Parker Gear Pumps for Truck-Mounted Cranes

Parker gear pumps dedicated to truck-mounted cranes (also known as loader cranes) are core components of hydraulic systems, engineered to deliver reliable and efficient power transmission for crane lifting, luffing, and slewing operations. With decades of expertise in mobile hydraulics, Parker has optimized these gear pumps to meet the rigorous demands of construction, logistics, and heavy-duty transportation applications.

Key Features & Advantages

• High Pressure Resistance: Designed to operate stably at operating pressures up to 400 bar (5800 psi), ensuring sufficient power output for heavy-load lifting tasks .
• Robust Construction: Adopts high-strength aluminum alloy or cast iron housing, combined with floating side plate structure and roller bearing design, providing excellent load-bearing capacity and wear resistance .
• Efficient Performance: Optimized gear tooth profile and internal flow path minimize pressure loss and flow pulsation, achieving high volumetric efficiency and reduced energy consumption. The laminated piston ring design (for relevant series) further reduces leakage .
• Reliable Operation: Capable of tolerating low temperatures, high temperature shocks, and harsh working environments. Reduced noise levels and minimized leakage paths enhance operational stability and safety .
• Easy Installation & Maintenance: Compact envelope size enables simple and cost-effective installation, even in limited space on truck chassis. The straightforward structure facilitates quick maintenance and part replacement .
