Material handling is dangerous. Improper use of this product might result in serious personal injuries.
Confirm that the load weighs less than the maximum rated load of your boom AND that your fork lift is rated to lift the
combined weight of the boom and the load.
Contact the manufacturer of your fork lift BEFORE using the boom. Request that the lift manufacturer provide:
1. Written approval to use the boom with your lift truck; AND
2. Markings (labels) for the lift truck that:
– Identify your LM-boom; AND
– Provide the approximate net weight of the forklift truck and boom at the maximum fork elevation with a
laterally-centered load. [29 CFR 1910.178(a)(5)].
DO NOT use the boom until the forklift manufacturer provides adjusted maximum rated load tags for your fork lift.
DO NOT attempt to lift loads weighing more than the rated load of either the boom or lift truck,
whichever is smaller
.
Maximum rated load information appears in the tables on pages 4, 6, 8, 10, 12, 14, 16, 18, 20, and 22.
Strictly adhere to all rules applied at your worksite regarding forklift operation, fork attachment usage, and load rigging.
ONLY use rigging having maximum load ratings that exceed the load weight.
DO NOT connect a load to only 1 hook, which will cause the load to rotate during lifting and transport operations. Loads
should connect to both hooks simultaneously.
