Pioneer Hydraulic Cylinder Part Numbers

- HR4719 — 16" rack gear / rack-pivot hydraulic cylinder
- HR4752 — 36" Strong Arm / arm-extension hydraulic cylinder
Pioneer Strong Arm Hydraulic Cylinders
Pioneer Strong Arm tarp systems use different hydraulic cylinders for specific system functions. HR4752 is used as an arm-extension cylinder on RP4500SAR and RP4500SARG systems, while HR4719 is used for the rack or pivot mechanism.
Because the cylinders perform different functions, stroke length alone should not be used to determine interchangeability.
Pioneer Gantry Hydraulic Cylinder
HR4520 is a 36" stroke gantry cylinder used in Pioneer Strong Arm Rack N Pinion tarp-system applications. Confirm the existing cylinder part number and tarp-system model before selecting a replacement.
How to Identify the Correct Pioneer Cylinder
Start with the Pioneer part number from the existing cylinder or tarp-system parts information. Then compare the stroke, closed length, mounting configuration, pin dimensions and hydraulic connections.
