SPECIFICATIONS
Description:
Designed for use with a crane or other hoisting equipment, P21104-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:
P2110445DCO
P211047DCO
P2HV110445DCO
P2HV11047DCO
Vacuum Pads:
(Eight,
standard
rubber, with #60 filter screen)
11" [28 cm] nominal diameter, lipped
(Model G3370)
10" [25 cm] nominal diameter, lipped
(Model HV11

)
Maximum Pad Spread:
51" x 54¼"
51" x 84¼"
50" x 53¼"
50" x 83¼"
(to outer edges)
[1295 x 1378 mm]
[1295 x 2140 mm] [1270 x 1353 mm] [1270 x 2115 mm]
Lifter Weight:
177 lbs [81 kg]
190 lbs [87 kg]
181 lbs [82 kg]
194 lbs [88 kg]
Load Capacity:
(rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces)

Per-Pad:
175 lbs [79.5 kg]
150 lbs [68 kg]
Maximum:
1400 lbs [635 kg]
1200 lbs [545 kg]
Power Source:
12 volts DC, 10 amps (with Thomas pump) or 3 amps (with Dynaflo pump) for each
pad channel
Battery Capacity:
7 amp-hours
Rotation Capability:
Manual, 180°, with automatic locking at each ¼ revolution (when desired)
Tilt Capability:
Manual, 90°, with automatic locking in vertical position
Vacuum Pumps:
Diaphragm type, 1 SCFM [28 liters/minute] nominal airflow
Vacuum Reserve Tanks: 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:
Dial gauges indicate current vacuum level in positive inches of Hg and negative kPa.
Low Vacuum Warning
Lights and Buzzers:
Red lights and audio buzzers are energized until vacuum level is sufficient to lift
maximum load weight (higher than 16" Hg [-54 kPa]) and whenever vacuum loss
causes pumps to re-engage. See appendix for warning buzzer instructions.
Options:
Model EO10DVS - Dual Vacuum System. Each vacuum system features two vacuum
line circuits, which allows 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).
See separate instructions about other options.
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.
