Wood’s Powr-Grip MRTA611LDC2 - Manual (Page 5)

Rev 0.0/4-14 3 MRTA6-DC2: #35072
SPECIFICATIONS
Description: Designed for use with a crane or other hoisting equipment, MRTA6-DC2 lifters employ vacuum
to hold a load for lifting, and they provide manual 360° rotation and mechanically assisted,
manual 90° tilt movements for load manipulation.

Operating
Temperatures:
32° to 104° F [0° to 40° C]
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)

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.
1
Optionally available with alternative rubber compounds for special applications (see REPLACEMENTS PARTS LIST).
2
Standard with replaceable, closed-cell foam rings for rough or textured surfaces (see REPLACEMENTS PARTS LIST).

The illustrations under ASSEMBLY: T O C HANGE THE P AD F RAME C ONFIGURATION shows the Pad Spread and Maximum Load Capacity
for many of the possible MRTA611LDC pad frame configurations.

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 ACUUM P AD M AINTENANCE : 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.
