The PTO hydraulic pump is the core power component of a truck mounted crane’s hydraulic system. It is driven by the truck chassis engine through the power take-off unit, converting mechanical power into hydraulic power.
It supplies high-pressure hydraulic oil to control the outrigger extension and retraction for stable vehicle support. After the outriggers are set, the hydraulic power is switched to drive the crane boom’s luffing, telescoping and slewing movements. It cuts off power during traveling to avoid idle wear, ensuring safe and efficient lifting operations.
There is no fixed price for the undercarriage PTO pump of truck-mounted cranes. Its price varies greatly depending on model, adapted tonnage, original or aftermarket quality, purchase quantity and market conditions. The price on the page is for reference only and not a fixed quotation. Please inquire for the exact price according to your specific specifications.
