissor Lift Work?

Understanding the hydraulic-drive system begins with the battery. Like all modern scissor lifts, a hydraulic-drive machine runs on a rechargeable battery pack—typically lead-acid or lithium-ion. The battery’s job is to supply electrical energy to an electric motor that, in turn, drives a hydraulic pump. At this point in the chain, the machine is still operating electrically.

The pump is the heart of the traction system. It draws hydraulic oil from a reservoir and pressurizes it, typically to operating pressures between 150 and 300 bar depending on the design and load conditions. That pressurized oil then travels through a network of hoses, fittings, control valves, and flow dividers before it reaches the hydraulic traction motors mounted at the driven wheels.

At each wheel, a hydraulic motor receives the pressurized oil and converts it back into rotational motion. The motor shaft connects to the wheel hub, either directly or through a simple reduction stage, and the wheel turns. When the operator releases the travel control, a valve closes, oil flow stops, and the motor—and therefore the wheel—ceases to rotate.

The elegance of this arrangement is its mechanical simplicity at the wheel end. A hydraulic motor has very few moving parts and requires no electronics at the point of drive. The control logic sits entirely in the valve block, which is a mature and well-understood technology with decades of development behind it.

The limitation of the system is thermodynamic. Every time energy changes form, some of it is lost as heat. In a hydraulic-drive traction circuit, energy changes form multiple times: electrical energy in the battery becomes mechanical rotation in the pump motor, which becomes hydraulic pressure in the oil, which becomes mechanical rotation again at the traction motor. Hose friction, valve pressure drops, and motor volumetric inefficiency all extract a toll. The cumulative result is a traction system that, under typical operating conditions, delivers somewhere between 40 and 60 percent of the battery’s stored energy to the wheels as useful motion. Our scissor lift maintenance checklist covers the routine inspection points—hoses, seals, fluid levels, and filters—that keep a hydraulic-drive system performing within those bounds over time.

There is also the question of flow balance. When a machine has two driven wheels, a hydraulic system must divide flow equally between the two traction motors to prevent one wheel from outrunning the other on a straight line. This is typically done with a flow divider valve. Flow dividers work reasonably well under steady-state conditions, but they struggle when one wheel encounters a different surface than the other—a topic we will return to when discussing traction control.

How Does an Electric-Motor Drive Scissor Lift Work?

In an electric-drive scissor lift, the traction circuit does not involve hydraulic fluid at any point. The battery supplies direct current to a solid-state electronic controller—typically a modern MOSFET-based inverter—which is responsible for managing every aspect of the motor’s behaviour. The Galen ES Series implements this architecture across its full range, from the compact ES0808 to the high-reach ES1212.

The controller is the intelligence of the system. It reads a continuous stream of data from shaft encoders mounted on each motor, measuring rotational speed and angular position at hundreds of times per second. It compares the actual speed and torque output against the desired values set by the operator through the travel control, and it adjusts the current supplied to the motor accordingly. This is closed-loop control, and it is what separates electric-drive traction from its hydraulic counterpart.

The motor itself is typically a brushless permanent-magnet DC motor or—in higher-performance designs such as the ES1012 and ES1212—a Permanent Magnet Synchronous Motor (PMSM), which delivers superior torque density and efficiency across the full operating speed range. The motor connects to the wheel through a compact planetary gearbox, which steps down the motor’s high rotational speed to the lower speed required at the wheel while multiplying torque proportionally.

Because the controller governs torque directly—rather than inferring it from hydraulic pressure—it can respond to changing conditions in milliseconds. If the operator requests a specific speed and the encoder reports that the wheel is not reaching it, the controller immediately increases current to the motor. If the wheel suddenly loses traction and begins to spin faster than the machine is actually moving, the controller detects the discrepancy and reduces torque to bring the wheel back under control.

The energy path in this system is remarkably direct: battery current flows through the controller to the motor, which converts it to torque at the gearbox output flange. The total number of energy conversions is two—electrical to electromagnetic, electromagnetic to mechanical—compared with four or more in a hydraulic-drive circuit. That reduction in conversion steps is the primary reason electric-drive systems are substantially more energy-efficient.

Electric-Drive vs. Hydraulic-Drive: Side-by-Side Comparison

Why Electric-Drive Systems Consume Less Energy

Consider a maintenance technician working inside a large distribution warehouse for an entire eight-hour shift. The job involves moving between racking aisles repeatedly throughout the day—short bursts of travel separated by periods of stationary work at height. Every time the machine travels between locations, the traction system draws current from the battery. Although a hydraulic-drive machine and an electric-drive machine sitting side by side may appear completely identical from the outside, the difference in current consumption during those travel phases is dramatic.

