RT600E OPERATOR MANUAL
Lowering And Raising The Hoist Cable (Single Axis
Controller Option)
WARNING
Keep the area beneath the load clear of all obstructions
and personnel when lowering or raising the cable (load).
Do not jerk the control lever when starting or stopping the
hoist. Jerking the lever causes the load to bounce, which
could result in possible damage to the crane.
NOTE: When the load is stopped at the desired height, the
automatic brake will engage and hold the load as
long as the control lever remains in neutral.
Lowering The Cable
Push the MAIN or AUX HOIST control lever forward, away
from yourself, and hold until the hook or load is lowered to
the desired height.
Raising The Cable
Pull the MAIN or AUX HOIST control lever back, toward
yourself, and hold until the hook or load is raised to the
desired height.
Hoist Speed Range Selection (Single Axis Controller
Option)
CAUTION
Do not change the hoist speed range with the hoist
rotating.
To change the speed range of the hoist, position the
applicable switch (MAIN HOIST SPEED or optional AUX
HOIST SPEED) to HIGH or LOW as applicable.
Swinging the Boom (Dual Axis Controller Option)
DANGER
Death or serious injury could result from being crushed by
moving machinery. Before activating swing, sound the
steering wheel horn and verify that all personnel are clear
of rotating and moving parts.
WARNING
Keep the area beneath the boom clear of all obstructions
and personnel when lowering the boom.

OPERATING CONTROLS AND PROCEDURES
The operator must select the proper load chart and RCL
program for the outrigger position selected.
Never push or pull the swing control lever through neutral
to the opposite direction to stop swing motion. Use the
swing brake foot pedal to stop swing rotation.
NOTE:
To swing the boom, push the controller on the left hand
armrest to the right for right swing (rotates turntable
clockwise), or to the left for left swing (rotates turntable
counterclockwise). Always operate the control lever with a
slow, even pressure. Use the swing brake foot pedal to stop
rotation, then position the SWING BRAKE switch to ON to
prevent further rotation.
Elevating the Boom (Dual Axis Controller Option)
Keep the area above and below the boom clear of all
obstructions and personnel when elevating the boom.
To elevate the boom, push the controller on the right hand
armrest to the left (raises the boom), and hold until the boom
reaches the desired elevation.
Lowering the Boom (Dual Axis Controller Option)
Keep the area beneath the boom clear of all obstructions
and personnel when lowering the boom.
Long cantilever booms can create a tipping condition,
even when unloaded and in an extended, lowered
position.
When lowering the boom, simultaneously let out the hoist
cable to prevent two-blocking the boom nose and hook
block.
The closer the load is carried to the boom nose, the more
important it becomes to simultaneously let out the hoist
cable as the boom is lowered.
To lower the boom, push the controller on the right hand
armrest to the right (lowers the boom) and hold until the
boom is lowered to the desired position.
