L I F T ONE LOAD AT A TIME. Do not lift two or more separately rigged
loads at one time, even if the loads are within the rated crane capacity.
USE ENOUGH PARTS OF LINE FOR HEAVY LIFTS AND CHECK ALL
LINES, SLINGS, AND CHAINS FOR CORRECT ATTACHMENT. To obtain
maximum lifting capacities the hook block must be set up with enough parts
of line. NO LESS THAN THREE. WRAPS of wire rope should remain on the
hoist drum. When slings, ties, hooks, etc., are used, make certain they are
correctly positioned and secured before raising or lowering the loads.
