● The control of the working device consists of luffing control, lifting control and counterweight control. The hydraulic reversing valve is controlled by a pressure-reducing pilot control valve, which is simple and labor-saving in control, with good fine-tuning performance, and is easy to install on the body.

● There is one joystick for the control of hook and boom, and another one for the counterweight control, which can be operated conveniently and quickly under various working conditions, and ensure the user’s precision requirements with high efficiency.

● The hydraulic motors of the hook and boom winches offer high volumetric efficiency, and the balancing valve eliminates secondary skidding of the winch and shaking of the empty hook. Moreover, the clutch in the hook winch enables free lowering of the hook.

● Chassis has a good stability, low fuel consumption and cost-saving.

● The working range of the boom is wide, and the lifting and lowering speed of the hook is fast.

● Large bearing capacity, heavy lifting capacity and high work efficiency.

● The hook, boom, and counterweight can choose speed freely and realize combine motions.

● Both the hook and the jib winch use three-stage planetary gears for deceleration and torque increase, with high safety factor and high mechanical efficiency.

● The Cummins engine adopts high-efficiency fuel injection pump, which has the characteristics of excellent performance, stable quality, strong component versatility, and low maintenance cost.
