Optimised design of transport and assembly / disassembly

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 5t. small auxillary lifting equipment can achieve complete counterweight assembly.

Optimised hydraulic system design

Integrated design to reduce failure points, while reserve open space for assembly / disassembly and maintenance. Use of highly integrated LUDV main valve, with the functions of multi-complex operation, control of combined flow, high/low speed selection to ensure operation effiency. Optional unique independent bypass filtration in the industry, strong magnetic adsorption device, strengthened hydraulic system filtration, and anti-emulsifying ability.

Universal and modular design

Common platform products with fixed jib, single top, both sided counterweight hook block, luffing mechanism, hydraulic pump and main valve block can achieve universal and interchangeable use. greatly reduce purchase, transport and maintenance costs.
Main / auxillary hook one-key-switch-over function (optional)
One-key-switch is used to easily achieve main/auxillary hook switch-over, for wider range of applications.

Hydraulic System

Hydraulic system adopts hydraulic proportional pilot control load sense LUDV system, to achieve load-independent flow distribution, with accurate velocity, sensitive operation, stable system and good fine movement. Special LUDV centralized main valve to realize combined operation, with compact structure and easy for maintenance.
Main winch and auxillary winch has double-pump combined flow function, to easily realize winch high/low speed control. Special slewing buffering circuit design, to realize stable slewing start and stop to meet the requirement of delicate lifting operation.

Crawler travel unit

Crawler travel unit is divided into left / right crawler, consisting track frame, crawler shoe, track roller, driver sprocket, guide roller, idle roller, travel device and tension device.
Track frame: Symmetrically arranged, one on each side, made of high-strength steel plate welded in box-type structure, insert type connection with car-body, drawer type clearance adjusting device to make sure there is not lateral “λ” type deformation and prevent collision between crawler shoes and lower roller.
Track Shoe: High strength wear resistant alloy steel casting, width 800mm, total 2×64=128 pieces.
Travel Gear: Constant close type planetary reduce, axial piston motor drive, strong travel power for movement such as straight travel, turn on site, one side turn, differential turn and travel with load with excellent agility and flexibility. Multiple-disc wet type constant close brake, spring brake, hydraulic loose brake guarantees excellent brake safety.
Gradability: 30%
