WOOD'S POWR-GRIP MRTALP Series, Instructions Manual, Page: 5 / 46

Rev 12.3/1-17 3 MRTALP6-DC: #35056
SPECIFICATIONS
Power Source: 12 volts DC, 5 amps
Battery Capacity: 7 amp-hours (18 amp-hours standard for MRTALP6FS10TDC, optional for others)
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 every 30° of revolution (when desired)
Vacuum Pump: Diaphragm type, 2.5 SCFM [71 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 when 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 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 a 310-320 MHz
signal.
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 D

Description: Designed for use with a crane or other hoisting equipment, the MRTALP6-DC lifters employ vacuum to hold
a load for lifting, and they provide manual 180° rotation and mechanically assisted, manual 90° tilt
movements for load manipulation.
