Rev 1.0/3-13 1 MR1611LDCO/DVS: #35048
SPECIFICATIONS
Model Number:
MR1611LDCO
Description:
Designed for use with a crane or other hoisting equipment, the MR1611LDCO 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
Minimum
Maximum (to outer edges)
Length:
40¾" [1035 mm]
169" [4296 mm]
Width:
12" [305 mm]
49" [1248 mm]
Load Capacity:
1
(rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces
2
)
Per-Pad:
175 lbs [79.5 kg]
Maximum (w/4 pads): 700 lbs [318 kg]
Maximum (w/16 pads): 2800 lbs [1270 kg]
Lifter Weight:
695 lbs [316 kg]
Rotation Capability:
Manual, 360°, with automatic locking at each ¼ revolution (when desired)
Vacuum Pump:
1 diaphragm type, 3 SCFM [85 liters/minute] nominal airflow
Vacuum Reserve Tanks:
3 vacuum reservoirs help prevent immediate vacuum loss in case of power failure and extend battery
life by reducing pump cycles required to maintain vacuum.
Vacuum Gauges:
3 dial gauges indicate 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: Audio buzzer is energized until vacuum level is sufficient to lift maximum load weight (higher
than 16" Hg [-54 kPa]). See appendix for warning buzzer instructions.
Options: Model EO10DVS - Dual Vacuum System. Two vacuum system circuits allow the lifter to maintain the vacuum level in
one circuit even if an unexpected vacuum loss occurs in the other one (eg, due to load breakage).
Available with Model EO8RC3 - Remote Control System. This option features a radio transmitter and
receiver that can activate apply and release functions at distances up to 250' [76 m]. The system
uses either a 310-320 or a 433-434 MHz signal, depending on requirements in your geographical
location.
Available with Model LB11SLB - 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 = 1800 lbs [815 kg].
See separate instructions about other options.
Operating Elevation:
Maximum = 6000 feet [1828 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 DISPOSAL OF THE LIFTER
after its service life, see INTENDED USE.
ASME Standard BTH-1:
Design Category "B", Service Class "0" (see www.powrgrip.com for more information)
Wiring Diagram: The following wiring diagrams are attached for reference in servicing the lifter or trouble-shooting a deficiency:
713-W01 [W04], 714-W01 [W01], 714A-W01 [A-W05], 714A-W02 [A-W02], 714A-W03 [A-W04]
!!-CE-!! Note: This symbol appears in the INSTRUCTIONS manual only when requirements of a CE Standard are 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.
