1. The crane arm, balance arm, and transition joint are all connected by four point pin shafts, with high rotational stiffness;
2. The bottom of the tower adopts a reinforced joint design, with a large independent lifting height;
3. Adopting large-diameter external tooth meshing rotary bearings for more stable rotation;
4. Multiple arm length combinations to meet different user needs.
The standard section is a piece assembly structure, which is convenient for container transportation, and the inclined ladder makes it more convenient and safe to go up and down the tower crane.
When the tower crane is lifted, a working platform for operating the imported trolley is designed to increase safety.
Multiple combinations of boom lengths to meet the different needs of users.
The lifting mechanism adopts frequency conversion speed regulation closed-loop control, with smooth starting and braking, and no dragging phenomenon during heavy load lifting and lowering.
The large-diameter slewing bearing and two sets of symmetrical slewing mechanisms adopt external tooth meshing, torque motors, variable frequency speed regulation, and the tower crane rotates smoothly.
