The wire rope lubrication on the service life of the wire rope has a great influence, including phosphate coating wire rope, galvanized wire rope and light surface wire rope. The system lubrication of steel wire rope, can make the life of steel wire rope extend 2-3 times, so, to lubricate the steel wire rope on a regular basis, especially the elevator steel wire rope, maintenance work is more important, so that it is often in a good lubrication state.
The steel wire rope keeps passing through the pulley rope groove and reel, to check the steel wire rope on a regular basis. For does not twist the wire rope, because the structure is special, surround the entanglement must not destroy or interfere with the original rope stock between the fixed pitch, in order to prevent the rope core slippage or outer rope stock relaxation form birdcage shape. Wire rope is an important part of the lifting mechanism, to ensure the manufacturing quality of the conditions, the use of factors have a great impact on the service life of the wire rope. Otherwise, the wire rope in the winding process on the reel will disperse, thus reducing the service life of the wire rope.
Steel wire rope surround entanglement way directly affect the service life of steel wire rope or not more than 2 °, the use of maintenance has a great influence on the service life of steel wire rope. Choose the right type of wire rope and pulley material, by the professional staff on a regular basis to check, maintenance and use, structure to ensure that the central line of the wire rope and reel, pulley axis line in the midpoint of the declination angle α ≤ 1 ° 30′. It will extend the service life of the wire rope, reduce the construction interest, ensure the construction cycle, and progress the economic benefits. Wire rope lubrication before, should be the wire rope appearance on the accumulation of dirt and rust clean, grease heating to about 60 ° C, so that grease can fully penetrate to the interior of the wire rope.Prevent the wire rope many times reverse bending.
The steel wire rope keeps passing through the pulley rope groove and reel, talk about the maintenance and maintenance of the lifting crane wire rope on its life: lifting mechanism work. To be pulled, squeezed, friction, twisting and other load role, at the same time, following the wire rope through a series of pulleys, and from time to time by bending and squeezing the repeated action, will be flooded with fatigue broken wire phenomenon, coupled with wear and rust and other factors, intensify the development of wire rope broken wire, therefore, every week should be a wire rope appearance inspection, monthly should be a comprehensive in-depth detailed specific inspection, to a few broken wire to Properly dispose of good, to prevent the broken wire make other wire break; To individual section wire rope, to cut off in time, for example, not twist wire rope if fixed improperly, torque loss of balance, near the anchor end will occur birdcage phenomenon, if not cut off in time, will affect the life of the whole wire rope. If the hoisting mechanism uses the right rotation steel wire rope, when the direction of the reel rope groove from left to right, the rope must be wound out from the top of the reel, such as when the direction of the reel rope groove from right to left, the rope must be wound out from the bottom of the reel, if the hoisting mechanism uses the left rotation steel wire rope, when the direction of the reel rope groove from left to right, the rope must be wound out from the bottom of the reel, when the direction of the reel rope groove from right to left, the rope must be wound out from the top of the reel, therefore, the Steel wire rope winding must be carried out by professional staff to ensure that the wrap around tangle accurate, so as to ensure the service life of the wire rope.
