As a global leader in construction machinery, XCMG strictly adheres to the same standards, processes, and quality control as the entire machine when producing crawler crane spare parts. Genuine spare parts offer three core advantages over third-party parts, ensuring the long-term and stable operation of your equipment.

1. Full-Process Quality Control, Ensuring Both Compatibility and Safety

XCMG crawler crane spare parts undergo 10 rigorous inspection steps from R&D to factory delivery to ensure quality compliance:

Raw Material Inspection: Raw materials such as steel, rubber, and electrical components undergo composition analysis and mechanical property testing (such as tensile strength and hardness) to ensure they meet design standards.

Processing Accuracy Inspection: Coordinate measuring machines, laser diameter gauges, and other equipment are used to inspect the dimensional accuracy of spare parts. For example, the diameter error of the boom pin is controlled within 0.01mm.

Welding Quality Inspection: Structural welds undergo X-ray or ultrasonic testing to ensure the absence of defects such as pores and cracks.

Hydraulic Performance Testing: Hydraulic pumps, valves, and other spare parts undergo a 12-hour continuous operation test at rated pressure to ensure leak-free operation and stable pressure.

Travel Performance Testing: Track assemblies undergo 1000 cycles on a test bench simulating muddy and rough terrain. Kilometer running tests ensure that the crawler tracks and drive wheels are free of abnormal wear.
Electrical performance testing: Electrical components undergo a 72-hour aging test in high and low temperature (-40°C to 85°C) and humid and hot (95% humidity) environments to ensure stable performance.
Safety performance testing: Safety components such as torque limiters and brakes undergo overload testing to ensure they effectively protect the equipment under extreme operating conditions.
Life testing: Consumable parts undergo accelerated life testing, such as wire ropes undergoing 100,000 bend tests, to ensure they meet service life standards.
Compatibility testing: Spare parts undergo installation testing with various XCMG crawler crane models to ensure 100% compatibility and no installation deviations.
Factory random inspection: Each batch of spare parts undergoes a random inspection of no less than 8% to ensure that defective products do not enter the market.

In addition, genuine spare parts are developed based on the overall design parameters of XCMG crawler cranes and fully match the equipment’s mechanical structure, hydraulic system, and electrical logic. For example, third-party spare parts for the slewing motor of a certain model of crawler crane may not fit properly due to dimensional discrepancies. However, genuine spare parts can be installed and used immediately, ensuring a 100% success rate and preventing equipment failures caused by improper fitting.

2. Synchronous Technology Upgrades to Meet Heavy-Duty Requirements

XCMG applies its core technologies for crawler crane development to spare part upgrades, ensuring that their performance is consistent with, or even surpasses, that of the new generation of equipment:

Structural Strengthening Technology: To meet the heavy-duty requirements of crawler cranes, laser cladding technology (which deposits a wear-resistant alloy layer on the surface of spare parts) is used on spare parts such as the boom and track shoes, improving wear resistance by over 50%. Topological optimization is employed in the counterweight bracket, reducing weight by 15% while increasing load capacity by 20%.

Hydraulic Energy Saving Technology: Load-Sensing Control technology is incorporated into hydraulic pumps and valves, automatically adjusting hydraulic oil flow based on the load. This reduces fuel consumption by over 20% compared to traditional components. A buffer device is incorporated into the hydraulic cylinder to reduce impact during boom raising and lowering, and outrigger extension and retraction, protecting the equipment structure.

Intelligent Monitoring Technology: Sensor modules are integrated into the new generation of spare parts. For example, a temperature sensor is installed in the crawler track to monitor the track’s operating temperature in real time. When the temperature exceeds 80°C, an alarm is generated through the controller to prevent excessive wear caused by poor lubrication. A differential pressure sensor is installed in the hydraulic filter element to automatically prompt a replacement notification when the filter element becomes clogged, ensuring a clean hydraulic system.

In addition, XCMG offers a “spare parts upgrade solution” for older crawler crane models. For example, early models of crawler cranes are equipped with intelligent torque limiter spare parts to enable them to have load monitoring and alarm functions; replacing new track plate spare parts improves the equipment’s passability on complex road surfaces, helping old equipment restore more than 80% of the performance of new machines and extend its service life.

3. Comprehensive Supply Chain and High Delivery Efficiency

XCMG has established 15 spare parts storage centers nationwide, covering core regions such as Northeast China, North China, East China, South China, Northwest China, and Southwest China. We stock over 6,000 types of crawler crane spare parts, enabling rapid response to customer needs:

Common spare parts such as wire ropes, seals, and filter elements are in ample inventory, enabling same-day ordering and next-day delivery. Same-day delivery is also available in select regions (such as Jiangsu, Shandong, and Guangdong).

Key spare parts such as boom sections, travel motors, and hydraulic pumps are delivered within 5-10 days through modular production and regional distribution.

Special spare parts such as customized counterweights and large slewing bearings are produced quickly by XCMG, with delivery times of no more than 20 days, significantly lower than the industry average of 30-45 days.
