Data expansion:

Tower crane is the most commonly used lifting equipment on construction sites? Also known as "tower crane", it is used to hang steel bars, wooden beams, concrete, steel pipes and other building raw materials in the form of segmental extension (referred to as "standard section"). Tower crane is an indispensable equipment in construction site.

The function of tower crane tower tip is to bear the upper load from the jib rope and the balance jib rope, and transmit it directly to the tower structure through the rotating tower, turntable, bearing seat and other structural components. The top of jack-up tower has truncated cone column, forward or backward truncated cone column, herringbone frame and diagonal support frame. All top-swing tower cranes need to be equipped with balance weights, whose function is to support the balance weights, so as to form the balance torque required by the design in the opposite direction to the lifting torque. In addition to the counterweight, a lifting mechanism is often installed at its tail. The hoisting mechanism is placed at the end of the balance arm together with the counterweight, which can play the role of partial counterweight, increase the distance between the rope drum and the guide wheel of the tower tip, facilitate the winding of the wire rope and avoid rope disorder. The size of the counterweight is inversely proportional to the length of the balance arm, and the length of the balance arm is proportional to the length of the boom. The balance weight is quite large. Generally, light tower cranes should be at least 3 ~ 4t, and heavy tower cranes should be nearly 30t. Tower crane-Baidu encyclopedia
