Rev 3.0/10-06
QUADRA-TILT ROTATOR • DC-VOLTAGE
Page 1
SPECIFICATIONS
Lifter Weight:
188 lbs [86 kg]
Tilt Capability:
Manual, 90°, with four-bar tilt linkage that minimizes operator effort and automatically holds a
correctly attached load in the upright or flat position.
Rotation Capability:
Manual, 360°, with automatic latching (when desired).
Vacuum Pump:
Diaphragm type, 1 SCFM [28 liters/minute] nominal airflow
Dual Vacuum System:
Two vacuum system circuits allow 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).
Vacuum Reserve Tanks:
Two 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:
Two dial gauges indicate current vacuum level in positive inches of Hg and negative kPa.
Low Vacuum Warning Light and Buzzer: Red light and audio buzzer are 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. See appendix for warning buzzer instructions.
Options:
Available
with Model LB8TLO - Tilt Locks. When engaged, this option ensures that the upright or
flat orientation of the load is not compromised by accidental or unexpected forces.
See appendix for instructions about other options.
Operating Elevation:
Maximum = 6000 feet [1828 meters]
Operating Temperatures: 15° to 105° F [-9° to 40° C]
Service Life:
This lifter is designed to have a service life of at least 20,000 lifting cycles, when used as
intended.
Wiring Diagram:
The following wiring diagram is attached for reference in servicing the lifter or trouble-shooting a
deficiency: D705E-W01 [E-W01]
