LCP – Locally Concentrated Pressure – is a measure of how hard the MEWP tire tread presses on the area
in direct contact with the floor. The floor covering (tile, carpet, etc.) must be able to withstand more than the
indicated values above.
â–ª
OFL – Overall Floor Load – is a measure of the average load the MEWP imparts on the whole surface
projected directly underneath it. The structure of the operating surface (beams, etc.) must be able to
withstand more than the indicated values above.
â–ª
The welder option will add approximately 158.8 kg (350 lb) to total MEWP weight and 79.4 kg (175 lb) to
the max. wheel load.
NOTE:
The LCP or OFL that an individual surface can withstand varies from structure to structure and is generally
determined by the engineer or architect for that particular structure.
