Wood’s Powr-Grip MT89AC - Manual (Page 5)

Rev 14.0/6-14 3 MT89AC: #35088
SPECIFICATIONS
Model Number: MT89AC
Description: Designed for use with a crane or other hoisting equipment, the MT89AC
lifter employs vacuum to hold a load for lifting, and it provides manual 90°
tilt movement for load manipulation.
Power Source: See serial number plate for specific AC voltage, frequency and amperage.
Vacuum Pads: Eight 9" [23 cm] nominal diameter (Model VPFS9), standard rubber, spring-
mounted (¼" [7 mm] travel), with #60 filter screen
Pad Spread: 49¼" x 99¼" [1248 mm x 2518 mm] to outer edges
Maximum Load Capacity: 1000 lbs [455 kg] based on Per-Pad Load Capacity of 125 lbs [57 kg],
rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces 1
Lifter Weight: 183 lbs [83 kg]
Tilt Capability: Manual, 90°; Latch engages when pad frame is in vertical orientation.
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 Lights: Green lights are 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
