RT9130E-2 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
Work Area Definition allows the crane operator to describe
the crane’s working area by setting up “virtual walls”. They
are referred to as virtual walls because they exist in the
system and are not real walls. The virtual walls represent
obstacles (i.e. buildings, towers, poles, etc.) in the crane’s
working range. They are set by defining points along the
outer limits of the working area with the tip of the boom. Once
the working area has been defined, the system will provide a
visual and an audible warning if the boom approaches a
virtual wall.
An Anti-Two Block Device is also incorporated into the
system to prevent the hook block or headache ball from
coming into contact with the boom nose or jib. This condition
will also cause a lockout of hoist up, boom down, and
telescope out, and also provide a visual and an audible
alarm.
Refer to the rated capacity limiter (RCL) Operator Manual for
more detailed information on the function of the RCL system.
Control Lever Lockout System
The control lever lockout system consists of hydraulic
solenoid valves (located in the directional control valves)
which are in series between the hydraulic remote control
valves (joysticks) in the cab and the pilot-operated
directional control valves. When the valves are actuated,
they prevent pilot flow between the hydraulic remote control
valve in the cab and the appropriate directional control valve.
The valves are activated in such a manner as to prevent
worsening the condition, i.e. boom down, telescope out, or
hoist up. The control lever lockout system is used with the
anti-two-block system or the Rated Capacity Limiter (RCL)
System.
STOWING AND PARKING
When parking the crane, do the following:
1. Park the crane on a stable surface.
2. Remove the load from the hook.
3. Stow the swingaway jib, if erected.
4. Fully retract the boom and position it in the normal travel
position.
5. Engage the swing brake and/or swing lock pin.
6. Retract all jack cylinders and outrigger beams.
7. Apply the parking brake.
8. Put all operating controls in the neutral position.
9. Position the Crane Function Switch to OFF.
10. Shut down the engine following the proper procedures
specified in this manual and the applicable engine
manual.
11. Remove the keys.
12. Close and lock all windows, covers, and doors.
13. Turn Battery Disconnect (1, Figure 3-23) to Off position if
machine will be inactive for over 24 hours.
WARNING
Boom Collision Hazard!
There are no cutouts associated with the swing angle set
limitation or the work area definition features.
CAUTION
When defining virtual wall(s), always allow a safe working
distance to any obstacles. Never work outside a safe
working area as defined by common practice, standards,
and manuals.
DANGER
Never park the crane near holes, or on rocky or extremely
soft surfaces. This may cause the crane to overturn,
resulting in injury to personnel.
CAUTION
Avoid Crane Damage!
Do not engage the parking brake while the vehicle is
moving. Damage to the crane can occur.
Disengage the parking brake before driving. Damage to
the crane can occur.
CAUTION
Risk of Undesirable Operation!
To avoid possible engine fault codes and undesirable
operation, ensure the keyswitch has been off two minutes
before disconnecting the batteries.
Disconnect batteries, if machine will be inactive for over
24 hours.
