three-winding stop alarm / automatic stop device, load indicator, hydraulic safety valve, hydraulic
automatic locking device, slinging rope detachment protector, alarm buzzer, audio alarm, level, crane
tip-over alarm (an alarm issued in the event of the crane operation at 3-degree inclination and traveling at
15-degree inclination), traveling lever lock, traveling/crane/outrigger selector switch (designed to prevent
the machine from craning at traveling), outrigger safety device (outrigger interlock and crane interlock),
moment limiter (working envelope limited), working status lamp, outrigger non-installation warning lamp.
3.3 MACHINE FUNCTIONS
[1] TRAVELING DOLLY
• This is a compact machine designed to keep the overall width between the crane and outrigger
minimized with them housed (in traveling position).
This compact design is ideal for work in confined areas.
• Two-traveling lever operation enables not only direction changes among forward, backward, and
right/left but pivot turn and spin turn.
[2] CRANE
• An automatic slide outrigger is embedded in the crane to permit outrigger extension and grounding from
the operation seat.
• Through the combined use of telescoping, derricking, and slewing besides winch system operation, the
crane is capable of raising or lowering the hook block and moving an object weighing within the rated
total load to a designated position within the confines of the working envelope.
• Remote-control units allow remote outrigger setting and remote crane operation.
