Product Characteristics
● Strong lifting capacity
The main boom consists of 5 U-shaped boom sections which can extend to a maximum length of 42m, contributing to the crane’s superior comprehensive lifting capacity and securing Zoomlion’s leadership in the industry. The independently designed plate-type boom head and compact boom end realize optimal overlapping ratio as well as stronger lifting capacity of the main boom. The second generation of free boom telescoping technology, which is novel in the industry, increases stability during telescoping and brings the overall vehicle with higher anti-tipping capacity.
● High work efficiency
A hydraulic pilot control joystick is installed in the crane, which is capable of compounding movements of the main and auxiliary winches, the derricking mechanism, the slewing mechanism and the telescoping mechanism, therefore greatly increasing the crane’s lifting efficiency.
The crane is characterized in its convenient, flexible, stable and reliable operations which can be adjusted in a stepless way.
Single rope speed of the hoisting winch 1 and 2 can reach 135 m/min (at 4th layer on the drum).
● Stronger single wire rope pulling force
The main and auxiliary winches use a standard φ17 anti-twisting wire rope.
● Optimization of transportation, assembly and dismantling
Easy for transfer between working sites; the whole vehicle can be transported in one truck.
The crawler carriers can be extended and retracted, and the maximum transport width of the crane is 3 m.
