Controlling the Lifter and Load
When the vacuum gauge shows that the lifter is ready, use the hoisting equipment to raise the
lifter and load as needed to clear any obstacles in their path. A load in the flat position
automatically tilts toward the upright position when lifted, due to the lifter’s design (see T
O

to follow). Use the control handles to keep the lifter and load in the desired orientation
while they are suspended from the crane.
WARNING: Never allow any pad shutoff to be opened or closed while lifting.
Opening or closing a pad shutoff while the lifter is supporting a load could result in the release of
the load and possible injury to the operator or others. The operator must take all appropriate
measures to prevent any person or object from accidentally moving the lever of a pad shutoff
during the lift.
In Case of Power Failure
WARNING: Stay clear of any suspended load in the event of a power failure.
Although the lifter is designed to support the load for at least 5 minutes without power, this
depends on many factors, including the condition of the load and the lifter’s vacuum system (see

). If a power failure occurs, keep all personnel clear of the suspended load until it can safely
be placed on the ground or a stable support. Correct any deficiency before resuming normal
operation of the lifter.

The tilt feature allows the operator to lift a load in the upright position and land the load in the
flat position, or vice versa. Remember that the load requires more vertical space when tilting to
the upright position, as well as more horizontal space when tilting to the flat position. Make sure
there is sufficient clearance for the load to tilt without contacting the operator or any nearby
objects. Although tilting to the upright position is automatic, tilting to the flat position is normally
accomplished with the aid of the hoisting equipment during the landing.

AND THE

OAD
For a landing in the upright position, simply lower the load onto an appropriate support. For a
landing in the flat position, lower the lifter until the bottom edge of the load is supported; then
move the lifter forward, allowing the load to tilt while continuing to lower it.

WARNING: Load must be fully supported before releasing vacuum pads.
When the load is at rest and fully supported, place the slide on the pad frame control valve in the
“RELEASE” position.
