PT410AC: #35140
SPECIFICATIONS
Model Number:
PT410AC
Description:
Designed for use with a crane or other hoisting equipment, the PT410AC lifter
employs vacuum to hold a load for lifting, and it provides powered 90° tilt
movement for load manipulation.
Power Source:
See serial number plate for specific AC voltage, frequency and amperage.
Vacuum Pads:
Four 10" [25 cm] nominal diameter, concave (Model G0750), standard rubber,
spring-mounted (approx. 1" [2.5 cm] travel), with #60 filter screen
Pad Spread:
17" x 45½" [433 mm x 1157 mm] to outer edges
Load Capacity:
(rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces
1
)
Per-Pad
125 lbs [56.5 kg]
Maximum
500 lbs [225 kg]
Lifter Weight:
154 lbs [70 kg]
Tilt Capability:
Powered, 90°; Speed = approx. 6.5 seconds; Duty = 81 tilts per hour
Vacuum Pump:
Rotary vane type, 4 SCFM [113 liters/minute] nominal airflow
or
Diaphragm type, 3 SCFM [85 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.
Vacuum Lift Light:
Green light is energized whenever vacuum level is sufficient for lifting
maximum load weight (higher than 16" [-54 kPa]).
Options:
See separate instructions about optional features.

Maximum = 10,000 feet [3048 meters]
Operating Temperatures: 32° to 100° F [0° to 38° 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
