NOTE:
61/66T: Foam tires option will add approximately 1364 lb. (616 kg) to total aerial platform weight and 340 lb. (154 kg) to max. wheel load. OUP
will increase by 5% and LCP will increase by approx. 18%.
CE & AS Standard Configuration (61/66T)= 4WD + Oscillating Axle + 15" x 19.5" (38.1 cm x 49.5 cm) Foam Tires

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.
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.
OUP
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.
Total Aerial Platform Weight = Weight + platform capacity

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 original
Skyjack-approved type. Failure to operate with matched approved tires in good condition may
result in death or serious injury.
