L68A1 Mast Section Introduction of Tower Sling Steel Rope
The characteristics of the steel rope of the tower crane 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 carried, the elasticity is large, the coil can be wound, and the motion can be balanced at high speed. 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.
The tower machine uses interactive twists and turns, which are not easy to loosen and twist. As far as the shape of the rope section is concerned, it is most appropriate to use a tower machine for high-rise building construction to use multiple non-torsional wire ropes. This kind of wire rope consists of two layers of rope strands. The two layers of rope strands are in the opposite direction, and the principle of balancing the rotation moment is used. Made of, The free end does not twist when it is forced.
The safety coefficient of Tower rope and variable steel wire rope is generally taken as 5 to 6, the safety factor of car traction rope and arm frame pull rope is 3, and the safety factor of elevator lift rope of Tower machine is not less than 10. The safety coefficient of wire rope is an indispensable safety reserve coefficient, and the maximum allowable safety load of wire rope must not be increased without authorization by this safety reserve surface.
Due to the importance of wire ropes, it is necessary to strengthen the regular and comprehensive inspection of wire ropes and store them in warehouses with closed dry surfaces, wooden floors or asphalt concrete floors, so as not to corrode, do not damage the surface during loading and unloading, and erect them when stacked. Systematic lubrication of wire ropes can improve service life.
