Wood’s Powr-Grip FL4HV11AC - Manual (Page 5)

Rev 15.0/1-14 3 FL4HV11AC: #35030
SPECIFICATIONS
Model Number: FL4HV11AC
Description: Designed for use with a crane or other hoisting equipment, the FL4HV11AC lifter
employs vacuum to hold a load for lifting in the flat orientation.
Power Source: See serial number plate for specific AC voltage, frequency and amperage.
Vacuum Pads: 1 Four 10" [25 cm] nominal diameter, lipped (Model HV11), standard rubber, spring-
mounted (¾" [20 mm] travel), with #60 filter screen
Pads Shutoff: Manual valve controls vacuum flow at outermost pads.
Pad Spread: (to outer edges)
Minimum: 11" x 30" [279 mm x 762 mm] w/arms folded up
Maximum: 11" x 60" [279 mm x 1524 mm] w/arms folded down
Load Capacity: (rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces 2 )
Per-Pad: 250 lbs [114 kg]
Maximum (w/2 pads): 500 lbs [228 kg]
Maximum (w/4 pads): 1000 lbs [455 kg]
Lifter Weight: 86 lbs [39 kg]
Vacuum Pump: 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" Hg [-54 kPa]).
Options: See separate instructions about optional features.
Operating Elevation: 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 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
