Wood’s Powr-Grip MT1HV11DC - Manual (Page 5)

Rev 10.5/4-14 3 MT1/2HV11DC: #35081
SPECIFICATIONS
Description: Designed for use with a crane or other hoisting equipment, these lifters employ
vacuum to hold a load for lifting, and they provide manual 90° tilt movement for
load manipulation.
Model Number: MT1HV11DC (w/1 pad) MT2HV11DC (w/2 pads)
Pad Spread: (to outer edges) 11" x 11" [279 x 279 mm] 11" x 23½" [279 x 597 mm]
Load Capacity: (rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces 1 )
Maximum: 150 lbs [70 kg] 300 lbs [135 kg]
Per-Pad: 150 lbs [70 kg] 150 lbs [68 kg]
Lifter Weight: 36 lbs [17 kg] 52 lbs [24 kg]
Power Source: 12 volts DC, 10 amps (with Thomas pump) or 3 amps (with Dynaflo pump)
Battery Capacity: 7 amp-hours
Vacuum Pads: 10" [25 cm] nominal diameter, lipped (Model HV11), standard rubber, spring-
mounted (¼" [7 mm] travel), with #60 filter screen; Optional closed-cell foam rings
for applications on rough or textured surfaces.
Tilt Capability: Manual, 90°
Vacuum Pump: Diaphragm type, 1 SCFM [28 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.
Low Vacuum Warning Light: Red light is energized until vacuum level is sufficient to lift maximum load weight
(higher than 16" Hg [-54 kPa]) and whenever vacuum loss causes pump to re-
engage.
Low Vacuum Warning
Buzzer:
Maximum Alarm Volume = 103 dBA at 2 ft [60 cm]. While lifter is powered up,
audible alarm warns the operator whenever vacuum is not sufficient for lifting the
maximum load weight.
Options: See separate instructions about optional features.
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
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

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.
