MEWP Terminology and Classification

MEWP Types

• Type 1 MEWPs can only travel with the platform in a stowed position.
• Type 2 MEWPs can travel elevated and is controlled from the chassis.
• Type 3 MEWPs can travel elevated and is controlled from the platform.

MEWP Groups

• A Group – machine has a design that does not allow the main platform to extend beyond the tipping point. Example being a scissor lift.
• Group B – machine has a design that allows the platform to extend beyond the tipping line. Example being an articulating or telescopic boom.

ANSI MEWP Classification Examples

– Group A, Type 1MEWP: JLG 12 or 15 SP Push-Around Stock Picker
The aerial platform never extends beyond the chassis, and the machine may only be moved with the platform retracted.
– Group A, Type 3 MEWP: electric scissor lift or driveable stock picker
Both of these machines fit the description of Group A because the platform never extends beyond the equipment tipping line, and travel can be initiated from the platform. 
– Group B, Type 3 MEWP: Boom lifts 
The aerial platform extends beyond the wheels and the machine can be moved by the operator while on the elevated work platform.
