Product Introduction
The XCA450 is a 450-tonne class Generation G all-terrain crane, featuring a rated lifting capacity of 450 tonnes and a rated lifting moment of 13,500 kN·m. Its main boom comprises seven sections extending to 80 metres, with the main boom plus jib achieving a maximum lifting height of 130 metres, delivering performance approaching that of 500-tonne class cranes. Employing single-engine power technology, it delivers energy savings, reduced consumption, and lower maintenance costs. Featuring efficient self-assembly/disassembly, multi-mode steering, and intelligent travel control, it offers convenient relocation and excellent manoeuvrability. Electro-hydraulic proportional controls ensure precision operation, while comprehensive safety features and comfortable cab provide an optimal working environment. Widely applicable for heavy-duty aerial operations including wind turbine maintenance, shield machine installation, bridge erection, petrochemical equipment hoisting, and high-rise construction, it serves as a highly efficient and reliable lifting solution for major engineering projects.

Product Operate Guide
Prior to operation, conduct a comprehensive inspection of the entire machine structure, hydraulics, wire ropes, safety devices, and outrigger pads, ensuring the ground is firm and level.
Strictly select the corresponding lifting capacity chart according to working conditions. Overloading, diagonal pulling, and excessive rotation speed while lifting loads are strictly prohibited.
Outriggers must be fully extended and securely supported. Lifting operations may only commence once the specified pressure is achieved.
Operate with smooth, controlled movements. Maintain constant speed during lifting, luffing, and slewing; avoid abrupt stops, sharp turns, or sudden drops.
Constantly monitor safety system alerts such as the load moment limiter. Obey instructions from designated ground personnel. No personnel shall remain beneath the load or boom.
Upon completion, retract the boom and superlift device. Park in a secure area, disconnect power, perform cleaning, and complete inspection records.
FAQ
1. DIFFICULTY STARTING EQUIPMENT AFTER LONG-TERM STORAGE, EVEN WITH A CHARGED BATTERY?
The fuel system may have vapor lock due to diesel evaporation, or the injector needle valve assembly may be stuck from residual oil buildup.
2. GREASE FITTINGS CLOGGED WITH DIRT AND SAND, PREVENTING GREASE INJECTION?
First, thoroughly clean the exterior of the fitting. Then use a fine needle to clear the steel ball inside the fitting. Finally, attempt grease injection again.
3. DOES DRAINED OLD ENGINE OIL CONTAIN SHINY METALLIC FLAKES?
Severe warning! Abnormal internal engine wear exists. Immediate disassembly and repair required.
4. FINE STRESS CRACKS APPEAR NEAR STEEL STRUCTURE WELDS?
Caused by residual welding stresses or fatigue cracks from long-term alternating loads. Prompt welding repair and stress relief required.
5. IS THERE UNIFORM, SLIGHT WEAR WITH A SHINY SURFACE ON THE HYDRAULIC CYLINDER PISTON ROD?
Normal. These are normal friction marks from contact with the guide sleeve seal.
6. DOES THE HYDRAULIC SYSTEM PRODUCE SIGNIFICANTLY DIFFERENT NOISES WHEN COLD VERSUS HOT?
Normal. Cold oil has higher viscosity, increasing pump suction resistance and causing cavitation noise. After warming up, viscosity returns to normal, and noise primarily stems from mechanical friction and fluid flow.
