Tower Crane Knowledge sharing：

How does the lifting arm and balancing arm of the tower hold the balance?
TBelow, how does the weight arm and balance arm of the tower crane balance? A brief introduction.
The tower crane balance arm is a structure formed by welding the I-shaped steel and angle steel groups. It is divided into two sections and is connected by an earplate pin shaft.

The tower crane balance arm is equipped with railings and passages, and the tail is equipped with a working platform. One end of the tower crane balance arm is connected to the rotating tower body with two special axles, and the other end is combined with a rigid pull rod connected to the tower cap. The tail is equipped with a balanced weight and lifting mechanism.

The lifting mechanism itself has an independent base, with four pins. The shaft is balanced on the tower crane balance arm. The weight of the balance varies with the length of the boom, with 13 tons for the 50-meter arm, 12 tons for the 44-meter arm and 11 tons for the 38-meter arm.

The balance arm of the tower crane is divided into two groups. The tower cap is connected with the cable ear plate of the tail of the balance arm of the tower crane by a special pin shaft, and the balance arm of the tower crane is hung to the horizontal position.
The tower lifting arm is a modular variable structure and is divided into nine sections. The upper and lower strings of the lifting arm are made of two corner steel welded square tubes.

The entire arm frame is a triangular section. The joints and knots are connected by a pin shaft. The disassembly is convenient. In order to improve the lifting performance and reduce the weight of the boom, The boom adopts a double suspension point variable section space truss structure. In the first section of the crane arm, a small car traction mechanism is placed, and a hanging basket is set up on the car to facilitate installation and maintenance.

The first section of the arm base is connected to the pin shaft used for the rotating tower body. In order to ensure the lifting arm level, there are two hanging points in the second and sixth sections, which are connected to the tower cap through these two points.
When assembling, the lifting arm must be assembled in strict accordance with the serial number on each arm, and no dislocation or random assembly is allowed. The maximum lifting arm is 50 meters.

According to the construction requirements, it can also be assembled into 44 meters long and 38 meters long. When the arm is 44 meters long, The position of the suspension point of the pull tower is unchanged; The position of the pull rod suspension point is also unchanged when the arm is 38 meters long.

The upper end of the two groups of lifting arms pull rods is connected to the tower cap ear plate through a special pin shaft, and the lower end is connected to the suspension hole of the upper string rod of the lifting arm by the special pin shaft, respectively, and the lifting arm suspension is taken as a horizontal form.
