L46A1 Mast Section Problems to be paid attention to to to ensure the stability of Tower hoist

27-09-2019

The ratio of Tower height to bottom support size is relatively large, and the center of gravity of the tower body is high, the torque is large, the braking is frequent, and the impact is large. In order to increase its stability, the tower crane manufacturer should analyze and guarantee the stability of the tower crane. Pay attention to the following aspects:
Overloading

Different types of cranes usually use load torque as the main control. When the working range is increased or the weight exceeds the corresponding rated load, the overturning moment of the heavy object exceeds its stable moment, which may cause the tower to collapse.
II. Leaning
When hanging a heavy object, it will increase its tilting force moment. At the lifting point, horizontal and vertical force will be generated. At the bottom of the tower crane, an additional tilting force moment will be generated, thereby reducing the stability coefficient., causing the tower to collapse.

III. Foundation
The foundation of the tower crane is uneven, the ground endurance is not enough, and the vertical error is too large. It will also cause the overturning moment of the tower crane to increase, which will reduce the stability of the tower crane. Therefore, from these key factors, we must strictly check the inspection gates to prevent major equipment personal safety accidents.
