PERATION
Safe Operation with Small Tail Swing Even in Confined Areas
Short Implement Swing Radius:
1980 mm 6'6" boom raising angle of
the PC138US-8 is larger than a
conventional profile excavator. The
result is reduced front implement
swing radius.

Roadwork
When performing roadwork, protrusion of the machine into the
unoccupied lane is kept minimal since the rear portion of the
upper structure protrudes slightly from the track at swing. This
allows a dump truck to be positioned closer to the track of the
machine. The operator is able to load materials efficiently onto
the front of the dump body at ease since ample dumping reach
is assured for the loading. Large working space is not required
for the machine.

Logging and forest roadwork
Since the protrusion of the rear portion of the upper
structure is kept minimal, there is less possibility of the
counterweight hitting against a
tree or a slope, allowing the
operator to operate the
machine at ease. Furthermore,
large digging height facilitates
slope finishing work. Large
drawbar pull assures
smooth and powerful
traveling even on rough

terrain.
Demolition
The machine needs less working space and can perform
efficient demolition work since it has large and ample
digging height.

Wider Working Ranges
Raising the boom on the PC138US-8 to a wider
angle enhances overall working performance.
Job sites that require a long upper reach, such as
demolition and slope cutting, also benefit from the
increased digging and dumping ranges of the
PC138US-8.

Round Profile of both Front and Rear Portion of the
Upper Structure
Komatsu hydraulic excavators with small tail swing radius design
adopt the round profile for both left and right corners of the front
portion of the upper structure as well as its rear portion that features
less protrusion from the track at swing. The round profile design
allows the machine to work in tight quarters.
