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) Connect the lifter to an appropriate compressed air supply (see SPECIFICATIONS: Power
Source), as follows:
Install the female quick connector (supplied) on the compressed air line. Connect the female
quick connector to the male quick connector leading directly to the air supply valve.
Adjust the air pressure regulator to supply an air pressure of 60 to 80 psi [415 to 550 kPa]:
Place the slide on the air supply valve in the “ON” position, to engage the compressed air
supply. Then pull up the adjustment collar on the top of the regulator, and turn the collar
clockwise to increase pressure or counter-clockwise to reduce pressure, as registered on the
pressure gauge. When the desired adjustment is obtained, push down the collar to lock it in
place.
Make certain the air line is routed so that it does not become tangled, kinked, pinched or cut
while operating the lifter or hoisting equipment (see step 5).
Note: Place the slide on the air supply valve in the “OFF” position when the lifter is not in
use; otherwise, the vacuum pump would continue to consume air, causing the air compressor
to cycle continually.
3) Select the location for the lift shackle: The lift shackle may be attached in any of 4 locations
on the lift bar, which are provided to optimize the hang angle of the lifter and load. Make
sure the lift shackle is secured by its restraining bolt.
4) 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).
If the lift bar of the lifter is resting in a horizontal orientation, raise it to a vertical orientation:
Engage the tilt actuator as though tilting a load to the flat position (see OPERATION: T
O
T
ILT
THE
L
OAD
); at the same time, manually lift on the lift bar to assist the actuator’s movement.
Then attach the hoisting equipment hook to the lift shackle.
WARNING: Hoisting equipment hook must be fitted with restraining latch to
prevent lift shackle from slipping off under any circumstances.
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 shackle.
WARNING: Any sling used must be rated to carry maximum load weight plus
lifter weight.
