ASSEMBLY
1) Open the shipping container and remove all materials for restraining or protecting the vacuum
lifter during shipping. 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: Maximum 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.
If the lifter is equipped with the optional tilt lock, make sure it is either disengaged or locked
out (see OPERATION: T

: Using or Locking out the Optional Tilt Lock).
Then raise the lift bar to a vertical orientation and 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, being careful to
avoid damaging any vacuum pads. The control pendant for the hoisting equipment can be
attached to the lifter by inserting it into the hoist pendant basket provided. 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: Wire the female
connector provided to an appropriate current-protected power source (see serial number
plate for power requirements).
WARNING: Wiring must be done by qualified personnel, taking all appropriate
safety precautions.
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) Arrange the pad frame in the configuration that will provide optimal support of the load while
lifting (see T
