AEM has just released an updated version of its Truck-Mounted Forklift Safety Manual. The update includes more accurate information specific to different machine configurations; new guidance provided for traveling while unloaded; expanded instructions for operating on uneven terrain; expanded guidance for handling high loads, and a new section explaining load stability factors.
Here’s an excerpt from the section on load stability factors (page 34):
Before disengaging the forks from under the load, be aware of the following stability factors:
Factor 1: Loaded Boom
Use EXTREME CAUTION when working with a loaded boom or mast at its maximum extension or height. In this situation the forklift’s center of gravity is located at its most critical stability limits, so any adjustments made to the load can cause the machine to tip over. Always use the shortest boom length or mast extension possible. Use the forklift’s stabilizing outriggers, if equipped.
Factor 2: Releasing the Load
It may not seem obvious, but this action can be very dangerous! Use EXTREME CAUTION when releasing a load placed at a high elevation, especially if operating on an uphill grade. Removing the weight of the load immediately shifts the forklift’s center of gravity to the rear and increases the likelihood of tip-over. Lower the mast or boom and extend as soon as possible.
Factor 3: Traveling with Unloaded Boom
Traveling with an unloaded mast or boom that is elevated or retracted is DANGEROUS, as uneven terrain or soft ground can cause the machine to tip over. Extend the mast or boom (as specifi ed in the operator’s manual) and keep it as low as possible when traveling.
