XCMG’s truck-mounted crane spare parts system covers the entire lifecycle of the equipment and can be divided into four core categories based on function and application scenario. Each type of spare part performs a specific function during equipment operation, jointly ensuring operational efficiency and safety.

1. Key Structural Parts

These spare parts directly impact the crane’s load-bearing capacity and structural stability, and are the “backbone” of the equipment’s safe operation. They primarily include:

Boom-related spare parts: such as pentagonal/hexagonal boom sections, telescopic boom sliders, boom pins, etc. XCMG’s genuine boom spare parts are made of high-strength alloy steel, precision forged, and heat-treated. Their bending strength is over 30% higher than that of standard spare parts, effectively preventing boom deformation and jamming. They are compatible with the boom structure designs of all XCMG crane models.

Slewing mechanism spare parts: including slewing bearings, slewing reducers, and slewing motors. The original slewing bearing features a double-row roller design with excellent sealing performance, enabling long-term operation in harsh conditions such as dust and moisture. When used with a special grease, it can reduce wear by over 70%.

Frame and chassis spare parts: such as frame crossmembers, outrigger cylinders, and outrigger pads. XCMG offers lightweight and heavy-duty chassis spare parts for different operating scenarios. The lightweight parts reduce overall fuel consumption, while the heavy-duty parts utilize thicker steel plates to meet the load-bearing requirements of lifting large equipment.

2. Hydraulic System Spare Parts

The hydraulic system is the “power center” of XCMG’s truck-mounted cranes. The precision and sealing performance of the related spare parts directly determine the smoothness and responsiveness of the equipment’s movements. Core spare parts include:

Hydraulic pump and motor spare parts: such as the main pump, slewing motor, and luffing cylinder. XCMG’s original hydraulic pumps utilize German Bosch Rexroth technology, with internal leakage controlled to below 0.5 mL/min, 50% lower than the industry average. This ensures stable power output during lifting operations and prevents “lift-off” situations.

Hydraulic valve and piping spare parts include multi-way valves, balancing valves, high-pressure oil pipes, and seals. The original high-pressure oil pipes utilize a four-layer steel wire wound structure with a pressure rating of up to 40 MPa, suitable for extreme temperatures ranging from -40°C to 120°C. The seals are made of fluororubber, offering excellent oil resistance and a service life over three times longer than ordinary rubber seals.

Hydraulic oil and filter spare parts: XCMG’s specialized hydraulic oil features demulsification, anti-foaming, and anti-wear properties, forming a stable oil film during equipment operation. Combined with high-precision hydraulic oil filters (with a filtration accuracy of up to 5 μm), they effectively filter impurities, prevent hydraulic system blockage, and reduce the risk of pump and valve wear.

3. Electrical System Spare Parts

The electrical system is the “nerve center” of equipment operation and safety control. The stability of its spare parts directly impacts the equipment’s control accuracy and safety protection functions. These spare parts primarily include:

Control unit spare parts: such as PLC controllers, operating handles, and display screens. XCMG’s original controllers utilize industrial-grade chips with a response speed as fast as 0.1 seconds, accurately identifying operational commands. Combined with a touchscreen display, they provide real-time display of parameters such as equipment load, oil temperature, and operating time, allowing operators to easily monitor equipment status.

Sensor and switch spare parts: These include torque limiter sensors, angle sensors, and emergency stop switches. The torque limiter sensor boasts an accuracy of ±1% and monitors the load and working range in real time. When the load approaches the rated load, it automatically issues an alarm and shuts down the machine, preventing overload accidents. The emergency stop switch features a waterproof and dustproof design with a trigger response time of less than 0.5 seconds, ensuring rapid shutdown in emergencies.

Lighting and wiring harness spare parts: such as work lights, wiring harness connectors, and fuses. The factory-manufactured work lights utilize LED light sources with a brightness of 2000 lumens and an illumination range of over 50 meters, meeting the needs of nighttime operations. The wiring harness connector features gold-plated contacts, which provide low contact resistance and effectively prevent electrical failures caused by poor contact.

4. Spare Parts

Although these spare parts are relatively inexpensive, they require frequent replacement, directly impacting equipment efficiency. These primarily include:

Wire Rope and Hook Spare Parts: XCMG’s original wire rope is made of zinc-plated alloy, containing 19 steel wires per strand. Its breaking strength is 25% higher than that of ordinary wire rope, and it is coated with a special anti-rust oil to effectively resist corrosion during outdoor operations. The hook is a one-piece forged steel structure with a hardened hook mouth, ensuring it can still meet safe load requirements even with 3mm of wear.

Brake Pads and Tire Spare Parts: Specific to crane braking needs, our original brake pads utilize semi-metallic friction material, maintaining a stable friction coefficient between 0.4 and 0.5, with a service life of over 5,000 braking cycles. Matching tires are available in both off-road and on-road configurations, depending on the chassis model. Off-road tires feature a tread depth of up to 15mm, suitable for complex road surfaces like construction sites, while on-road tires emphasize low rolling resistance, reducing fuel consumption during long-distance transport.

Grease and Seal Spare Parts: XCMG’s specialized greases are available in high-temperature (suitable for temperatures above 120°C) and low-temperature (suitable for temperatures below -30°C) to meet the needs of various operating conditions. Seals, including O-rings and oil seals, meet the sealing needs of various parts of the equipment, preventing oil leakage and impurities from entering.
