ON TIRES
On tires operation, particularly pick and carry, must be
done in a slow, smooth manner over level terrain that
will support the crane, with the loads close to the
ground and the boom as low as possible to avoid the
load swinging unintentionally, causing injury or tip
over. Do not pick and carry with the jib since the load
is further extended from the machine and the jib can be
easily damaged.
The maximum boom length shown on the On Tire chart
is the maximum boom length that can be used at the
radius shown. This is done to limit the boom height
when working on tires. Do not exceed the maximum
boom length for the given radius.
.
“Stationary” means that the crane cannot be moved
when loaded to the levels shown in the on tire load
chart.
Ensure that the tires are inflated as shown in the rec-
ommended tire pressure chart. Refer to procedure for
tire inflation in Section 4, Page 4-12.
“Creep” means the crane can be moved at a max-
imum speed of one (1) MPH for a distance of 200 feet
and then a 30 minute waiting period is necessary to
cool the tires. Overheating will greatly reduce the life of
the tires.
Never move the crane carrying a load with the boom in
any position except straight over the front.
2.5 MPH means the crane can be driven at this speed,
or slower, with the tires at the proper inflation pressure
with the boom straight over the front.
