Background

The tower crane is the most common hoisting equipment on the construction site, also called tower crane, and is used for hoisting construction raw materials such as reinforcing steel bars, wood ridges, concrete, steel pipes and the like for construction by the extension (height) of one section and one section (called standard section for short). The tower crane is an indispensable device on a construction site.

The tower crane (tower crane) tip has the function of bearing the upper load transmitted by the boom guy rope and the balance arm guy rope, and directly transmits the upper load to the tower body structure through the rotary tower, the rotary table, the bearing seat and other structural components. The self-elevating tower top is provided with a truncated cone column type, a forward-inclined or backward-inclined truncated cone column type, a herringbone frame type and an inclined support frame type. The upper slewing tower crane is required to be provided with a balance weight, and the function of the upper slewing tower crane is to support the balance weight so as to form a balance moment which is required by design and has the action direction opposite to the lifting moment direction. In addition to the counterweight, a hoisting mechanism is often provided at the tail. The hoisting mechanism and the balance weight are arranged at the tail end of the balance arm together, so that partial balance weight function can be achieved, and the distance between the rope reel and the tower tip guide wheel is increased, so that the steel wire rope can be conveniently wound and rope disorder is avoided.
