Description
Designed for use with hoisting equipment, MRTA8-DC3 lifters support loads using vacuum and
manipulate loads using manual 360° rotation and mechanically assisted, manual 90° tilt motions.

Maximum Load
Capacity4
4...... The Maximum Load Capacity is rated at a vacuum of 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces with a friction coefficient of 1. Pad
compound, load rigidity, strength, surface conditions, overhang, angle, center of gravity and temperature can also affect the lifting capacity. A “qualified
person” should evaluate the effective lifting capacity for each use (see definition under “Rated Load Test”).

SAFETY
Wear personal protective
equipment that is appropriate for
the load material. Follow trade
association guidelines.
Do not remove or obscure safety
labels.
Do not make any modifications to
the lifter (see “LIMITED
WARRANTY”).
Use the lifter only in an approved
“OPERATING ENVIRONMENT”(see
“INTENDED USE”).
Do not use a lifter that is damaged,
malfunctioning, or missing parts.
Do not use a lifter if the sealing
edge of any vacuum pad is cut or
otherwise damaged.
Do not use a lifter to lift cracked or
broken glass.
Do not exceed the Maximum
Load Capacity or lift loads the
lifter is not designed for (see
“INTENDED USE”).
Do not use a lifter if the
Maximum Load Capacity or
any safety label appears to be
missing or obscured.
Make sure the contact surfaces of
the load and vacuum padsare clean
before attaching the lifter (see
“MAINTENANCE”).
Position the vacuum pads correctly
on the load before lifting (see
“OPERATION: Positioning the Lifter
on the Load”).
Do not lift a load if any vacuum
indicator shows inadequate
vacuum.
Keep unauthorized personnel away
from the lifter, to avoid injury in
case of an unintended load release.
Do not touch the vacuum release
controls during a lift.
Do not allow people to ride on the
lifter or the load.
Do not lift a load higher than
necessary or leave suspended loads
unattended.
Do not position a loaded or
unloaded lifter over people.
Before servicing a powered lifter,
place the power control in the
inactive position and, when
possible, disconnect the power source.

1)
2A 2B
Remove all shipping materials and save them with the shipping container for future use.
2) Suspend the lifter from appropriate hoisting equipment:
2.1)
Select a crane and/or hoist rated for the Maximum Load Capacity plus the
Lifter Weight.
Note: Any lifter use must comply with all statutory or regulatory standards for hoisting
equipment in your region.
2.2) Disengage any tilt locks or latches, and raise the lift bar (figs. 2A-C).
2.3) Attach the hoisting hook to the
lift point (figs. 2D-E).
2D 2E
Make sure
hook has
restraining latch
(circled).
2F
Only use rigging rated for Maximum Load
Capacity plus Lifter Weight.
Use
rigging (fig. 2F) as needed to
make sure the hook does not
interfere with the load.
