Market context
CONAB’s July 2026 10th survey estimated 180.6 million tonnes of soybeans and 141.7 million tonnes of corn in the 2025/26 cycle. Those figures explain the commercial importance of harvest uptime, but they do not specify any cylinder.
Grain equipment sees dust, chaff, mud, wash water, fertilizer residues, vibration, road transport, and long idle periods. Specify the environment alongside pressure and dimensions.
Grain-tank lifting geometry
The grain-tank cover or extension can move through a changing lever arm. The worst force point may occur near the start of movement, when the cylinder line of action is least favourable. Obtain hinge locations, cylinder pin locations, centre of gravity, weight, friction, wind load if relevant, and the full motion envelope. Check both lifting and controlled lowering.
HCYY11112016 is explicitly labelled a grain tank lifting cylinder in the catalogue. Its model data can start a comparison, but the machine pin centres, ports, rod orientation, load-control circuit, and bracket widths must match the approved design.
Hydraulic and safety inputs
Record pump flow, measured working pressure, relief setting, valve type, hose size, cycle time, and whether the load can fall if a hose fails. The machine risk assessment may require a counterbalance valve, pilot check, mechanical lock, or transport restraint. The catalogue does not state an integrated valve.
Replacement inspection
Photograph the old cylinder extended and retracted, measure pin centres and pins, identify any bent rod or worn bushings, and inspect the machine brackets. A new cylinder installed into distorted mounts can fail quickly even when its pressure capacity is adequate.
