L46A1 Mast Section The explanation of lifting part of Tower machine
The tower crane consists of three major mechanisms: lifting, turning, and amplitude. The three major mechanisms consist of lifting arms, tower bodies, turntables, supports, balance arms, bottom frames, and spires. There are also the same indispensable parts of the tower machine. It is a lifting part. Its tower machine accessories also have pulleys, rotary supports, hooks and brakes.
This article explains lifting parts:
First of all, in the parts of the tower machine, the largest number, the technical requirements are strict and the specifications are complicated steel rope. According to the functions of the steel wire rope used in the tower machine, there are: lifting steel wire rope, changing steel wire rope, arm frame pull rope, balance arm pull rope, car pull rope and so on. The characteristics of the wire rope are: the strength of the whole root is high, and the entire section is the same size, the strength is the same, the weight is light, the vibration load can be borne, the elasticity is large, the coil can be wound, the motion can be balanced at high speed, and there is no noise. After wear, the skin will produce many burrs, which are easy to find and easy to dispose of in time. The wire rope is usually made of a strand of fine steel wire with a diameter of 0.3 to 0.4 mm.
Secondly, it is the variable size car of the tower machine. It is a necessary part of a horizontal arm frame tower. The whole set of variable amplitude cars consists of frame structure, wire rope, pulley, wheel, guide wheel, wire rope support wheel, wire rope anti-roll, car traction rope tensioner and broken rope insurance. For the specialized horizontal arm frame(length is above 50M), a maintenance basket is hung on the side of the variable size car, and maintenance and maintenance can be carried out at each maintenance point. After the operation is over, the car returns to the root of the arm frame, decouples the hanging basket from the variable size car, and is fixed in a special branch of the arm frame structure.
