Lifting machine crawler mobile cranes 50 ton for sale
crawler mobile cranes 50 ton machine has a wide range of application, including transportation infrastructure construction, city building construction, large load lifting and transfer, energy equipment installation and others.
1. Assembly/disassembly and transport economy
* Basic machine is an integrated transport design, without disassembling track frame and boom base, greatly save transport costs and improve the assembly/disassembly efficiency.
* Unique A-frame gantry self-erection technology, no need of cylinder can achieve self- erection, to realize crane quick assembly.
* Single counterweight weighing no more than 4t, small auxiliary lifting equipment can achieve complete counterweight assembly.
2. Opimized hydraulic system design
* Integrated design to reduce failure points, while reserve open space for assembly/ disassembly and maintenance.
* Use of highly integrated main valve, with the functions of multi-complex operation, control of combined flow, high/low speed selection, to ensure operation efficiency.
* Optional unique independent bypass filtration in the industry, strong magnetic adsorption device, strengthened hydraulic system filtration, and anti-emulsifying ability.
3. Main/ auxiliary hook one-key-switch-over function
One-key-switch is used to easily achieve main/auxiliary hook switch-over, for wider range of applications.
