SPECIFICATIONS

MRTA611LDC
Designed for use with a crane or other hoisting equipment, the MRTA611LDC lifter employs
vacuum to hold a load for lifting, and it provides manual 360° rotation and mechanically assisted,
manual 90° tilt movements for load manipulation.
12 volts DC, 8 amps

Manual, 90°, with four-bar tilt linkage that minimizes operator effort and automatically holds a
correctly attached load in the upright or flat position.
Manual, 360°, with automatic latching (when desired).
Diaphragm type, 1 SCFM [28 liters/minute] nominal airflow
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).
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.
Two dial gauges indicate current vacuum level in positive inches of Hg and negative kPa.
maximum load weight (higher than 16" Hg [-54 kPa]) and whenever vacuum loss causes pump to
re-engage. See appendix for warning buzzer instructions.
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.
Maximum = 6000 feet [1828 meters]

This lifter is designed to have a service life of at least 20,000 lifting cycles, when used as
intended.
