ASSEMBLY
1) Open the shipping container and remove all materials for restraining or protecting the vacuum
lifter. Save the container for use whenever the lifter is transported.
2) Suspend the lifter from a crane as follows: Select hoisting equipment (crane and hoist, when
applicable) rated to carry the maximum load weight plus the lifter weight (see
SPECIFICATIONS: Load Capacity and Lifter Weight).
Note: Any application of the lifter must conform to all statutory or regulatory standards that
relate to the hoisting equipment when used in its geographical location (eg, relevant OSHA
standards in the USA).
WARNING: Hoisting equipment hook must be fitted with restraining latch to
prevent lift spool from slipping off under any circumstances.
Disengage the tilt latch (see OPERATION: T O T ILT THE L OAD ) and raise the lift bar to a vertical
orientation. Then attach the hoisting equipment hook to the lift spool.
Note: Some hoisting equipment hooks could interfere with an upright load that extends
beyond the lifter's pad frame. If the load would contact the hook during lifter operation, the
operator must prevent this by attaching a sling (or other rigging that does not interfere with
the load) between the hook and the lift spool.
WARNING: Any sling used must be rated to carry maximum load weight plus
lifter weight.
Use the hoisting equipment to raise the lifter out of the shipping container. Be careful to
avoid damaging any vacuum pads. Remove the pad covers and save them for use whenever
the lifter is stored.
3) Connect the power cable from the lifter to the power source as follows: Identify the label
indicating the voltage range (V) and frequency (Hz) required to power the lifter (located
where power cable connects to lifter). Wire the female connector provided to an appropriate
current-protected power source.
WARNING: Wiring must be done by qualified personnel, taking all appropriate
safety precautions.
Note: Be advised that brown-outs, overtaxed generators, extension cords, and other
conditions can reduce power input at the lifter. If the lifter does not receive adequate power
while lifting, this could result in an unexpected load release and a risk of injury to the
operator or others.
WARNING: Lifter that does not receive adequate power while lifting could
experience unexpected load release.
The power source must be equipped with a ground fault circuit interrupter, in order to reduce
the risk of electrical shocks.
WARNING: Power source must be equipped with ground fault circuit interrupter.
Make certain the power cable is routed so that it does not become tangled while operating
the lifter or hoisting equipment. Then push the power cable’s male connector into the female
connector and twist to secure them together. Now the lifter is operational.
4) Perform Operational and Load Tests for the lifter as directed in MAINTENANCE: T
