Clamping Wire Rope To ensure complete safety, it is imperative that wire ropes are clamped correctly. The diagrams below are a guide only. Please refer to the relevant Australian Standards AS 2076 for further information.
Correct Spooling of Steel Wire Rope on Drum It is imperative to correctly spool wire rope onto a drum. Improper spooling induces torque within the rope, which in turn reduces the life of the rope.
However, provision must also be made for the safety coefficient and the design of the cable. All subsequent spooling should also take place with the line under tension.
tension to avoid any slack on inner layers that can be crushed or nicked against the groove walls by outer layers. In general, the tighter the line, the better the spooling, but the rope should be tensioned with at least 2% of the breaking load or 10% of the working load.
The Right Way
In any multi-layer spooling application it is important that when the rope is first installed on the drum, it is done so under

Lubricating Steel Wire Ropes All steel wire ropes supplied by Robertsons are lubricated at the time of manufacture, however, periodic lubrication with good quality acid free and moisture free lubricant during use is required to ensure best performance. The following are accepted ways to lubricate wire ropes during use.
Steel Wire Rope Cutting Procedure Hand cutters for cutting ropes up to 8mm in diameter are sufficient. Mechanical or hydraulic cutters will be required for wire ropes with larger diameters.
disturbance. Annealed wire must always be used for non-galvanised rope. For galvanised rope use soft, zinc coated wire.
Careless cutting can result in the balance of tension in the rope being destroyed. In every case, each side of the cut must be correctly seized to prevent strand

C: Both ends of the seizing wire are then pulled tight and twisted together for a length of one rope diameter. The twisted connection is then hammered into a strand valley.
B: The rope is tightly wrapped for a distance of approximately three rope diameters.
A: The rope and this wire end are now wrapped, moving away from the location of the intended cut.
D: After preparing the other side of the cut accordingly, the rope can now be cut.
