WPG MRPT1211LDC, Instructions Manual, Page: 5 / 38

Rev 2.0/4-18 3 MRPT1211LDC: #35064
SPECIFICATIONS
Model Number: MRPT1211LDC(O)
Description: Designed for use with a crane or other hoisting equipment, the MRPT1211LDC(O)
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: 12 volts DC, 32 amps
Battery Capacity: 35 amp-hours
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: MRPT1211LDC MRPT1211LDCO w/Telescoping Arms*
(to outer edges) 40" x 93" [1016 x 2362 mm] 40" x 120" [1016 mm x 3048 mm]
Lifter Weight: 1 488 lbs [222 kg] 545 lbs [248 kg]
Load Capacity: (rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces 2 )
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: 3 Powered, 90°; Speed = approx. 20 seconds; Duty = 58 tilts per hour
Vacuum Pumps: 2 diaphragm type, 1 SCFM [28 liters/minute] nominal airflow
or
1 diaphragm type, 3 SCFM [85 liters/minute] nominal airflow
Vacuum Reserve Tank: Vacuum reservoir helps prevent immediate vacuum loss in case of power failure and
extends battery life by reducing pump cycles required to maintain vacuum.
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" Hg [-54 kPa]).
Options: * Available with 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 optional features.
Operating Elevation: Maximum = 7000 ft [2133 m]
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
