Hand-driven hydraulic pump for P&H R-125

The hand-driven hydraulic pump is an auxiliary component designed to provide hydraulic pressure for specific crane functions when the main engine is inactive. It enables the manual control of the boom, winch, and outrigger cylinders, allowing for adjustments or emergency operations when the primary hydraulic system is not powered. The unit utilizes a manually operated lever to drive a piston, which generates the necessary flow to actuate these critical machine systems.

This component is compatible with P&H R-125, R-200, and R-209 crane models. It features integrated check valves to ensure unidirectional fluid flow and is designed for installation within the machine hydraulic circuit to serve as a backup or secondary control method. By allowing operators to move or stabilize the crane components without the main engine running, this pump provides a manual override capability essential for specific maintenance tasks or emergency recovery procedures. It is engineered to maintain system pressure during manual operation, ensuring that the boom, winch, and outriggers remain responsive under non-standard operating conditions.
