L68A1 Mast Section Lifting parts of the tower crane
First of all, in the tower crane lifting parts, the largest number of technical requirements and specifications are complicated wire rope. Tower Crane with wire rope according to different functions: lifting wire rope, amplitude wire rope, boom pull rope, balance arm pull rope, trolley pull rope, etc. . The characteristics of the wire rope are: the strength of the whole rope is high, and the whole rope has the same section size, the strength is the same, the weight is light, it can bear the vibration load, the elasticity is big, it can be wound into a coil, it can balance the movement at high speed, and it has no noise After wear and tear, the skin will produce a lot of Burrs, easy to find and easy to dispose of. Steel wire ropes are usually made by twisting strands of fine steel wire 0.3-0.4 mm in diameter into strands, and then strands are twisted into rope. Second, is the Tower Crane amplitude car.
It is a necessary part of Horizontal Jib Tower Crane. The whole set of luffing trolley is composed of frame structure, steel wire rope, pulley, traveling wheel, guide wheel, steel wire rope supporting wheel, steel wire rope anti-off roll, trolley traction rope tensioner and rope-breaking safety device. For extra-long horizontal boom (over 50m in length) , a maintenance hanging basket is attached to the side of the luffing trolley. After the operation, the car drives back to the root of the arm frame, so that the hanging basket is decoupled from the luffing car and fixed on a special support on the arm frame structure.
