MACHINE FEATURES
This machine is only to be used for crane
operation.
This machine is a mobile crane with a rubber track
travelling dolly (carrier) mounted with a boom
crane.
This self-propelled crane is capable of moving
(travelling) on a worksite and craning an object
weighing within the rated total load capacity. This
crane can be operated with a radio remote control
system.
Main Features
Viewed from the travel lever, the front, back, left
and right of the machine are illustrated in this
manual from the front of the machine. Boom
slewing motion is determined with the machine
viewed from directly above; slew clockwise (right)
denotes right-handed motion and slew
counterclockwise (left) denotes left-handed
motion.
The main components of this machine are the
travelling dolly and crane.
Travelling Dolly
The travelling dolly is composed of a travelling
gear, battery unit, travelling operation unit and
crane operation unit.
This machine is compact in design in order to
keep the overall width between the crane and
outrigger minimised while housed (in travelling
position). This compact design is ideal for work in
confined areas.
Two-travel lever operation enables direction
changes forward, backward and right/left, and
also pivot and spin turns.
A battery is provided to allow operation without
exhaust gas emissions.
Crane
The crane is composed of a telescoping system,
boom system, hook block, winch system and
outrigger system.
Through the combined use of telescoping, boom
slewing and winch operation, the crane is capable
of raising or lowering the hook block and moving
an object weighing within the rated total load
capacity to a designated position within the
confines of the working area.
A radio remote control system allows remote
crane operation.
