OPERATING CONTROLS AND PROCEDURES
TMS800E13 OPERATOR MANUAL
3-52
Published 02-06-2014, Control # 495-00
Raising the Cable
Pull the main hoist (right hand armrest) or auxiliary hoist (left
hand armrest) joystick, 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), press the top
(high speed) or bottom (low speed) of the main hoist speed
switch located on the right hand armrest or auxiliary hoist
speed switch located on the left hand armrest.
Operational Aids
Rated Capacity Limiter (RCL) System
The RCL is an electro-mechanical sensing system designed
to alert the crane operator of impending capacity when the
system has been properly preset by the operator. The control
panel is mounted in the front console of the operator’s cab.
When an overload condition is sensed, the system provides
the operator with a visual and audible warning, and locks out
the control levers to prevent lowering the boom, extending
the boom, or raising the main or auxiliary hoist cables.
Three additional features are included within the RCL
system:
•
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.
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 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 located in the directional control valves. The
valves are activated in such a manner as to prevent
worsening the condition, that is, 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. The RCL sends a signal to the CAN bus system
which turns off the solenoids on the directional valves.
WARNING
Do not change the hoist speed range with the hoist
rotating.
DANGER
Electronic equipment on this crane is intended as an aid
to the operator. Under no condition should it be relied
upon to replace the use of capacity charts and operating
instructions. Sole reliance upon these electronic aids in
place of good operating practices can cause an accident.
CAUTION
When defining virtual walls 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 cut-outs associated with the swing angle set
limitation or the work area definition features.
