Wood’s Powr-Grip MR1611LDC - Manual (Page 5)

Rev 30.0/5-13 3 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" [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: 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 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 = 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 ISPOSAL OF
THE L IFTER after its service life, see INTENDED USE.
ASME Standard BTH-1: Design Category "B", Service Class "0" (see www.powrgrip.com for more information)
!!-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.
