Wood’s Powr-Grip MTA6LP6FAIR - Manual (Page 3)

Rev 10.8/2-13 1 MTA4/6LP6FAIR: #35099
SPECIFICATIONS
Description: Designed for use with a crane or other hoisting equipment, MTA4/6LP6FAIR lifters
employ vacuum to hold a load for lifting, and they provide mechanically assisted,
manual 90° tilt movements for load manipulation.
Model Number: MTA4LP6FAIR (w/4 pads) MTA6LP6FAIR (w/6 pads)
Lifter Weight: 48 lbs [22 kg] 55 lbs [25 kg]
Max. Load Capacity: 200 lbs [90 kg] 300 lbs [135 kg]
(based on Per-Pad Load Capacity of 50 lbs [22.5 kg], rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces 1 )
Power Source: Compressed air, 80-150 psi [550-1035 kPa] line pressure, 2 SCFM [57
liters/minute] @ 80 psi [550 kPa]
Vacuum Pads: 6" [15 cm] nominal diameter, low profile (Model LP6F), standard rubber, spring-
mounted (¼" [7 mm] travel), with #60 filter screen
Pad Spread: Minimum Maximum (to outer edges)
Length: 13" [327 mm] 39" [991 mm]
Width: 9" [226 mm] 30" [760 mm]
Tilt Capability: Manual, 90°, with four-bar tilt linkage that minimizes operator effort and
automatically holds a correctly attached load in the upright or flat position
Vacuum Pump: Venturi type, 1 SCFM [28 liters/minute] nominal vacuum flow @ 80 psi [550 kPa]
Vacuum Reserve: Vacuum reserve system helps prevent immediate vacuum loss in case of power
failure.
Vacuum Gauge: Dial gauge indicates current vacuum level in positive inches of Hg and negative
kPa.
Options: Available with Model CM3PE2 - 2" [5 cm] Pad Spacers. This option enables the
lifter to handle loads with surface obstructions, such as windows with mullions.
See separate instructions about other options.
Operating Elevation: Maximum = 13,000 feet [3962 meters]
Operating Temperatures: 0° to 120° F [-18° to 49° 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; see MAINTENANCE and REPLACEMENT PARTS LIST for
more information. For the D ISPOSAL OF THE L IFTER after its service life, see
INTENDED USE.
ASME Standard BTH-1: Design Category "B", Service Class "0" (see www.powrgrip.com for more

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.
