NOTE:

The

LCP

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.

min

- Total aerial platform weight with no options

max

- Aerial platform all options

LCP

Locally Concentrated Pressure

is a measure of how hard the aerial platform presses on the areas in direct

contact with the floor. The floor covering (tile, carpet, etc.) must be able to withstand more that the indicated values
above.

OUP

Overall Uniform Pressure

is a measure of the average load the aerial platform imparts on the whole surface

directly underneath it. The structure of the operating surface (beams, etc.) must be able to withstand more than the
indicated values above.
