Problems solved by technology

This is unmatched by electric cranes
Electric rail tower cranes have high disassembly costs, poor mobility, and poor lifting capacity. It is imperative to replace them with full-hydraulic large crawler cranes.
[0003] The disadvantages of the crawler cranes in the prior art are: 1. The product itself is heavy, has no self-disassembly function, and is difficult to transport and install, which greatly prolongs the construction period; 2. There are few working methods and poor adaptability, which cannot meet different hoisting requirements. Requirements; 3. The hydraulic drive system is backward, with high failure rate and unstable performance, which cannot meet the needs of current engineering construction

Embodiment 1

[0014] Embodiment one: if figure 1 , figure 2 As shown, the fully hydraulic crawler crane includes an intermediate body 1, crawler belt assemblies 3 are installed on both sides of the intermediate body 1, a revolving body 2 is installed on the intermediate body, and a boom assembly, an operating room 22, and a boom assembly are installed on the revolving body 2. power and hydraulic system and counterweight 23, the vehicle body 1 is equipped with hydraulic support legs 14 that can support the crane off the ground, the crawler belt assembly 3 can slide along the mounting arm 11 of the intermediate body 1, and the A push-pull device 12 that can push and pull the crawler belt assembly 3 along the mounting arm 11 is provided between the intermediate body 1 and the crawler belt assembly 3 , and a locking device 13 is also provided between the crawler belt assembly 3 and the intermediate body 1 .

[0015] The hydraulic support leg 14 is hinged on the vehicle body 1 through a pin sh...

Embodiment 2

[0028] Embodiment two: if image 3 , Figure 4 , Figure 5 As shown, its structure is basically the same as that of Embodiment 1, and the difference lies in the structural form of the boom assembly, which is in the form of a tower lifting structure, including the main arm 24a, which is in a fixed state during work, The root of the main arm 24a is provided with a main arm anti-tilt device 24a1, an auxiliary arm 24b that is hinged with the main arm 24a and can realize amplitude change, a main support 24c, an auxiliary support 24d, an auxiliary Arm front cable 24e, secondary arm rear cable 24f, rear cable tensioning device 24g; main hook steel wire rope 24h for lifting and lowering heavy objects on the main hook by retracting and retracting; main luffing rope for realizing the amplitude of the auxiliary arm 24b by retracting and retracting .

[0029] The back cable tensioning device 24g includes a hydraulic cylinder 24g1 hinged to one of the main support 24c and the main arm 2...

Abstract

A fully-hydraulic caterpillar hoister is composed of a central body, hydraulic supporting legs for raising the hoister from ground, a caterpiller assemblage, a push-pull system for driving caterpillers, and locating-locking system. It features its self-detaching function.

Description

technical field [0001] The invention relates to a crane, in particular to a crawler crane. Background technique [0002] Fully hydraulic crawler cranes are the development trend of crawler cranes in the world at present. For decades, the development of crawler cranes in the world has changed from mechanical to mechanical-hydraulic and then to full hydraulic. It has been proved by practice that full hydraulic crawler cranes have stable operation, large lifting capacity and high lifting height. And it can realize the advantages of stepless speed change, inching position, easy operation, light weight, convenient transfer and disassembly. This is unmatched by electric cranes. Electric track tower cranes have high disassembly costs, poor mobility, and poor lifting capacity. It is imperative to replace them with fully hydraulic large crawler cranes. [0003] The disadvantages of the crawler cranes in the prior art are: 1. The product itself is heavy, has no self-disassembly fun...
