The balance weight is required for all upper slewing tower cranes. Its function is to support the balance weight, which is used to form the balance moment required in the design and opposite to the lifting torque direction. In addition to the counterweight, the lifting mechanism is often installed at its tail. The reason why the hoisting mechanism is placed at the end of the balance arm together with the balance weight can play a part of the counterweight role, and the distance between the rope drum and the tower tip guide wheel is increased, so as to facilitate the wire rope arrangement and avoid rope disorder. The amount of counterweight is inversely proportional to the length of the balance arm, and there is a certain proportion between the length of the balance arm and the length of the lifting arm. The balance weight is quite considerable. Generally, the light tower crane should be at least 3-4t, and the heavy tower crane should be nearly 30t.
