Custom Aerial Work Platform Hydraulic Cylinders

Custom Aerial Work Platform Hydraulic Cylinders

Aerial work platforms use hydraulic cylinders for functions such as boom elevation, platform leveling, steering or outrigger movement. Because these functions affect personnel safety, the cylinder must be reviewed as part of the complete machine and its control and holding circuits. Yongjian can work from the equipment manufacturer’s drawings and duty specification to develop a custom cylinder configuration for approval.

Map the full movement

Share the linkage model, platform and payload conditions, cylinder pin-center positions, required stroke and travel limits for every operating position. Identify normal and exceptional load cases, including the forces relevant to stowed, raised and transport positions. The machine designer should check stability, clearances, rod buckling and mounting loads throughout movement. A cylinder selected only by bore and stroke may miss the effect of changing linkage leverage.

Coordinate machine safety functions

Specify the hydraulic circuit, operating and peak pressure, flow, intended speed, holding and emergency-lowering requirements, and any interface to a load-holding valve or other safety component. The control and safety concept must be validated by the platform manufacturer against the applicable machine requirements. Mountings, pins and bearings need a clear responsibility split between the cylinder supplier and the equipment builder.

Adapt the cylinder to the environment

Describe outdoor exposure, temperature, water, dust, road transport and storage conditions. Confirm port orientation, hose clearance, rod protection, seals, wipers and corrosion treatment against the actual duty. For replacements, include the original drawing, machine serial range and any observed leakage, corrosion or wear so the new unit can be checked for compatibility.

RFQ and acceptance information

Send the function and linkage drawing, load cases, stroke and closed length, mounting geometry, pressure, fluid, cycle and environment, safety-circuit interfaces, quantity, inspection plan and required documents. Factory dimensional, pressure and leakage checks should be agreed before production; machine-level safety validation remains with the equipment manufacturer. Contact Yongjian with your drawings to discuss a custom solution.
