1. The lifting and slewing mechanisms are controlled by variable frequency speed control, ensuring smooth starts and stops.
2. The main structure of tower crane is made of low alloy steel material, which improves the low temperature use performance of tower crane.
3. The large diameter external tooth meshing rotary support is adopted, and the rotation is more stable;
4. Various arm length combinations to meet different user needs.
|
Standard section The standard section is an integral structure connected by pin shafts, with high machining accuracy, convenient for installation and use, and interchangeable with L46 standard sections, the standard section is equipped with a large platform oblique ladder, which is safe and convenient. |
 |
 |
Tower crane base The tower crane foundation is used with four support legs, which cooperate with the standard sections to ensure the foundation is level and vertical. |
|
The adoption of the standard section is introduced by the way of the introduction of the trolley, which improves the force condition of the slewing bearing and the slewing mechanism, and extends the service life. |
 |
 |
Rotating mechanism Two sets of rotary mechanism are symmetrically arranged, using frequency conversion motor, frequency converter speed regulation, reliable operation, and smooth start and stop. |
|
The electrical control cabinet and the resistance box are both made of stainless steel, which is corrosion-resistant; all electrical components are of well-known brands at home and abroad, ensuring reliable quality. |
