1. When the bottom of the tower is reinforced, the independent lifting height can reach 40 meters;
2. The lifting mechanism motor is a three-speed motor with a coarse short-type drum design, multi-speed transmission, and simple operation and maintenance;
3. The double-rotation mechanism is symmetrically arranged, and the tower crane is more stable;
4. The lower chord of the boom is made of pointed angle steel pipe, which is light in self-weight.
|
Standard section The standard section main limb is made of large angle steel, the structure is strong, and the whole machine is stable. |
 |
 |
Lifting arm The boom's lower chord is made of pointed-angle square tube to enhance the safety of the trolley. |
|
Lifting mechanism The lifting mechanism adopts a four-axis reducer, the drum is thick and short, the lifting is stable, and the service life of the steel wire rope is improved. |
 |
 |
Rotating mechanism The slewing mechanism adopts a symmetrical arrangement of double planetary gear reduction machine, which has stable slewing and small impact. |
