Pay off

For wire rope with reel, place the reet on a stand which allows the reel rotate, control the rotation speed of the reel, pull of the wire rope slowly. For wire rope without reel, pull the wire rope in the direction reverse to the end of wire rope.

End treatment

Sizing: Iron wire is recommended to be used lo seize the wire rope, at the location whore the wire rope will be cut, put one end of the iron wire along the wire rope axis, and leave a length of 4 times diameter of wire rope; begin to wind the iron wire on the wire rope closely from the other side of iron wire at the cutting position, the winding length should be about 3 times of rope diameter, then strain the ends of the iron and screw it closely, the screw length should equals the diameter of the wire rope then the screwed section should be set between the groove of the strands. Rope clamp: Steel wire ropes are bended to a ring, fixed with wire, and then using double-saddle bolts clamping. Fuse end of wire rope: using special electric heating equipment of steel wire rope, under half melting state, through the chunk rotating wire rope and then the rope of all steel wire welding together forming conical end of wire rope.

Check pulley groove

Before install the now wire rope, check the pulley groove carefully, the groove must be smooth, the rope groove radius should be large than the wire rope radius by 7.5%. Use the special radius gauge to measure groove radius.

Check angle of fleet

Before install now wire rope, must check and measure the angle of fleet. Angle of fleet moans the included angle between the centerline of the горе and perpendicular line of pulley axes, which is measured when wind the rope till the edge of the drum. No matter it is groove drum or plain drum, the angle should not be more than 1o 30”.

Installation

When wind the rope on the drum in multi-layers, must coil the bottom wire rope closely under tension, otherwise the wire ropes in upper layer will wedge into the lower layer and cause damage by extrusion. After the wire rope is installed, it should be run for some lime under medium load with a low speed. After the wire rope adapt to the application conditions, then gradually increase the operation speed and increase the loading. Forbid to use the wire rope under heavy load in high speed as soon as it is installed.

Note: the new and unused wire rope is more likely to be extruded than the used wire rope.
