Description
What Is the HCYY11112012 Aerial Work Vehicle Steering Cylinder
and What Does It Do?
The HCYY11112012 aerial work vehicle steering cylinder is a double-acting hydraulic cylinder that drives the steering axle of self-propelled elevated work platforms — articulating boom lifts, telescopic boom lifts, rough-terrain scissor lifts, and drive-capable vertical mast lifts. It receives hydraulic pressure from the machine’s steering control circuit and converts it to linear force at the steering knuckle, pivoting the drive wheel through its turning arc under the operator’s command.
The HCYY11112012 operates at a continuous working pressure of 21 MPa (210 bar) — the elevated pressure range that aerial platform steering circuits require because the machine’s raised centre of gravity creates significantly higher side-load on the steering axle than ground-level equipment faces. The withstand rating of 32 MPa provides a 1.52× safety factor above the working point, covering pressure spikes from sharp steering inputs and uneven terrain travel at height.
With a Φ63 mm bore, Φ35 mm chrome-plated rod, and a 320 mm stroke, the cylinder produces the steering force required for machines in the 6,000–14,000 kg operating weight range — covering the majority of self-propelled boom lifts used in construction, industrial maintenance, and civil infrastructure work across Canada and Australia. The 540 mm CTC pin distance and 13 kg weight enable direct fitment and one-person field installation during scheduled maintenance or unplanned replacement.

Why the HCYY11112012 Aerial Work Vehicle Steering Cylinder
Is the Correct Specification
Where the HCYY11112012 Is Specified
The aerial work vehicle steering cylinder is used wherever a self-propelled elevated platform requires active hydraulic steering — independent of platform height or load position.
Articulating Boom Lifts (6–18 m working height)
Steering load is highest at full boom extension over the machine’s side — a condition this cylinder is rated to handle at 21 MPa continuous. Used in construction, infrastructure maintenance, and industrial facility work.
Telescopic Boom Lifts (up to 30 m)
Fully-elevated travel on uneven ground demands consistent steering response. Binding or drift at 20+ metres is a tipping risk — the 32 MPa withstand rating covers pressure spikes from sharp steering inputs during elevated repositioning.
Rough-Terrain Scissor Lifts (4WD outdoor)
Construction site scissor lifts face higher shock loads from uneven ground than warehouse machines. The 32 MPa withstand rating provides the shock margin needed for rough terrain steering without overloading the barrel or end cap welds.

——Frequently Asked Questions
What Buyers Say——Aerial Work Vehicle Steering Cylinder
“Replaced four steering cylinders across our articulating boom fleet. All four matched 540 mm CTC exactly — no rework, no shimming. One technician completed each swap in under 90 minutes. CE certificates were accepted without issue at our CSA Z150 annual inspection.”

“Old cylinder had so much drift our operator said the boom lift was making its own route decisions. New HCYY11112012 — steers where you point it, every time. Operator stopped complaining. I stopped getting calls. Machine passed inspection. Life is measurably better.”
