Lower the block with the slings down to the load. Keep your eyes on the load and on the signalman. Remember, only one man should give signals except in an emergency. When the men have secured the slings to the load and are well out of the way, and the signalman has signaled to raise the load, engage the hoist and bring the load a few inches above the ground deck of the boat to be sure that the load is balanced.
Offshore: In rough seas you may not be able to do this, so greater care should be taken when hooking up the load. If the sling being attached to the load is attached with a basket hitch that is, wrapped around the load , be sure there are no sharp edges to cut the sling, and if there are, put a piece of wood between the sharp edge and the sling. When the load man or signalman signals to raise the load, engage the control lever slowly.
Hoist the load to where it will clear the handrail and other obstacles on the deck and slowly swing the load over the deck making sure that you do not swing over people and making sure no one is between the load and any obstructions. As the load is free swinging it could crush someone. On a production platform, if the load must be swung over a pressure vessel of any kind, the production equipment should be shut in and the pressure relieved.
Watching the load and the signalman, and using the power load lowering on your crane as well as the foot brake, smoothly lower the load to the ground deck.
Try not to stop the load on the way down, because even if you do it smoothly, the crane can be stressed at some point where it might break even with a slight shock. Opens in 14 hours and 6 minutes.

Composition Of Wire Ropes Installing Wire Rope Inspection Wire Ropes Defect Fibre Rope Fibre rope is a commonly used tool which has many applications in daily hoisting and rigging operations.
Readily available in a wide variety of synthetic and natural fibre materials, these ropes may be used as : a slings for hoisting materials b handlines for lifting light loads c taglines for helping to guide and control loads. Fibre Rope Synthetic Sling Synthetic fibre ropes have many advantages over natural fibre ropes including: a greater strength size for size b lighter weight size for size c greater elasticity or stretch d greater shock absorption because of greater elasticity Advantages Of Synthetic Sling Synthetic fibre ropes have many advantages over natural fibre ropes including: a greater strength size for size b lighter weight size for size c greater elasticity or stretch d greater shock absorption because of greater elasticity Send each sling for a proof load test at least every 12 months.
Look for: a any external wear such as abrasion or cuts and contusions. Thus, for rigging purposes the construction industry has used wire rope almost exclusively.
