(Summary description)Different types of cranes usually use lifting torque as the main control. When the working range of the good price and quality QTZ250 (7030) tower crane increases or the heavy object exceeds the corresponding rated load, the overturning moment of the heavy object exceeds its stable moment, which may cause the tower crane to collapse.

The ratio of the height of the good price and quality QTZ250 (7030) tower crane to the size of the bottom support is large, the center of gravity of the tower body is high, the torque is large, the starting and braking are frequent, and the impact force is large. In order to increase the stability of the good price and quality QTZ250 (7030) tower crane, let's follow the editor of Huaxia Group to analyze the main reasons for the overturning of the tower crane:
1. Overload. Different types of cranes usually use lifting torque as the main control. When the working range of the good price and quality QTZ250 (7030) tower crane increases or the heavy object exceeds the corresponding rated load, the overturning moment of the heavy object exceeds its stable moment, which may cause the tower crane to collapse.
Second, inclined hanging. The overturning moment of the good price and quality QTZ250 (7030) tower crane will increase when the heavy object is slanted, and the horizontal component force and the vertical component force will be generated at the lifting point. An additional overturning moment occurs at the bottom support point of the tower crane, which reduces the stability factor and causes collapse.
3. The tower crane foundation of the good price and quality QTZ250 (7030) tower crane is uneven, the ground endurance is not enough, and the excessive verticality error will also cause the overturning moment of the tower crane to increase and reduce its stability. Therefore, we should carry out strict testing of the good price and quality QTZ250 (7030) tower crane from these key factors to prevent major equipment and personal safety accidents.
