One of the key conditions for MEWP stability is the ability of the ground or structure to safely support the weight of the MEWP at its point of contact with the ground in all configurations. Failure to consider the load-bearing capacity of the ground could potentially cause the MEWP to go out of level, become unstable, and overturn. 

Modern MEWPs are lighter and more efficient compared to older equipment, for example an 80-foot mobile boom might have weighed 20 tons, 20 years ago, fast forward to today’s technology and we see 80-foot booms weighing just over half that weight. MEWPs may be lighter, and are fitted with more technical safety control systems, but that does not mean they will not overturn if they are used incorrectly or set up on ground or floors that are incapable of safely supporting them.

This document is intended to:
• Highlight the relevant hazards and associated risks for those who plan MEWP operations on various types of ground and suspended floors
• Identify measures that can be implemented to eliminate or reduce the risk of an incident or injury before, and while operating a MEWP
