The XCMG crawler crane spare parts system is designed around the two essential functions of "lifting operation + crawler travel." It covers all major systems including structure, transmission, hydraulics, electrical, and travel. Based on their functional roles, these parts can be divided into five main categories, each engineered specifically for the heavy-duty nature of crawler crane operations.

These parts form the "core skeleton" of crawler cranes that bear heavy loads, directly influencing lifting safety and operational stability.

XCMG's boom sections use Q690 high-strength alloy steel with full welding and shot-blasting for rust removal. The bending strength exceeds ordinary steel by 40%. The box-section design with reinforced ribs efficiently distributes lifting loads. Luffing cylinders feature double-acting design with honed inner walls and imported seals, controlling internal leakage to less than 0.3 mL/min.

Main hooks are forged from one-piece 42CrMo steel with medium-frequency quenching (HRC50-55 hardness) and can withstand three times the rated load without deformation. Pulleys are made of high-strength cast iron with chrome-plated grooves (friction coefficient as low as 0.15).

Modular design allows flexible combinations based on operational needs. Brackets feature thickened steel plates with locating pins for secure installation.

This system enables movement across various terrains, with parts designed for challenging conditions.

Standard shoes use high-manganese steel, while reinforced versions add wear-resistant alloy strips for 60% improved durability. Track links made of 20MnCr5 alloy steel feature precise manufacturing with pin-sleeve clearance controlled within 0.1mm.

Axial piston motors deliver 15% higher torque than industry standards. Planetary gear reducers achieve over 96% efficiency with wet brakes preventing slope slippage.

These components offer excellent sealing and stability, with radial runout controlled to less than 0.05mm.

The hydraulic system provides power for all crane movements through these key components:

Pumps offer over 95% volumetric efficiency at 35MPa pressure. Swing motors provide smooth rotation with high starting torque.

These components minimize leakage risks and ensure operational safety in extreme conditions (-40°C to 120°C).

Specialized fluids maintain viscosity under extreme conditions while filters protect precision components from contamination.

This system manages intelligent control and safety protection with high-stability components.

These components coordinate multiple crane movements with built-in safety features.

These systems monitor critical parameters and prevent dangerous operations.

These components ensure reliable electrical connections in harsh environments.

Although relatively inexpensive, these parts require regular replacement to maintain efficiency.

Ropes offer 30% higher breaking strength with protective coating. Brake shoes last over 8,000 cycles.

These components ensure effective sealing and lubrication under extreme conditions.

These parts enhance mobility and protect components from vibrations.
