How to determine the location of the tower suspension? What should be paid attention to when lifting?
How to determine the location of the tower suspension? What should be paid attention to when lifting? When lifting a large part, the position of the hanging point must be reasonably determined.
If the application statement does not indicate the location of the hanging point, the hanging structure must indeed pay attention to two aspects:
1. Balance of suspended components. For long structural parts, such as lifting arms, balance arms, can be tested hanging in the ground mouth, determine a fair hanging point.

2. Structural strength at the suspension point and fixation of the suspension cable connection. If the strength of the hanging point is not enough, the structure will be destroyed, and the situation in the individual eyes will cause damage to all the structure parts. The sling cables shall not slip and fall off at the sling point. Individual Sling cables shall be connected to the nodes of the suspended structure and shall not be connected to the middle and abdominal rods of the main string. Padding blocks should be added between sling and object edges.
In addition, the issues to pay attention to when lifting the tower:
Tower hanging standard sections of different sections: Some tower hanging tower body standard section is divided into two or more specifications according to the strength of the bar parts, different specifications of the scale section shape is the same, only the main string wall thickness is different, in the appearance is not easy to distinguish.

After the height of the tower crane is determined, the device box must be added to the section as required by the use of the explanation book. The detailed model logo of the standard section on the tower must not be mixed.
Different arm length balance heavy block configuration: For tower cranes that can change arm length, the weight of the balance weight is changed with the length of the arm, and this should be noted when installing.

To be properly installed according to the number, specification and location of the balanced heavy blocks defined in the instruction manual. Unaccurate installation position of the balance weight block will cause the balance moment deviation between the lifting arm and the balancing arm to be too large, which will easily cause the tower crane to lose stability.
