Pad-to-Load Friction Coefficient
The friction coefficient represents the lifter's ability to resist load slippage. The Maximum
Load Capacity assumes a friction coefficient of 1, based on testing of clean, new, standard
rubber vacuum pads on clean, dry, regular glass.
If the lifter is used under other conditions, a
qualified person
must first determine the effective lifting capacity.
1
Long-term exposure to heat, chemicals or UV light can reduce the friction coefficient of vacuum
pads. Replace pads and sealing rings or replaceable inserts every 2 years or more often when
necessary.
Pad Inspection
1A
Inspect each
vacuum pad
(fig. 1A)
according to
the
and
correct the
following faults
before using the
lifter (see “REPLACEMENT PARTS”, when applicable):
• Contaminates on the face (item 1 in fig. 1A) or sealing edges (item 2 in fig. 1A).
• Filter screen (item 3 in fig. 1A) missing from face.
•
Replace any sealing ring or pad insert that has damaged sealing
edges (see “T
