how to determine the location of the tower crane? What problems should be paid attention to when hoisting? When the Tower Crane installs large components, the position of the lifting point must be determined reasonably. If the lifting point is not marked in the application specification, two aspects should be paid attention to: 1. Balance of the lifting construction. For long structural parts, such as crane arm and balance arm, the proper lifting point can be determined by ground test. 2. Structural strength at the lifting point and fixing of the sling connection. If the hanging point strength is not enough, will destroy the structural components, the individual eye, the situation will cause all structural components damage.
