Service Life:

This lifter is designed to have a service life of at least 20,000 lifting cycles, when used and
maintained as intended (vacuum pads, filter elements and other wear-out items are excluded).

ASME Standard BTH-1:

Design Category "B", Service Class "0" (see www.powrgrip.com for more information)

!!–CE–!! Note: This symbol appears in the

INSTRUCTIONS manual only when requirements of a CE Standard are different from

requirements of other standards that also apply to this vacuum lifter. CE requirements are mandatory in geographical areas where CE
Standards apply, but may be optional in other locations.

Optionally available with alternative rubber compounds for special applications (see REPLACEMENT PARTS LIST).

The Maximum Load Capacity is rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces, with a friction coefficient

of 1 (see MAINTENANCE: V

: Pad to Load Friction Coefficient). A qualified person should evaluate the

effective lifting capacity for the actual application. In addition to the effect of friction between the vacuum pads and load, the
lifting capacity may be affected by the following load characteristics: rigidity, strength, surface conditions, overhang, angle, center
of gravity and temperature.
