The levelling castor set transforms mobile equipment and transport units into stable worktops with ease. The hydraulic pump of the levelling castor set is centrally attached to the application. A hydraulic hose is used to connect the four hydraulic cylinders to the pump. The levelling castors are lifted synchronously and silently using a hand crank. Uneven surfaces can be compensated for manually with the adjustable-height truck lock using a spanner. Each levelling castor system can lift a maximum of 750 kg. Two different sets are available in the standard range: Each set includes four levelling castors with a synthetic adapter plate and pre-assembled hydraulic hose, a hydraulic pump including a collapsible hand crank and an assembly set with an instruction manual. The hand crank can be removed from the HRLK-PATH 100KF-HYD-AK levelling castor set.
