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. The dosage of the balance weight is in inverse proportion to the length of the balance arm, and the length of the balance arm is in proportion to the length of the crane boom. The balance weight is considerable, the light tower crane generally needs 3-4 t at least, and the heavy tower crane needs 30t nearly.
The tower crane is when increasing along with building site building, need carry out the rising of a lesson to the tower crane, then, the jacking crossbeam plays about the rising of key at the in-process of jacking, because the jacking head at jacking crossbeam both ends need the activity to be embedded into in the jacking mouth, then carry out the butt jacking downwards through the hydraulic stem, traditional all is that whether stable embedding jacking mouth is judged to the position of jacking mouth through the manual work in the range estimation, need exchange through the beeper when the discovery is unusual, not only information exchange speed is slow, still cause misoperation easily.
