MRTA6-DC: #35072
SPECIFICATIONS
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. When engaged, tilt locks ensure that the orientation of the
load is not compromised by accidental or unexpected forces.
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:
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:
Maximum Alarm Volume = 103 dBA at 2 ft [60 cm]. While the lifter is powered up, an 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 = 6000 ft [1828 m]
Operating Temperatures:
32° to 104° F [0° to 40° 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

Description:
Designed for use with a crane or other hoisting equipment, the MRTA6-DC lifters employ vacuum to hold a
load for lifting, and they provide manual 360° rotation and mechanically assisted, manual 90° tilt
movements for load manipulation.
