Mobile elevating work platforms, or MEWPs, come in a variety of sizes and options. Choosing the right one for your jobsite isn’t as easy as knowing what height you need to lift to. You also need to consider how your MEWP is powered. A unit’s emissions, noise levels and engine type also need to be factored in the choice when selecting whether you need a manually propelled versus a self-propelled MEWP.
Manually Propelled MEWPs
Manually propelled MEWPs must be physically pushed or pulled to relocate. These products are elevated by electric power and often known as an aerial work platform (AWP, an aluminium lift, a manlift, a personnel lift or a push-around.
Applications best suited are work at height tasks in a single location. Manually propelled products tend to be both economical and easy to transport. For example, the ability to stow one of these units in a truck-bed could also save on delivery charges from the rental store or add flexibility for equipment owners with multiple facilities.
Manually propelled MEWPs offer a similar work height to many powered lifts, as well as comparably low floor load for sensitive surfaces such as gymnasiums, theaters and stages. They also offer similar degrees of compact maneuverability for congested jobsites, single or double door access and emission-free elevation.
Self-Propelled MEWPs
Self-propelled MEWPs are equipped with drive systems that allow the machine to be driven to the work area, such as a scissor lift. For larger applications, the ability to cover ground to quickly rotate between worksites makes self-propelled MEWPs a more productive solution. Especially where operators travel significant distances or make frequent trips. The gradeability (the ability to drive up slopes) and terrainability (the ability to travel over rough terrain) also help make self-propelled MEWPs high performers in construction projects.
Other needs requiring self-propelled MEWPs are the capacity and deck to carry multiple workers, their tools and materials to height. For example, scissor lifts offer up to 1,200- to 2,500-lb platform capacity with up to 21 ft of workspace.
