Pad-to-Load Friction Coefficient
The Maximum Load Capacity is based on a friction coefficient of 1, as determined by
testing of clean, new, standard rubber vacuum pads on clean, dry, regular glass.
If the
lifter is used under any other conditions, a qualified person must first determine the
effective lifting capacity.
2
Long-term exposure to heat, chemicals or UV light can reduce the friction coefficient of
vacuum pads. Replace pads every 2 years or more often, when necessary.
Pad Inspection
1A
Inspect the 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.
• Nicks, cuts, deformation or abrasions in
sealing edges.
Replace any pad that has
damaged sealing edges.
• Wear, stiffness or glaze.
1..... Not applicable to Flat Lifters.
2..... A “qualified person” has successfully demonstrated the ability to solve problems relating to the subject matter and work, either by possessing a
recognized degree in an applicable field or a certificate of professional standing, or by possessing extensive knowledge, training and experience.
