The tower crane has a large working space, and is mainly used for the vertical and horizontal transportation of materials and the installation of building components in the construction of house buildings. Tower crane is composed of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower body, boom and base. The working mechanism has four parts: lifting, amplitude changing, turning and walking.
Now let ’s talk about how the tower crane is balanced? See the following points for details:
1) The balance can only be carried out after the slewing bearing feet are free from the tail plate of the tower body.
2) Push the joystick of the hydraulic pump station to the "upward lifting" direction and lift upward until the slewing bearing feet have just left the fish plate.
3) Check whether the tower crane is balanced, if necessary, tow the trolley for trimming.
4) The exact position of the traction trolley can be found by checking whether the slewing bearing feet and the fish plate are on a vertical line. It can also be verified by the minimum pressure required for jacking up as shown on the pressure gauge of the hydraulic pump station.
5) The balance position of the towing trolley of the boom can be attached to the diagonal web of the boom as a mark, but it should be noted that the distance of the mark depends on the length of the boom, so the length of the boom is different and the distance is marked. It should also be different.
