Attach the load to the load-block hook withslings or other approved devices.c. Make certain that the sling clears allobstacles.15.5.2.2 Moving the LoadaBefore moving the load, make certain that itis well secured <strong>and</strong> properly balanced in the slingor lifting device before lifting it more than a fewinches.b. Before starting to hoist, note the followingconditions:1. Multiple-part lines shall not be twistedaround each other.2. The hook shall be positioned over theload in such a manner as to prevent swingingwhen the load is lifted.3. Ifthere is a slack-rope condition,determine that the rope is properly seated on thedrum <strong>and</strong> is in the sheaves.c. Test stability before lifting heavy loads.Check outrigger footing. Lift load slightly offtheground <strong>and</strong> stop. Check the machine formovement <strong>and</strong> check to be sure the brakes areholding. Never use machine stability to determinecapacity. Ifthere are any indications oftipping,the machine is already overloaded for that workingradius.d. Do not use cranes for side pulls except whenspecifically authorized by a designated personwho has determined that the stability ofthe craneis not endangered <strong>and</strong> that the parts ofthe cranewill not be overstressed.e. Do not hoist, lower, or travel while anyone ison the load or hook, except as noted in Section15.5.2.6, "Lifting Personnel."f. Do not move loads above people.g. Test the brakes each time a load approachingthe rated capacity is h<strong>and</strong>led byraising the load afew inches <strong>and</strong> applying the brakes.h. Power down when lowering loads. Whenlowering heavy loads, keep the hoist brakes asreserve. Use a safety pawl on the boom-hoistdrum when not lowering.i. Do not lower the load below the point whereless than two full wraps ofrope remain on thehoist drum.j. Do not leave your position at the controlswhile the load is suspended unless required to do15-21Chapter 15Construction <strong>Hoisting</strong> <strong>and</strong> <strong>Rigging</strong>Equipment Requirements
