MTA4/6LP6FAC: #35097
SPECIFICATIONS
Description:
Designed for use with a crane or other hoisting equipment, MTA4LP6FAC and
MTA6LP6FAC lifters employ vacuum to hold a load for lifting, and they provide
mechanically assisted, manual 90° tilt movements for load manipulation.
Model Number:
MTA4LP6FAC (w/4 pads)
MTA6LP6FAC (w/6 pads)
Lifter Weight:
48 lbs [22 kg]
55 lbs [25 kg]
Maximum 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

)
Power Source:
See serial number plate for specific AC voltage, frequency and amperage.
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)
Nominal Length:
13" [330 mm]
39" [991 mm]
Nominal Width:
13" [330 mm]
30" [762 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:
Rotary vane type, 2.5 SCFM [71 liters/minute] nominal airflow
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 = 8000 feet [2438 meters]
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; see MAINTENANCE and REPLACEMENT PARTS LIST for more
information. For the D
