Wood’s Powr-Grip VLGG1011LAC - Manual (Page 15)

In Case of Power Failure
The lifter is equipped with a vacuum reserve tank, designed to maintain vacuum temporarily in
case of a 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.

WARNING: Load must be fully supported before releasing vacuum pads.
When the load is at rest and fully supported, push the vacuum release button on the movable
control pendant to force air into the vacuum pads, quickly breaking the vacuum seal. After the
pads have disengaged completely from the load, move the lifter away. Continue to hold the
release button until the pads are well away from the load; otherwise, the lifter would reattach
itself to the load.

CAUTION: Do not set the lifter against any surfaces which could soil or damage the
vacuum pads.
Parking feet are built into the bottom of the pad frame to support an unloaded lifter when not
suspended from a crane: Use the hoisting equipment to gently lower the lifter until the parking
feet support its entire weight. Make sure the lifter leans securely against an appropriate support;
then detach the hoisting equipment hook from the lift slings.
If the lifter is transported to another location, use the original shipping container and secure the
lifter so as to protect the vacuum pads and all other components from damage while in transit.
Storing the Lifter
Use the covers supplied to keep the vacuum pads clean.
!!-CE-!! In accordance with CE Standard EN 13155, the lifter is designed to rest on relatively
horizontal surfaces without tipping over. To store the lifter in this way, set the lifter with the
pads facing downward on a clean, smooth, flat surface. Since the lifter’s intended use does not
include tilting, be careful to protect the vacuum pads and support the lifter while tilting it to the
horizontal position.
