The greatest risk to a stand-up forklift operator is being involved in a collision with immobile objects such as racking components. This even exceeds the risk of overturning.
Standup forklift underride can occur when a horizontal rack beam can penetrate the operator compartment. If there are no pallets or stock on the floor, and no bumpers at the height of the overhead guard, the forklift is free to keep backing up, crushing the operator between the rack beam and the front of the compartment.
The Backbone® for Reach Trucks, addresses the hazard of standup forklift under-ride. This occurs when a rack cross beam intrudes into the operator cabin, crushing the operator between the cross beam and the front of the cabin and/or the boom. This causes catastrophic, life-altering injuries and death. Under-ride occurs because the backs of most reach truck cabins are open, with no physical barrier between the operator and horizontal cross beams. The Backbone® is an easily installed ANSI compliant safety bar that acts as a bumper, providing that missing physical barrier.
