Gross Aerial Platform Weight = Weight + platform capacity
▪
LCP – Locally Concentrated Pressure – is a measure of how hard the aerial platform 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.
OUP – Overall Uniform Pressure – is a measure of the average load the aerial platform 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.
The welder option will add approximately 350 lb (158.8 kg) to total aerial platform weight and 175 lb (79.4
▪
kg) to max. wheel load.
NOTE:
The LCP or OUP that an individual surface can withstand varies from structure to structure and is generally
determined by the engineer or architect for that particular structure.
