The crane mainly consists of booms, hoisting mechanisms, luffing cylinders, slewing gears, outrigger cylinders, fuel injectors, hydraulic systems, safety devices, hook assemblies, and beams, columns, and other structural components. Among them, the telescopic mechanism (the extension and retraction of the boom, the horizontal and vertical telescoping of the front and rear legs), the hoisting mechanism (construction of a hoist motor, a reduction gear box, a reel, etc., and the lifting and lowering operation of a heavy object), and the amplitude changing mechanism (It is driven by one or two front double-acting cylinders) and a slewing mechanism (a reduction gear box and a hydraulic motor that completes a 360° full swing motion) are the core of the whole vehicle's lifting function.
The hydraulic system plays a vital role in the operation of all institutions. The key components of the hydraulic system include the main hydraulic pump, main control valve, outrigger operated valve, main and auxiliary winches, and rotary speed reducer. The main hydraulic pump consists of Driven by the chassis engine, the main control valve controls the slewing, telescopic, luffing and hoisting operations, respectively, and the outrigger operating valve controls the outriggers simultaneously or individually through the single or both side levers of the chassis.
