RT9130E-2 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
Lowering and Raising the Hoist Cable
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 Auxiliary Hoist Control Lever forward, away
from the operator, and hold until the hook or load is lowered
to the desired height.
Raising the Cable
Pull the Main or Auxiliary Hoist Control Lever back, toward
the operator, and hold until the hook or load is raised to the
desired height.
Hoist Speed Range Selection
To change the speed range of the hoist(s), position the
applicable switch (Main Hoist Speed or optional Auxiliary
Hoist Speed) to High or Low as applicable
Raising and Lowering the Hydraulic Jib
The normal operating range for lifting loads with the
hydraulic jib is an extension offset of 5 - 40 degrees. The jib
must be retracted to 0 degree offset for stowage on the side
of the boom.
The hydraulic luffing jib is controlled by two switches on the
left hand seat armrest. The jib is controlled by an On/Off
switch and a Raise/Lower Switch. See Control Seat
Assembly - Single Axis, page 3-17 for location and
description of these switches.
The jib may also be controlled by two remote stations on the
jib (Figure 3-22). The first station is located on the jib adapter
section, while the second station is located at the head of the
jib base section.
Raising the Hydraulic Jib
The Luffing Jib On/Off Switch must be in the On position.
Push the Luffing Jib Raise/Lower Switch to the Raise
position and hold until the jib is raised to the desired position
or a switch-off point is reached.
DANGER
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.
CAUTION
Do not change the hoist speed range with the hoist
rotating.
