Machine Design Standard

ANSI A92.20 & CSA B354.6

This standard focuses on the design, calculations, safety requirements and testing methods for mobile elevating work platforms (MEWPs). It serves as a guide for manufacturers and engineers so they can build compliant machines.

What’s changed?

Load Sensing:
Machines are required to actively monitor loads and interrupt normal operations if they become overloaded.

Wind Force Requirements:
To be rated for outdoor use, machines may require reduced platform capacities and/or increased weight for more stability. Machines must be clearly marked if they are rated for indoor use only.

Tires:
Most rough terrain equipment will only be available with solid and/or foam-filled tires based on new stability testing guidelines.

Tilt Sensing Requirements:
Machines are required to have a tilt sensor alarm and may have a mechanism that disables certain boom functions if the incline surpasses the slope limit.

Folding Rails:
The railing height requirement has been raised for small indoor scissor lifts. Taller folding rails will replace fixed, non-folding rails on select models so they can fit through standard doorways.

Machine Markings & Documentation:
Machines must be clearly marked with the date of the last annual inspection and should have an updated manual on board that includes all new definitions and required information.

Who does it impact?

Manufacturers are impacted the most by these machine design changes. They have until March 2020 to bring their machines into compliance with new work platform standards. Rental companies and dealers also need to be aware for training and servicing purposes.

For end users, changes like load sensing will require advanced planning because jobs that were previously done with overloaded machines will be impossible to complete with compliant equipment. They will need to carefully consider the application when choosing a MEWP for the job.
