ANSI Mobile Elevating Work Platforms

Formally known as aerial work platforms, they are now called mobile elevating work platforms under American National Standards Institute A92.20, which replaces A92.3, A92.5 and A92.6. The new ANSI A92 guidelines include design, safe-use and training standards. All North American manufacturers and operators need to understand and abide by the new safety features for compliance.

ANSI A92 MEWP changes

The new standards classify equipment into two different groups. Group A consists of MEWPs that move vertically but stay inside the tipping lines, and Group B includes all others, such as boom-type MEWPs where the platform extends past the machine’s chassis. In addition, the equipment is grouped into three types. Type 1 can only be driven in the stowed position, Type 2 can be driven elevated but is controlled from the chassis, and Type 3 can be driven elevated but is controlled from the work platform. The standards A92.20 (for design), A92.22 (for safe use) and A92.24 (for training) replaced standards A92.5 for boom-supported platforms and A92.6 for scissor-type platforms. Please familiarize yourself with the following key changes:

Load sensing

An active load-sensing device is required on all A92.20 MEWPs. Machines will actively monitor load and interrupt normal operations by sounding an alarm if overloaded. Users need to be sure no overloading occurs on machines built under A92.20.

Stability testing

Most rough terrain equipment is available only with solid tires or foam-filled tires based on the new stability testing guidelines. The A92.20 requires machines to be tested when air-filled tires are deflated.

Wind-force requirements

For outdoor use, machines may require increased machine weight for more stability and reduced platform capacities, particularly in scissor lifts and vertical masts.

Tilt-sensing requirements

Machines that could previously only operate on level surfaces can be used on slopes. These machines are required to have a tilt sensor alarm and cutout. If the incline surpasses the slope limit, the system will disable boom and drive functions.

Entrance gates

Flexible devices, such as chains, are not acceptable entrance gates. In addition, toe boards must be on all areas of the platform. Gates and toe boards replace chains on entrances for electric scissor lifts, vertical masts and boom lifts.

Platform railings

The railing height requirement has been raised for small indoor scissor lifts. To fit through standard doorways, taller, folding rails replace fixed, non-folding rails on select models.
