Heavy Lift Mode

Gives the operator 10% more lifting force on the boom
when needed for handling rock or heavy lifting applications.

Two Settings for the Boom

Smooth mode provides easy operation for gathering blasted rock and

scraping operations. When maximum digging force is needed, switch to

power mode for more effective excavating.

Power Max Function

This function temporarily increases digging force by 8% for added power in
tough situations.

Excellent Underfoot Digging Performance

The operability of the underfoot area, just below the operators cab, is
excellent. This makes grading, leveling, rolling, carrying, and scraping soil
in the underfoot area easy.

Automatic Two-Speed Travel

Travel speed automatically shifted from high to low speed according to the
pressure of travel.

Working Mode Application Advantage

Mode ● Fast cycle times

E

Economy

● Good cycle times

Mode ● Good fuel economy

Hydraulics

Unique two-pump system assures smooth compound movement of the
work equipment. OLSS (Open Center Load Sensing System) controls all
pumps for efficient engine power use. This system also reduces hydraulic
loss during operation.

Active and Economy mode

The PC600-7 excavator is equipped with two working modes. Each mode
is designed to match engine speed, pump speed, and system pressure to
the current application, giving the operator flexibility to match equipment
performance to the job at hand.
