3. GENERAL
3.2 CHARACTERISTICS OF THE MACHINE
• It is possible to reduce the cost for maintenance through imporved working
performance and less usage of contactors as SEM(Separately Excited Motor) type
travel motor is used.
• Excellent working performance by installing high-output and high-efficient motor, and
geatly improved durability by installing Traveling and hydraulic motor with H type
of insulating class.
• The position and descriptions of the troubles are displayed in characters and codes
at the same time by using various self-diagnostic functions, which make the process
of maintenance and inspection simple. The controller can limit and reduce the
functions automatically according to the condition of troubles to improve machine
safety.
• The complex control function of travel and hydraulic prevents the instant over
discharging in order to achieve the maximization of service time.
• Suspension system with impact absorption springs is installed in order to reduce
operator’s fatigue and to improve durability of machine.
• Big LCD display panel with high brightness is installed in order to check almost
all contents related to the machine conditions.
• Operators can fix a certain speed in advance, and can travel under static speed
traveling mode in order to carry the important load safely.
• The working performance of mast is improved by increasing free lift height with
helps of free bar system.
