Control Lever Lockout System; Stowing And Parking; Unattended Crane - Manitowoc Grove RT600E Operator's Manual

RT600E OPERATOR MANUAL
• Swing Angle Set Limitation
• Work Area Definition
• Anti-two Block Device
Swing Angle Set Limitation allows left and right swing
angle to be preset. When the preset angle is reached, the
system will provide an audible warning.
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.
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.
WARNING
There are no cutouts associated with the swing angle set
limitation or the work area definition features.
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 boom extension.
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 RCL Operator's Handbook 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 placed in-line between the hydraulic remote
control valves 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.

OPERATING CONTROLS AND PROCEDURES

Stowing And Parking

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.
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 boom extension, 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 Handbook and the applicable Engine
manual.
11. Remove the keys.
To avoid possible engine fault codes and undesirable
operation, ensure the keyswitch has been off 2 minutes
before disconnecting batteries.
12. Disconnect batteries, if machine will be inactive for over
24 hours.
13. Close and lock all windows, covers, and doors.

Unattended Crane

Changing weather conditions including but not limited to:
wind, ice accumulation, precipitation, flooding, lightning,
etc. should be considered when determining the location
and configuration of a crane when it is to be left
unattended.
Failure to comply with these instructions may cause death
or serious injury.
The configuration in which the crane should be left while
unattended shall be determined by a qualified, designated
individual familiar with the job site, configuration, conditions,
and limitations.
