Design, Calculations, Safety Requirements and Test Methods for Mobile Elevating Work Platforms (MEWPs)
|Publication Date:||10 December 2018|
This American National Standard specifies safety requirements and preventive measures, and the means for their verification, for certain types and sizes of mobile elevating work platforms (MEWPs) Intended to position personnel, along with their necessary tools and materials, at work locations. It contains the structural design calculations and stability criteria, construction, safety examinations and tests that shall be applied before a MEWP is first put into service.
This Standard is intended to serve as a guide for manufacturers, remanufacturers, engineers and designers of MEWPs to achieve the following objectives:
a) prevention of accidents and personal injuries;
b) establishment of criteria for design, manufacture, remanufacture, rebuild/recondition,
c) establishment and understanding by manufacturers, remanufacturers, engineers, and designers of their responsibilities.
This American National Standard is not applicable to:
a) permanently installed personnel-lifting appliances serving defined levels;
b) fire-fighting and fire rescue appliances;
c) unguided work cages suspended from lifting appliances;
d) elevating operator position on rail-dependent storage and retrieval equipment;
e) tail lifts;
f) mast-climbing work platforms (see ANSI/SAIA A92.9);
g) fairground equipment;
h) lifting tables with a lifting height of less than 2 m (6.56 ft.);
i) builder's hoists for persons and materials;
j) aircraft ground-support equipment (see ANSI/SAIA A92.7);
k) digger derricks;
l) industrial trucks with elevating operator positions;
m) insulated aerial devices for use in live work on electrical installations; and
n) vehicle-mounted elevating and rotating aerial devices (see ANSI/SAIA A92.2).
