The machine is a horizontal-jib, trolley-outrigger, top-rotatable hydraulic jib crane. The lifting capacity is 6 tons; the rated lifting torque at 50 meters is 470 kN.m, and the rated lifting torque at 44 meters is 500 kN.m.

(1) Performance parameters, working range of 50 meters, which has increased the working space of the tower crane.

（3） Work modes are diverse, with two types: fixed-base and wall-attachment, suitable for different construction objects. The fixed-base mode can reach a height of 30 meters, the wall-attachment mode can reach a height of 120 meters at a two-times rate and 60 meters at a four-times rate.

The lifting mechanism uses a three-speed motor and a single-speed reduction gearbox, enabling heavy-duty operation at low speed with a maximum speed of 68 meters per minute.

The rotating mechanism is equipped with a wire winding motor paired with a planetary gear reducer, a hydraulic coupling, and has high bearing capacity, smooth start-up, and a positioning function.

All safety devices are in place, ensuring a safe working environment.

(8) Easy to use and maintain.
