Learn How ANSI Safety Standards Are Changing Mobile Elevating Work Platforms (MEWPs)

Mobile elevating work platforms (MEWPs) lift workers, tools and supplies for the completion of many different types of overhead jobs. Formerly known as aerial work platforms, MEWPs are covered by new standards from the American National Standards Institute (ANSI) and the CSA Group. Before renting your next MEWP, you should be aware of some changes to the standards in these certain areas:

  • Familiarization. Through the new familiarization requirement, dealers and rental companies must offer familiarization and training to customers who request it.
  • Load sensing. With the new standards, MEWPs will be manufactured with load cells built into the platforms for monitoring weight. With your rented MEWP, it’s important to monitor the weight in the platform and disable functions if your load is above the load limit. If your machine is overloaded, take some weight out of the platform before continuing. Old machines are grandfathered in and do not need to be upgraded to meet the new requirements. Regardless of the machine you are using, it is important to not overload the platform.
  • Wind force requirements. Under new wind force requirements, certain new MEWPs are rated for outdoor use and may require reduced platform capacities and/or be equipped with heavier counterweights to meet standards. Newer MEWPs of the same model may weigh more than their predecessors. Ensure job-site surfaces and hauling equipment can handle the machine’s weight before using.
  • Tilt sensing requirements. This safety feature will automatically cut out lift and drive functions of the machine if the rated tilt angle is exceeded.
  • Entrance gates. Chain entrances are not acceptable on newly manufactured MEWPs, but are acceptable on older machines. When using a new MEWP, you may notice half-height, full-height or saloon-style gates to get onto the platform. This is to ensure safety when using the machine.
  • Tires. The option of air-filled tires will be limited as most newly manufactured rough terrain equipment will now be available with only solid body and/or foam-filled tires. Keep this in mind when planning for work that has soft ground or gravel.
  • Platform railings. Be aware of the raised railing height on select new models when renting your MEWP. The change was made for small indoor scissor lifts to fit through standard doorways. To maneuver through these doorways with the raised height, ask your rental store how to fold the railings before working on your next project.

Your local American Rental Association-affiliated rental store can help you understand these new standards through information and training and connect you with available rental products to meet your MEWP rental needs.

    The MEWPs are here to stay! There are plenty of high rise buildings coming up and the construction industry is in need to new innovations that will guarantee the safety of the workers. The article covers all the important aspects of MEWPs. Would love to know how the rental prices work out as opposed to buying MEWPs for large construction companies.
