NAVIN ROPE MAINTAENANCE GUIDE

PACKING

Wire ropes are supplied in wooden reels or in bundles. The reels are covered with suitable hessian cloth and plastic to protect the rope from dust and other material damages during transit and storage. Ropes must be stored in reels, duly packed in dry condition free from possible by corrosive agent like moisture, dust or acidic fumes. If the ropes are to be stored under warm & humid conditions for long time, it is to be mounted on a horizontal shaft and turned over periodically. Reusable ropes must be stored in reels as new ropes and ropes should be re lubricated if it is stored for too long.

HANDLING Ropes require careful handling to ensure that the lay lengths are not disturbed. The following method should be used to unreel the rope from the bundle or the reel.

MEASUREMENT OF WIRE ROPE

To measure a wire rope we need to place the caliper along the opposite strands of the rope.

SEIZING & CUTTING OF WIRE ROPE

It is important to tightly seize the wire rope with the annealed wire to maintain the ends of the rope. If it is not done the wires and strands become slack with the consequent upsetting of uniformity of tensions in the rope. This results in the overloading of some strands, under loading of others, bird caging and breakage.

INSTALLATION & CARE OF WIRE ROPE

• Drum/ Sheave Diameter to rope diameter should be appropriate depending

upon the type of rope used. • The depth of groove should be selected so that the rope does not rub against

the flange of the sheave or each other while entering, running or leaving the groove.

• Angle of circular arc of the bottom of the groove should be at least 1200. • If the groove diameter is too small pinching of rope will take place and if it is

too large the rope will tend to flatten. • Rope, Sheaves, Drums and related attachments should be regularly inspected

for wear and damages. • Corrosion, wear & tear, fatigue and damages should call for immediate

attention of the responsible person in order to avoid accident. • Maintenance of wire ropes involved adequate lubrication. • It is better to lubricate lightly and frequently than heavily and rarely. • The periodicity of re-lubrication should depend upon prevailing conditions;

however, under normal conditions fortnightly schedule is recommended.