A hydraulic-drive scissor lift traveling at normal operating speed will typically draw approximately 30 amperes from the battery to sustain traction. That current is consumed first by the electric pump motor, then dissipated through pressure losses in the hose circuit, valve restrictions, and the hydraulic traction motors themselves. The wheel receives only a fraction of the energy that left the battery.

An electric-drive machine performing the same task—same speed, same payload, same floor surface—will draw approximately 10 amperes under equivalent conditions. The saving comes directly from the elimination of the intermediate hydraulic conversion stage. The controller sends current to the motor, the motor turns the wheel, and most of what left the battery arrives at the axle as useful torque.

The implications of a three-to-one reduction in traction current compound quickly over the course of a working day. Consider a shift during which the machine travels for a total of two hours. A hydraulic-drive system drawing 30 amperes for those two hours consumes 60 ampere-hours of battery capacity on traction alone. An electric-drive system drawing 10 amperes for the same two hours consumes only 20 ampere-hours. That 40 ampere-hour difference represents a very large portion of a typical scissor lift battery’s usable capacity.

Therefore, an electric-drive machine delivers meaningfully longer runtime between charges, requires charging intervention less frequently across a working week, places fewer deep-discharge cycles on the battery over its service life, and accumulates lower electricity costs per hour of operation. Galen’s ES Series electric scissor lifts are available with lithium-ion battery options that extend these advantages further—faster charging, no memory effect, and consistent voltage delivery throughout the discharge cycle.

Cleaner Machines Mean Lower Maintenance Costs

A hydraulic-drive scissor lift carries a hydraulic oil circuit that touches every part of the traction system. That circuit requires periodic oil changes, regular inspection and replacement of hydraulic hoses, the monitoring and replacement of seals, and filter changes to maintain oil cleanliness. For a full breakdown of what a structured maintenance programme looks like in practice, our scissor lift maintenance checklist covers each inspection point in detail.

If the system develops a slow leak—as hydraulic systems periodically do—it requires a cleanup of whatever surface the machine was operating on at the time. In a warehouse environment, hydraulic oil contamination is an inconvenience and a housekeeping cost. In certain industries, it is something far more serious.

Food processing facilities, pharmaceutical manufacturing plants, electronics assembly cleanrooms, and medical device factories operate under strict contamination control regimes. The presence of mineral hydraulic oil—even in trace quantities from a minor seep around a hose fitting—can trigger production shutdowns, failed regulatory inspections, product recalls, and significant financial penalties. Galen’s commitment to clean, low-maintenance engineering is reflected throughout our quality policy, which covers compliance with CE marking, EN 280 standards, and our continuous improvement approach to reducing total cost of ownership.

An electric-drive scissor lift eliminates the traction hydraulic circuit entirely. There are no traction hoses, no traction oil, no traction seals, and no traction filters. The motors are sealed units with long service intervals. The gearboxes are grease-lubricated and typically specified for many thousands of hours between services. The controllers are solid-state electronics with no moving parts and no consumable media. For machines that do require service—whether routine or following an incident—Galen’s after-sale service programme and machine reconditioning service are available to support fleet operators at every stage of the machine’s working life.

Closed-Loop Motor Control: The Biggest Advantage Few People Talk About

Energy efficiency and maintenance simplicity are the advantages of electric drive that most manufacturers mention. There is a third advantage that is rarely explained in any depth, yet it is arguably the most important from a practical operating standpoint: the traction control capability that closed-loop motor control enables.

In an electric-drive system, each wheel motor has a shaft encoder—a sensor that reports the motor’s rotational speed and position to the controller thousands of times per second. The controller uses this information to regulate torque with a precision that no hydraulic system can approach. It knows, at all times, exactly how fast each wheel is turning and exactly how much torque it is applying. If there is a discrepancy between what the operator has requested and what the encoder reports, the controller corrects it within milliseconds.

Imagine driving a scissor lift across a warehouse floor and onto a loading ramp. The ramp surface is slightly damp. The left wheel meets a dry patch, and the right wheel meets a slippery one. In a hydraulic-drive machine, the flow divider attempts to supply equal oil flow to both traction motors, but it cannot respond dynamically to a sudden change in wheel traction. The right wheel—the one on the slippery surface—will spin freely if the hydraulic motor receives more flow than the traction available can absorb. The machine yaws to the right, the operator corrects with steering, and the momentary loss of control is managed manually.

