NOTE:
46AJ & 51AJ Standard Configuration = 4WD + Oscillating Axle + 315/55 D20 Foam Tires
63AJ Standard Configuration = 4WD + Oscillating Axle + 355/55 D625 Foam Tires
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 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.

WARNING
Intermixing tires of different types or using tires of types other than those originally supplied with
this equipment can adversely affect stability. Therefore, replace tires only with the exact Skyjack-
approved type. Failure to operate with matched approved tires in good condition may result in
death or serious injury.
