New ANSI & CSA Standard Changes affecting Scissor Lifts and Boom Lifts

In May 2017 the Canadian Standards Association (CSA) and December 2018 The American National Standards Institute (ANSI) published new standards that govern the design and use of aerial work platforms across North America. The last big change to these standards took place in 2006.

These standards set new guidelines for aerial work platform design, safe use and training. Drafted to be similar to international standards like AS/NZS, CE, GB and ISO, these changes better align North American manufacturers like JLG with the global market.

One of the biggest changes was the change from Aerial Work Platforms or AWPs to MEWPs (Mobile Elevating Work Platforms). With this there are now 2 groups, A & B. Group A are MEWPs with platforms that move vertically but stay inside the tipping lines (think scissor lift). Group B are all other MEWPS, typically boom-type, MEWPs where the platform extends past the machines chassis.

Other changes affect machine design:

  • Load Sensing - machines are required to actively monitor load and interrupt normal operations/sound an alarm if overloaded.
  • Wind Force Requirements - Machines to be rated for outdoor us may require reduced platform capacities and/or increased weight for more stability
  • Tires - Most rough terrain equipment will only be available with solid and/or foam-filled tires
  • Entrance Gates - Flexible devices like chains are no longer acceptable entrance gates and toe boards must be on all areas of the platform
