How is the wire rope of electric hoist fixed on the drum
Drum is the indispensable electric hoist and other small hoisting machinery accessories, one of the wire rope on the drum is also very important fixed, fixed method are many, the wire rope on the drum fixed several ways: Wire rope on the drum fixed method usually used clamp screw or wedge, using the principle of friction to the fixed rope tail, requirement of fixed method is reliable, and helpful for inspection and installation, in a fixed place for wire rope is not excessive bending, damage.
Wedge fixed method: this method is used in small diameter wire rope, which is not used for bolts, and is suitable for multi-layer winding drum. 2, the long plank is fixed: by the press of the screw, the length of the strip along the wire rope is fixed to the drum.
Clamp fixed method: using the pressure plate and screw wire rope, the method is simple, reliable work, convenient for observation and examination, is the most common form of fixed, the downside of this approach lies in the occupied space is larger, therefore, cannot be used for multi-layer winding. The number of platen is at least two for safety reasons. In order to ensure that wire rope fixed reliable, reducing platen or wedge force, under the fetch device to limit position, except the fixed coil of wire rope on the drum, should also keep security 1.5 3 circle.