In an electric-drive machine, the encoder on the right motor immediately detects that the wheel is rotating faster than the machine’s actual velocity implies. The controller reduces torque to that wheel in microseconds, before the slip develops into a visible yaw. The left wheel continues to pull normally. The machine tracks straight, the operator notices nothing unusual, and the crossing of the ramp boundary is seamless. This is the same principle that underlies electronic stability control and ABS braking in modern vehicles—and it works for the same reason: real-time feedback from wheel-speed sensors feeding a fast digital controller. The ES1012 and ES1212, with their PMSM drive systems and European-brand control electronics, implement this capability as standard—not as an optional upgrade.

This capability matters whenever the machine operates on surfaces that vary in grip—painted warehouse floors, polished concrete, wet ramps, or the junction between different flooring materials. It matters when one wheel crosses a threshold strip or a floor drain. And it matters when the machine is navigating in tight spaces, where a momentary yaw correction could bring the platform dangerously close to a rack or a doorframe.

Why Operators Prefer Electric Drive

The engineering advantages of electric drive—efficiency, cleanliness, traction control—are straightforward to quantify. What is harder to quantify, but equally real, is the difference in the daily experience of the people who operate these machines for eight hours at a time. Galen’s operator training programme consistently finds that operators transitioning from hydraulic-drive to electric-drive machines report a measurable reduction in the attention and correction effort required during travel.

Electric-drive machines accelerate smoothly. When an operator pushes the travel control forward, the controller ramps torque up gradually, producing a progressive, predictable onset of motion. There is no hydraulic surge, no initial delay while the pump builds pressure, and no sudden lurch if the control is pushed too quickly. The machine responds proportionally to input, which makes precise positioning—nudging the platform into exactly the right location beneath an overhead fixture—something that skilled operators achieve almost effortlessly.

Braking is equally smooth. Releasing the travel control triggers regenerative braking on most electric-drive systems: the motor becomes a generator, slowing the machine progressively while returning a small amount of energy to the battery. The deceleration is smooth, linear, and predictable. Operators do not need to brace against a sudden stop or anticipate an unpredictable deceleration profile when approaching a wall or a rack.

Over a full shift, these differences in smoothness and predictability reduce operator fatigue significantly. Driving a machine that responds exactly as expected, every time, is less mentally demanding than managing one whose responses vary with hydraulic pressure, oil temperature, and valve condition. Reduced fatigue means better concentration, fewer positioning errors, and a lower likelihood of contact incidents with the surrounding environment.

Which Industries Benefit Most?

Electric-drive scissor lifts deliver advantages that are relevant across a wide range of commercial and industrial settings. The following sectors see the most consistent and significant benefits:

• Warehouses and Distribution Centres — High-frequency travel between racking aisles amplifies the runtime and energy efficiency advantages of electric drive, while the clean drivetrain eliminates contamination risk in facilities handling sensitive goods. The compact ES0808 and the ES0507 are particularly well-suited to narrow-aisle warehouse environments.
• Manufacturing Facilities — Complex floor environments with varied surface materials, floor transitions, and tight aisle geometries benefit directly from closed-loop traction control and the precise operator response that electric drive enables.
• Automotive Assembly Plants — Continuous operation across long shifts, combined with strict floor cleanliness standards, makes the low-maintenance, oil-free traction system particularly valuable.
• Logistics and Third-Party Fulfilment — Fleet operators managing large numbers of machines across multiple sites benefit from reduced maintenance overhead and extended battery intervals. Galen’s reconditioning servicesupports fleet lifecycle management for operators scaling their equipment base.
• Aircraft Maintenance Hangars — The combination of smooth, precise travel control and zero risk of hydraulic oil contamination on aircraft surfaces makes electric drive the preferred choice in MRO environments. The ES1012and ES1212 provide the working height required for most commercial aircraft maintenance tasks.
• Retail Distribution — Light-duty, high-frequency use with operators of varying experience levels rewards the smooth, forgiving acceleration and braking characteristics of electric-drive systems.
• Food Processing and Cold Storage — Strict contamination control requirements and challenging floor conditions in refrigerated environments make the oil-free traction circuit and superior traction management of electric drive essential rather than merely preferable.
• Pharmaceutical and Cleanroom Manufacturing — Regulatory compliance requirements around contamination make the elimination of traction hydraulic oil a practical necessity. Galen’s quality policy and CE certification provide the compliance documentation that procurement teams in regulated industries require.

Frequently Asked Questions

Is an electric scissor lift completely electric?

No. Despite the name, an electric scissor lift is not fully electric in its operation. The lifting mechanism—the hydraulic cylinder that raises and lowers the platform—remains hydraulic in both electric-drive and hydraulic-drive machines. What the ‘electric’ label refers to is the traction drive: the system that moves the machine across the floor. For a detailed explanation of how access equipment terminology has evolved, see our article on scissor lift and manlift industry terminology.

