Specification of PC200-7 ( BASIC SPEC and FULL DELUXE SPEC )

For the PC200-7 series, Excel spec is discontinued then Basic spec and Full Deluxe spec are newly itroduced. Basic spec means that the machine has basic functions of the PC200-7 and Full Deluxe spec can be made by adding and changing the following deluxe items. The machine structure and control systems of Basic spec and Full Deluxe spec is basically the same and the deluxe items for Full Deluxe spec are provided as optional items.

(20 degree uphill; km/h, Hi/Lo)

<Comparison of travel speed at small steering angle>In the travel of Hi range, the travel speed is fast at small steering, and the travel speed does not decrease much.In sensory evaluation, steering is very smooth.

<Comparison of uphill traveling speed> The traveling speed reduces very little when traveling up 20-degree hills, and this reduction compares favorably with competing machines

Automatic Speed Change Function

This function selects Hi and Lo travels atideal points depending on workloads

Adoption of travel junction valve and increase of engine horsepower have improved thetraveling performance

Common

When same amounts of oil flow to the both right and left travel motors through the travel junction circuit, the straight travel performance is improved.

When the travel junction circuit is closed and oil flows to the right and left travel motors separately, the oil flows from the pump are controlled with the travel lever for smooth turning

When the travel junction circuit opens and same amounts of oil flow from one pump to the both right and left travel motors constantly, the work equipment can operate while the machine travels

Adopting travel junction valve in control valve improves straight travel performance, steeringperformance and ability to travel up hills at the same time.

Fully automatic air conditioner for cooling and heating. Its bi-level control function keeps operator's head cool and feet warm by controlling airflow and maintains the cab comfortable throughout a year.

The very tightly closed pressurized cab prevents dusts from entering the cab even in a dusty environment. The internal pressure + 6mmAq is realized by closing the cab very tight when the air conditioner is operated (in the external air introduction mode). Dusts are prevented from entering the cab

A washable floor mat with flange is used in the cab. The cab door side is gently inclined for easy draining. Also, a drain hole is provided on the front side under the mat for perfect draining.
