Explanation
This is a function that releases the brake when
the tires skid (tires are not rotated). This function
applies the brake again when the tires rotate.
This is a function that automatically sets the idle
speed.
This is a function that performs the steering oper-
ations with a lever instead of using a steering
wheel. This function performs gear shifting and
changing forward and reverse direction.
This is a function that automatically operates the
retarder with a constant braking force when let-
ting go of the accelerator pedal on the downhill.
This is a function that automatically operates the
retarder to ensure that the machine speed does
not accelerate above the speed set by the opera-
tor when letting go of the accelerator pedal on
the downhill.
This is a function that drives both wheels auto-
matically using the optimum braking force when
the tire on one side spins on the soft ground sur-
faces.
A function or component that can be added to the
standard specification.
This is a valve that bypasses a part of the brake
cooling oil to reduce the load applied to the hy-
draulic pump when the retarder is not being
used.
This is one of communication standards that are
used in the network on the machine.
This is a regulator valve that is installed to KCCV
ventilator. It is written as CDR valve and is not
used independently.
This is a system that can actuate multiple actua-
tors simultaneously regardless of the load (pro-
vides better combined operation than OLSS).
