L68B1 Mast Section How to balance the tower crane in installation and work?
Tower crane balance problem, how to achieve balance in the installation and work of tower crane? Although counterweight can solve some problems, when the boom is rising, the boom that has been adjusted to balance will not be balanced?

When the object rises, the line of action of gravity does not move, so the arm of force is constant.
First of all, when the tower crane is installed, the boom will rise 7 degrees. When the tip force reaches the bearing range, the angle between the big arm and the tower body is only 90 degrees, so the tower crane is not flat, and then the triangle between the tower cap and the balance arm and the lifting point of the big arm is qualitative. Therefore, the lifting can be relatively stable!

Secondly, the tower crane is fixed and attached, so the tower body is particularly stable and firm. Under static state, the tower crane is unbalanced and biased, which is also what the tower crane can bear. The faster the lifted object rotates forward under operation state, which means that the tower crane is nearly balanced. The connection between the balance arm and the big arm is movable, and it can self tilt up and sink, and the balance is realized automatically after the pulling of the auxiliary arm 。 If you have a chance to experience it, you will understand.
