First of all, the tower crane installation, the arm will be up 7 degrees. The angle between the upper arm and the tower body is only 90 degrees when the weight of the tip reaches the bearing limit, so the tower crane is not flat, then the triangle is fixed between the tower cap and the balance arm, and the lifting point of the upper arm. So, in the lifting can be more stable! Secondly, the tower crane is fixed, is attached, so the tower is particularly stable. The balance of the tower crane is unbalanced in static state, and it is also the weight that the tower crane can bear. The objects that are hoisted in the working state will rotate faster and faster, which means the tower crane will be nearly balanced, the link between the balance arm and the upper arm is movable and can be tilted up and down by itself. The pull of the secondary arm automatically achieves the balance. You will understand if you have a chance to experience it yourself.
