Scissor Lift Steering Cylinder
EP-HCYY11112004 · Bore Φ40mm · 20 MPa · 2.8 kg

The compact steering actuator on self-propelled scissor lifts. At just 2.8 kg and 400 mm installation distance, this cylinder steers the drive wheels for precise positioning of the platform — manoeuvring around columns, walls, and equipment on crowded job sites. Mounted on the steer axle, it converts hydraulic pressure from the operator's joystick into wheel angle.

How the Steering Cylinder Positions the Scissor Lift

Self-propelled scissor lift with steering mechanism

Self-propelled scissor lifts drive and steer under their own power — the operator controls movement from the platform at height using a joystick. The steering cylinder sits on the steer axle (typically the non-drive axle), connected to the wheel spindles through tie rods. When the operator pushes the joystick left or right, the cylinder extends or retracts through its 125–150 mm stroke, turning the steer wheels.

Scissor lift steering differs from forklift steering in two important ways. First, the speeds are much lower — scissor lifts typically travel at 0.5–1.0 m/s versus 10–15 km/h for forklifts. Second, steering corrections happen while the operator is at height on the platform, so steering response must be smooth and predictable — no sudden wheel movements. The compact Φ40 mm bore at 20 MPa produces enough force to turn the steer wheels on hard indoor surfaces without the aggressive response that a larger cylinder would create.

The cylinder operates at 20 MPa — higher than the forklift steering cylinder (16 MPa) — because the scissor lift's smaller wheels and solid rubber tyres create more ground friction per unit of steering force. Browse the complete aerial work vehicle hydraulic cylinder range.

Scissor Lift Steering vs Forklift Steering

Both machines use hydraulic steering cylinders — but the operating requirements are fundamentally different:

Scissor Lift (EP-HCYY11112004)

Single-rod Φ40 mm, 20 MPa. Low travel speed (≤1 m/s). Operator steers from height via joystick. Smooth, predictable response critical — sudden movements risk destabilising the elevated platform. Solid rubber tyres create high ground friction.

Forklift (EP-HCYY11112002)

Double-rod Φ65–80 mm, 16 MPa. Higher travel speed (10–15 km/h). Operator steers from the cab at ground level. Fast, responsive steering needed for tight aisle manoeuvring. Pneumatic or cushion tyres with lower ground friction.

Key Advantages

  • Only 2.8 kg — the lightest hydraulic cylinder in the aerial work vehicle range. The compact size fits within the limited space of a scissor lift steer axle without adding significant weight to the machine's front end.
  • 20 MPa working / 30 MPa max — the 1.5× safety factor handles shock loads from kerb strikes and uneven floor surfaces. The higher pressure (vs forklift 16 MPa) compensates for the compact bore size and the solid rubber tyres' higher ground friction.
  • 400 mm installation distance — standardised pin-to-pin length across both stroke specifications (125 mm and 150 mm), simplifying steer axle design and replacement logistics.
  • Smooth joystick response — the small bore and moderate pressure produce progressive steering force — no sudden wheel snap. Critical for operator confidence when positioning the platform at height.
  • Hard-chrome rod — essential for scissor lifts that operate outdoors on construction sites, where dust, concrete powder, and rain challenge seal integrity. The Ra ≤0.2 µm finish protects the seals from abrasive contamination.

Frequently Asked Questions

What is the difference between the 125 mm and 150 mm stroke specifications?

The 150 mm stroke produces a larger wheel angle — resulting in a tighter turning radius for the scissor lift. The 125 mm stroke is used on models where the steer axle geometry limits the maximum wheel angle. Both share the same 400 mm installation distance and Φ40 bore.

Can the scissor lift be steered while the platform is raised?

Most self-propelled scissor lifts allow driving and steering at reduced speed when the platform is partially elevated (below a manufacturer-specified height limit). Above that limit, drive and steer functions are locked out for stability. The steering cylinder operates identically at any platform height — the lockout is in the control system, not the cylinder.

Why is the working pressure higher than a forklift steering cylinder?

Two reasons: first, the Φ40 mm bore is smaller than a forklift's Φ65–80 mm steering bore, so higher pressure is needed to produce adequate force. Second, scissor lifts use solid rubber tyres (non-marking, for indoor use) which create more ground friction than pneumatic forklift tyres.

How many steering cylinders does a scissor lift use?

One. A single cylinder connects the two steer wheels through tie rods. When the cylinder extends, both wheels turn together. The compact design keeps the steer axle assembly simple and lightweight.

What are common signs the steering cylinder needs replacement?

Sluggish steering response, steering drift (the machine pulls to one side), visible oil leakage at the rod seal or port connections, and excessive free play (dead zone) at the joystick centre position. Any of these symptoms warrant immediate inspection — steering integrity is critical for safe machine operation.

Can I order the steering cylinder together with the lifting cylinder?

Yes — the EP-HCYY11112004 steering cylinder and the EP-HCYY11112003 lifting cylinder can be ordered as a coordinated pair for scissor lift rebuilds. Browse the aerial work vehicle hydraulic cylinder range.

What Our Customers Say

★★★★★May 2026

"Replaced steering cylinders on 10 scissor lifts in our rental fleet. At 2.8 kg each, swapping them takes 30 minutes per machine. The 400 mm installation distance matched perfectly on all 10 units — no surprises."

B. Murphy — Rental Technician, Ireland

★★★★★Jan 2026

"Our scissor lifts operate on dusty construction sites. The previous aftermarket steering cylinders leaked within 4 months. Korea Ever-Power units have been running 11 months with zero leaks — the rod chrome quality makes the difference."

L. Dubois — Maintenance Manager, France

★★★★☆Sep 2025

"Good quality, competitive price — approximately 40% below OEM. We ordered both the 125 mm and 150 mm stroke versions for different scissor lift models. The joystick response is smooth and progressive."

M. Hansen — Service Engineer, Norway

★★★★★Jun 2025

"We ordered steering + lifting cylinders together for a 15-unit scissor lift fleet overhaul. Korea Ever-Power shipped both types in one delivery — consistent quality, consistent dimensions. All passed our incoming inspection."

J. Martínez — Fleet Director, Spain

★★★★★Feb 2025

"The 30 MPa burst rating gives us confidence on rough outdoor terrain. Our scissor lifts regularly drive over cable runs, expansion joints, and uneven concrete — the steering cylinder handles the shock loads without issue."

A. Korhonen — Site Manager, Finland
