When the bottom of the tower adopts a reinforced design, the independent lifting height can reach 40 meters;
2. The lifting mechanism motor is a three speed motor with a coarse and short drum design, multi speed transmission, and simple operation and maintenance;
3. The symmetrical arrangement of the dual rotation mechanism ensures smoother rotation of the tower crane;
4. The lower chord of the crane arm is made of pointed square tube, which has a light weight.
The main limb of the standard section is made of large angle steel, which has high structural strength and good overall stability.
The lower chord of the crane arm is made of pointed square tube to increase the safety of the trolley.
The lifting mechanism adopts a four axis reducer, and the drum is of a thick and short type, which ensures smooth lifting and improves the service life of the steel wire rope.
The rotating mechanism adopts a symmetrically arranged dual planetary gear reducer, which rotates smoothly and has low impact.
The variable amplitude mechanism adopts a planetary gear reducer set inside the drum, with a compact structure and easy installation.
