Product Description

Excellent chassis stability, low average fuel consumption, and high economy.
Extensive working scope of boom and fast lifting/lowering speed of hook.
Powerful loaded traveling, high lifting capacity, and high working efficiency.
The hook, boom, and counterweight can realize stepless speed control and combination motions.
Both hook and boom winches adopt three-stage planetary gears for speed reduction and torque enhancement, featuring high safety coefficient and high mechanical efficiency.
The machine is installed with moment limiter system to real-time monitor the operating status and guarantee the lifting safety.
