Roll daily maintenance to pay attention to what?
Q: roll daily maintenance to pay attention to what?
A: The important components of the reel as the rope hoist, by extrusion of the rope in the work process, bending and twisting of the pressure effect.
Station vast majority of accidents are usually caused by the roll, squeeze twist pull role. Therefore, in the course of routine maintenance, such as the discovery of Roll cracks should be immediately discarded, to eliminate security risks.
Secondly the roll the degree of wear of the rope grooves should not exceed 2 mm, and if it exceeds shall re-grooving, but the roll wall thickness not less than 80% of the original wall thickness, and roll up and down should not have cracks.
Deviation, wire rope on the drum when the angle between the wire and rope groove large wire it is easy to accelerated wear rope groove or even quit, causing severe wear of the wire rope in the roll daily checks and maintenance, such as found. Common reasons for hook pulley block is too small distance away from the reel, then do the appropriate adjustments. May also be due to the deflection of the hook pulley group reel safety position, and may also be caused due to the oblique hanging goods skew leaving rope quit.
Addition, replacement wire rope, wire rope wrapped around volume torsional stiffness (due the prehensile In wood roll on) do not relax, also make rope quit, even crossing a wire rope and pulley corrective together in order to prevent the accident, the rope suspension into a disk gradually release straightened, twisted Jin can completely disappeared.
