MR1611LDC: #35050
SPECIFICATIONS
Model Number:
MR1611LDC
Description:
Designed for use with a crane or other hoisting equipment, the MR1611LDC lifter employs
vacuum to hold a load for lifting, and it provides manual 360° rotation movements for load
manipulation.
Power Source:
12 volts DC, 26 amps
Battery Capacity:
26 amp-hours
Vacuum Pads:
Sixteen 11" [28 cm] nominal diameter, lipped (Model G3370), standard rubber, spring-
mounted (¼" [7 mm] travel), with #60 filter screen
Pad Spread:
1
(to outer edges) Minimum
Maximum
Length:
40¾" [103 cm]
169" [430 cm]
Width:
12" [30 cm]
49" [125 cm]
Load Capacity:
(rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces

)
Per-Pad:
175 lbs [79.5 kg]
Maximum (w/4 pads):
700 lbs [320 kg]
Maximum (w/16 pads):
2,800 lbs [1,270 kg]
Lifter Weight:
685 lbs [311 kg]
Rotation Capability:
Manual, 360°, with automatic locking at each ¼ revolution (when desired)
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]).
Low Vacuum Warning Buzzer:
(if applicable)
Max Alarm Volume = 103 dBA at 2 ft [60 cm]. While the lifter is powered up, an audible alarm
warns the operator whenever vacuum is not sufficient for lifting the maximum load weight.
Options:
Available
with Remote Control System. The system uses a 310-320 MHz signal.
Available
with Short Lift Bar. This option is designed for applications involving minimal
clearance between the lifter and the hoisting equipment, such as installations under eaves or
similar low-clearance situations. Maximum Load Capacity = 1,800 lbs [815 kg].
See separate instructions about other options.
Operating Elevation:
Maximum = 6,000' [1,828 m]
Operating Temperatures:
32° to 104° F [0° to 40° C]
Service Life:
This lifter is designed to have a service life of 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
