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 MEWPelectric 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 MEWPBoom lifts 
The aerial platform extends beyond the wheels and the machine can be moved by the operator while on the elevated work platform.