Do electric scissor lifts still use hydraulic fluid?

Yes. Every scissor lift on the market uses hydraulic fluid for lifting and, in most cases, for steering. The distinction between electric-drive and hydraulic-drive machines concerns only the traction circuit. An electric-drive machine does not have hydraulic fluid in its traction system—there are no traction hoses, traction motors, or traction flow dividers—but it still carries hydraulic fluid for everything related to platform elevation.

Which type consumes less battery power during operation?

Electric-drive machines consume significantly less battery power during travel—typically drawing around 10 amperes versus 30 amperes for a hydraulic-drive machine performing the same task. This difference arises from the multiple energy conversions required in a hydraulic traction circuit. All Galen ES Series models are electric-drive and are available with lithium-ion battery options for maximum runtime and fastest recharge cycles.

Which is easier to maintain?

Electric-drive machines are considerably easier to maintain. A hydraulic-drive traction circuit requires oil changes, hose inspections, seal checks, and filter replacements. An electric-drive traction system has no fluid to change and no seals to replace in the traction circuit. Our scissor lift maintenance checklist details the service intervals and inspection points for electric scissor lifts, and our after-sale service team is available for scheduled or corrective maintenance support.

Which is better for indoor use?

Electric-drive machines are generally the superior choice for indoor environments—longer runtime, no contamination risk, and smooth traction control for precise navigation in confined spaces. The ES0808 and ES0507 are specifically designed for tight indoor environments, with compact footprints and non-marking tyre options available for sensitive floor surfaces.

Which offers better traction on difficult surfaces?

Electric-drive machines offer substantially better traction control on variable surfaces. Because each motor’s speed and torque are regulated individually by a closed-loop controller using encoder feedback, the system can detect and correct wheel slip in real time. The ES1012 and ES1212, with PMSM drive and European control systems, deliver particularly refined traction response on the mixed or challenging surfaces common in industrial and logistics environments.

Why are modern manufacturers switching to electric drive?

The shift reflects a convergence of factors: improvements in brushless motor efficiency, advances in solid-state controller design, reductions in permanent magnet costs, and accumulated operator experience demonstrating the practical advantages of electric traction. Galen recognized this direction early—our R&D and engineering philosophy has been oriented toward electric-drive architecture from the outset, rather than retrofitting electric components onto hydraulic platforms. Follow our news and announcements page for updates on new model launches and technology developments.

How do I choose between the Galen ES models?

The choice depends primarily on required working height, platform size, and application environment. The ES0507 and ES0808 serve compact indoor applications. The ES1012 — recently launched with PMSM drive and single-cylinder lifting technology — targets mid-height warehouse and facility maintenance work. The ES1212 provides the highest reach in the range for demanding overhead installations and industrial maintenance. Contact our sales team for a specification-matched recommendation.

Conclusion

Over the past decade, the access equipment industry has gradually shifted toward electric-drive technology—not because it is fashionable, but because it delivers measurable improvements in efficiency, reliability, operating costs, and operator experience. The evidence is consistent across fleet data, maintenance records, and the direct testimony of operators who have worked with both systems. When the comparison is made on a like-for-like basis, under real working conditions, electric drive wins on every dimension that matters to the people and organisations that depend on this equipment daily. For those who want to go further, Galen’s blog and news section publishes ongoing technical content on scissor lift engineering, application guidance, and industry developments.

Understanding why requires looking past the labels. Both machine types carry batteries. Both use hydraulic systems for lifting. The distinction is narrower than the marketing language suggests, but it is also more consequential than most buyers appreciate. It comes down to what happens at the wheel: a cascade of hydraulic conversions, each extracting its toll in heat and pressure loss, versus a direct electrical path from battery to motor to gearbox, governed at every instant by a closed-loop controller that knows exactly what the wheel is doing and responds faster than any valve or human input can match.

At Galen Equipment, we recognized this transition long before it became the industry standard. From the earliest stages of our research and development, our engineering efforts focused exclusively on electric-motor drive systems. Rather than adapting an existing hydraulic platform—preserving legacy architecture while adding electric components around the edges—we designed our machines around the advantages of electric drive from the very first drawing. Every subsystem, every component specification, and every software parameter was chosen to extract the maximum benefit from direct electric traction: the efficiency, the cleanliness, the traction control, and the operator experience that the technology makes possible when it is implemented without compromise.

The result is a range of machines—the ES0507, ES0808, ES1012, and ES1212—built for the environments, the demands, and the expectations of modern industrial operation. Not adapted to them. Built for them. If you are ready to explore which model is right for your application, our team is available through the contact page.
