ROUGH TERRAIN FORKLIFT TRUCK GENERAL SAFETY STANDARDS (cont.)
D.) SUSPENDED LOADS
A jib or truss boom should ONLY be used to lift and place loads when the machine is stationary and the frame
is level. Transporting suspended loads must ALWAYS be done slowly and cautiously, with the boom and load
as low as possible. Use taglines to restrict loads from swinging, to avoid overturn.
The handling of suspended loads by means of a truss boom or other similar device can introduce dynamic
forces affecting the stability of the machine that are not considered in the stability criteria of industry test
standards. Grades and sudden starts, stops and turns can cause the load to swing and create a hazard.
Guidelines for "Free Rigging / Suspended Loads"
1. DO NOT exceed the rated capacity of the telescopic handler as equipped for handling suspended
loads. The weight of the rigging must be included as part of the load.
2. During transport, DO NOT raise the load more than 12 inches (305 mm) above the ground, or raise
the boom more than 45 degrees.
3. Only lift the load vertically – NEVER drag it horizontally.
4. Use multiple pickup points on the load when possible. Use taglines to restrain the load from swinging
and rotating.
5. Start, travel, turn and stop SLOWLY to prevent the load from swinging. DO NOT exceed walking
speed.
6. Inspect rigging before use. Rigging must be in good condition and in the U.S. comply with OSHA
regulation §1910.184, "Slings," or §1926.251, "Rigging equipment for material handling."
7. Rigging equipment attached to the forks must be secured such that it cannot move either sideways or
fore and aft. The load center must not exceed 24 inches (610 mm).
8. DO NOT lift the load with anyone on the load, rigging or lift equipment, and NEVER lift the load over
personnel.
9. Beware of the wind, which can cause suspended loads to swing, even with taglines.
10. DO NOT attempt to use frame-leveling to compensate for load swing.
U.S. OSHA regulations effective November 8, 2010 (29 CFR Part 1926, Subpart CC - Cranes and Derricks in
Construction) include requirements for employers that use powered industrial trucks ("forklifts") configured
to hoist (by means of a winch or hook) and move suspended loads horizontally. In particular, this regulation
applies to any rough-terrain forklift (e.g., "telescopic handler") equipped with a jib or truss boom with a
hook (with or without a winch), or a hook assembly attached to the forks. [Note: This regulation is in
addition to the OSHA regulation that requires specific forklift operator training: §1910.178(l).]
When a forklift / telescopic handler is configured and used for hoisting, the employer must ensure that:
1. Forklift, lift equipment and rigging have been inspected (each shift, month and year) and are in
good, safe condition and properly installed.
2. An operator's manual and applicable load charts are on the forklift.
3. Work zone ground conditions can support the equipment and load. Any hazardous conditions in the
work area have been identified, and the operator notified.
4. Equipment is being used within its rated capacity and in accordance with the manufacturer's
instructions.
