Wood’s Powr-Grip P11104AC - Manual (Page 3)

Rev 10.0/6-12 1 P1-AC: #35110
SPECIFICATIONS
Description: Designed for use with a crane or other hoisting equipment, P1-04AC lifters employ vacuum
to hold a load for lifting, and they provide manual 180° rotation and manual 90° tilt
movements for load manipulation.

(to outer edges) [1245 mm x 254 mm] [1270 mm x 280 mm] [1295 mm x 305 mm]
Load Capacity: (rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces 2 )
Per-Pad: 150 lbs [68 kg] 150 lbs [68 kg] 175 lbs [80 kg]
Maximum: 600 lbs [270 kg] 600 lbs [270 kg] 700 lbs [320 kg]
Lifter Weight: 70 lbs [32 kg] 79 lbs [36 kg] 75 lbs [34 kg]
Power Source: See serial number plate for specific AC voltage, frequency and amperage.
Rotation Capability: Manual, 180°, with automatic locking at each ¼ revolution (when desired)
Tilt Capability: Manual, 90°, with automatic locking in vertical position
Vacuum Pump: Rotary Vane Type, 2.5 SCFM [71 liters/minute] nominal airflow
Vacuum Reserve Tank: Vacuum reservoir helps prevent immediate vacuum loss in case of power failure.
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]).
Options: See separate instructions about optional features.
Operating Elevation: Maximum = 8000 feet [2438 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
information)
