Stowing And Parking; Unattended Crane - Manitowoc Grove RT765E-2 Operator's Manual

RT765E-2 OPERATOR MANUAL
WARNING
Risk of Unexpected Operation!
There are no machine 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 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 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 (located in the directional control valves)
which are in series 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.

Stowing and Parking

Tipping Hazard!
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.
