Wood’s Powr-Grip MRTALPCH611LDC - Manual (Page 5)

Rev 8.0/6-13 3 MRTALPCH6-DC: #35054
SPECIFICATIONS
Description: Designed for use with a crane or other hoisting equipment, MRTALPCH6-DC lifters employ vacuum to hold
a load for lifting, and they provide manual 180° rotation and manual 90° tilt movements for load
manipulation.
Model Number: MRTALPCH611LDC MRTALPCH6HV11DCO MRTALPCH610DCO
Vacuum Pads: 1 (Six of standard rubber, spring-mounted with 1/8" [3 mm] travel and #60 filter screen)
11" [28 cm] nom. diameter,
lipped (Model G3370)
10" [25 cm] nom. diameter,
lipped (Model HV11)
10" [25 cm] nom. diameter,
concave (Model G0750)
Pad Spread: (to outer edges)
Minimum: 53¾" x 12" [1365 x 305 mm] 52¾" x 11" [1340 x 279 mm] 51¾" x 10" [1314 x 254 mm]
Maximum: 79¼" x 12" [2010 x 305 mm] 78¼" x 11" [1988 x 279 mm] 77¼" x 10" [1962 x 254 mm]
Load Capacity: (rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces 2 )
Per-Pad: 184 lbs [83.5 kg] 150 lbs [68 kg] 150 lbs [68 kg]
Maximum w/4 pads: 700 lbs [320 kg] 600 lbs [270 kg] 600 lbs [270 kg]
Maximum w/6 pads: 1100 lbs [500 kg] 900 lbs [410 kg] 900 lbs [410 kg]
Lifter Weight: 125 lbs [57 kg] 131 lbs [60 kg] 118 lbs [54 kg]
Power Source: 12 volts DC, 10 amps (with Thomas pump) or 3 amps (with Dynaflo pump)
Battery Capacity: 7 amp-hours
Tilt Capability: Manual, 90°, with mechanical advantage that minimizes operator effort and automatic latching in upright
position
Rotation Capability: Manual, 180°, with automatic latching at each ¼ revolution (when desired)
Vacuum Pump: Diaphragm type, 1 SCFM [28 liters/minute] nominal airflow
Dual Vacuum System: 2 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).
Vacuum Reserve Tanks: 2 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: 2 dial gauges indicate current vacuum level in positive inches of Hg and negative kPa.
Vacuum Lift Light: Green light is energized whenever vacuum is higher than the level required to lift the maximum load weight
(16" [-54 kPa]).
Low Vacuum Warning Buzzer: Maximum 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 EO8RC1 - Remote Control System. This option features a radio transmitter and
receiver that can activate apply and release functions at distances up to 250 ft [76 m]. The system uses
either a 310-320 or a 433-434 MHz signal, depending on requirements in your geographical location.
See separate instructions about other options.
Operating Elevation: Maximum = 6000 ft [1828 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.
