3.3 MACHINE FUNCTIONS
[1] CARRIER
• This machine is designed to have a compact overall width when the crane and outriggers are
stowed (traveling posture), which facilitates running in confined areas.
• Use of the two operation levers enables not only travel direction changes (forward, backward,
rightward and leftward) but also pivot turns and spin turns.
• By using the radio controller, it is possible to remotely control the movement of travel.
[2] CRANE
• This crane is equipped with automatic slide outriggers which enable the operator to extend and
set outriggers while seated on the driver's seat.
• Through the combination use of the telescopic boom, derricking and slewing systems besides
the winch system, the crane can raise and lower the hook block to move the lifted object to the
desired position within the rated total load and the specified working envelope.
• The outrigger setup and the crane operations can also be performed with the remote control
system.
