VL411LDC
Designed for use with a crane or other hoisting equipment, the VL411LDC
lifter employs vacuum to hold a load for lifting in the upright orientation.
12 volts DC, 10 amps (with Thomas pump) or 3
.5
amps (with Dynaflo pump)
7 amp-hours
Four 11" [28 cm] nominal diameter, lipped (Model G3370), standard rubber,
spring-mounted (¼" [7 mm] travel), with #60 filter screen
23½" x 58" [597 mm x 1474 mm] to outer edges
(rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces
1
)
175 lbs [80 kg]
700 lbs [320 kg]
65 lbs [30 kg]
Diaphragm type, 1 SCFM [28 liters/minute] nominal airflow
Vacuum reservoir helps prevent immediate vacuum loss in case of power
failure and extends battery life by reducing pump cycles required to maintain
vacuum.
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 (if applicable): Maximum Alarm Volume = 103 dBA at 2' [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 = 6,000' [1,828 m]
Operating Temperatures: 32° to 104° F [0° to 40° C]
Service Life:
This lifter is designed to have a service life of 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
