MRPT1211LACO: #35065
SPECIFICATIONS
Model Number:
MRPT1211LACO
Description:
Designed for use with a crane or other hoisting equipment, the MRPT1211LACO lifter
employs vacuum to hold a load for lifting, and it provides manual 360° rotation and
powered 90° tilt movements for load manipulation.
Power Source:
See serial number plate for specific AC voltage, frequency and amperage.
Vacuum Pads:
Twelve 11" [28 cm] nominal diameter, lipped (Model G3370), standard rubber, spring-
mounted (¼" [7 mm] travel), with #60 filter screen
Maximum Pad Spread:
MRPT1211LACO
MRPT1211LACO w/CF3TAO Option*
(to outer edges)
40" x 93" [1016 x 2362 mm]
40" x 120" [1016 x 3048 mm]
Lifter Weight:
667 lbs [303 kg]
730 lbs [332 kg]
Load Capacity:
(rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces
1
)
Per-Pad:
167 lbs [75.5 kg]
Maximum:
2000 lbs [905 kg]
Rotation Capability:
Manual, 360°, with automatic locking at each ¼ revolution (when desired)
Tilt Capability:
2
Powered, 90°, with adjustable electronic speed controller; Maximum speed = approx. 9
seconds per tilt travel in one direction; Maximum duty = approx. 360 tilts per hour
Vacuum Pump:
Diaphragm type, 3 SCFM [85 liters/minute] nominal airflow
or
Rotary vane type, 4 SCFM [113 liters/minute] nominal airflow
Vacuum Reserve Tank:
Vacuum reservoir 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.
Vacuum Lift Light:
Green light is energized whenever vacuum level is sufficient for lifting maximum load
weight (higher than 16" [-54 kPa]).
Options:
Model LB1ETO High-Duty Tilt with Speed Control. This option dramatically increases tilt
duty and gives the operator precise control over tilt speed, as well as reducing apply
and release times for the lifter.
*
Available
with Model CF3TAO Telescoping Pad Arms. This option enables a lifter to
handle loads with different dimensions from those of the standard pad frame. See
separate instructions about these and other options.
Operating Elevation:
Maximum = 10,000 feet [3048 meters]
Operating Temperatures: 32° to 100° F [0° to 38° 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.
