Mobile Machinery Hydraulic Cylinder

Agricultural Trailer Plate Lift Cylinder
EP-HCYY11112036 · Φ40mm · Stroke 200mm · 16 MPa · 4.5 kg · Compact

The compact lift cylinder for agricultural trailer ramps and tailgates. At only 4.5 kg and 371 mm installation distance, this cylinder raises and lowers the trailer's loading plate — allowing livestock, equipment, and bulk materials to be loaded and unloaded safely. The lightweight design adds minimal weight to the trailer while providing reliable hydraulic operation powered by the tractor's PTO-driven hydraulic system.

How the Trailer Plate Cylinder Operates

Agricultural machinery with hydraulic cylinder

Agricultural trailers — livestock trailers, equipment haulers, and flatbed trailers — use a hinged rear plate (ramp or tailgate) for loading and unloading. The plate lift cylinder raises this plate from its lowered (ramp) position to its closed (vertical/transport) position, and lowers it again for unloading.

The 200 mm stroke provides the angular range needed to swing the plate from horizontal (ramp down) to vertical (closed). At Φ40 bore and 16 MPa, the cylinder produces approximately 20 kN of lifting force — enough to raise a steel or aluminium trailer plate weighing 50–200 kg, including the weight of any ramp extensions or locking mechanisms.

The cylinder is powered by the tractor's hydraulic system through quick-connect couplings. When the tractor's PTO-driven pump provides pressure, the cylinder extends to raise the plate. Lowering is controlled by a metering valve for safe, controlled descent — preventing the plate from slamming down. Browse the full mobile machinery hydraulic cylinder range.

Why 4.5 kg Matters on an Agricultural Trailer

Towed Weight Limits

Agricultural trailers must comply with road weight limits when towed between fields. Every kilogram of hydraulic equipment reduces the payload capacity. At 4.5 kg, the plate lift cylinder adds negligible weight — less than a single bale of hay.

Field Environment Durability

The cylinder operates in mud, rain, livestock waste, and agricultural chemicals. The hard-chrome rod and sealed design resist this corrosive environment. The compact 371 mm installation distance keeps the cylinder tucked close to the trailer frame, protected from impacts during field operations.

Tractor Hydraulic Compatibility

The cylinder operates from the tractor's existing hydraulic supply (typically 16–20 MPa) through standard quick-connect couplings. No additional pump, reservoir, or power source is needed — the trailer's hydraulic functions are powered entirely by the tractor.

Frequently Asked Questions

What tractor hydraulic pressure is required?

The cylinder operates at 16 MPa working pressure — compatible with virtually all tractor hydraulic systems, which typically supply 16–21 MPa. Connect through standard quick-connect couplings to the tractor's rear hydraulic outlets.

Can this cylinder be used on livestock trailers?

Yes — the plate lift cylinder raises and lowers the rear ramp on livestock trailers, allowing animals to walk on and off. The controlled lowering speed (via metering valve) prevents the ramp from dropping suddenly, which could startle livestock.

How many plate lift cylinders does a trailer use?

Typically 1–2, depending on the plate width and weight. Wider trailers (over 2 metres) may use 2 cylinders — one on each side of the plate — for balanced lifting. Contact Korea Ever-Power with your trailer model for the correct configuration. Browse the mobile machinery hydraulic cylinder range.

What Our Customers Say

★★★★★Jun 2026

"Fitted the EP-HCYY11112036 on our livestock trailer ramp. At 4.5 kg it's barely noticeable on the trailer. The ramp lifts smoothly and lowers gently — no slamming. Our cattle load and unload calmly."

S. O'Connor — Livestock Farmer, Ireland
