New pressure-compensated CLSS
hydraulic system HydrauMind
Even when 2 or more actuators are
operated simultaneously, the PC58UU-3's
pressure-compensated CLSS system
ensures that each actuator works
according to its control input without
affecting the size of the load. This gives
the operator precise control at all times.
Engine speed sensing=Optimum Power
Power utilized by main pump is adjusted automatically in accordance with the engine speed.
That means this computerized system keeps
engine speed even under high load condition.
Back fill blade
The PC58UU features a standard
back fill blade that can quickly
and conveniently fill trenches and
clear up jobsites.

lifting capacity
Powerful digging force
Digital Depth Display
Ditching, trenching, or digging is even more efficient
with this automatic depth measurement system.
Informing the operator of dig depth from ground level
(absolute depth) and the depth from any pre-set point
(relative depth) enables work to go much more
smoothly and efficiently. This lessens the need for the
operator to stop operation or leave the cab after each
adjustment, which also increases productivity.
Height Limiter
An adjustable boom height limiter can be set prior to
operation. When the boom reaches the pre-set height
limit, an alarm will sound and the boom automatically
stops. This function can help increase productivity by
letting operators focus more on digging in tight or
confined spaces.

Bucket interference prevention system
The bucket automatically stops itself from contact with
the cab/canopy. During operation, an alarm sounds and
the equipment is stopped if
the bucket gets too close to
contact. This feature helps
maintain operator confidence,
which can increase
productivity.

Control Pattern change Valve (optional)
Whether you are
comfortable with ISO or
SAE control patterns, you
can easily and consciously
change from one to the
other.
The track frame is sloped so
that dirt will not be accumulate
and can be removed easily.
Larger opening reduces fuel

ROADLINER
Rubber thickness has been upgraded using
a new type of core bar, and this section that
is often sheared has been reinforced.
Reinforced type
Ideal performance has been achieved with combining the merits
of rubber and the strengths of steel in the new Road Liner shoes.
Road Liners can last up to twice as long as rubber tracks under
most normal operating conditions.
Similar to all rubber tracks, pavement is not easily damaged.
Replacement is fast and easy.
Wide-ranging cost reductions are
possible by replacing only the
damaged or worn-out shoes,
which differs from the need to
replace a full rubber or steel
track.
