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.

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.
Total Aerial Platform Load
Wheel LCP OUP
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.
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.
