Efficient Hydraulic System
The mid-size excavator uses a Closed Center Load Sensing (CLSS) hydraulic system that improves fuel efficiency and provides quick response to the operator's demands. It also introduces new technology to enhance the engine and hydraulic pump control. This total control system matches the engine and hydraulics at the most efficient point under any load condition. There have also been improvements in the main valve and hydraulic circuit to reduce hydraulic loss, resulting in higher efficiency and lower fuel consumption.
Working Mode Selection
The mid-size excavator is equipped with six working modes (P, E, L, B, ATT/P and ATT/E). Each mode is designed to match engine speed, pump flow, and system pressure to the application. It features a new mode (ATT/E) which allows operators to run attachments while in Economy mode.
True Tight Tail Performance
The versatile mid-size excavator can fit into areas where a conventional machine cannot. The contoured cab design and convex sliding door allow the cab to swing within the same turning radius as the counterweight.
Booms and arms are constructed with thick plates of high tensile strength steel. In addition, these structures are designed with large cross-sectional areas and large one piece castings in the boom foot, the boom tip, and the arm tip. The result is work equipment that exhibits long term durability and high resistance to bending and torsional stress.
The air conditioner, air filter, and a higher internal cab air pressure minimize the amount of external dust that enters the cab.
The mid-size excavator uses viscous mounts for the cab that incorporate a longer stroke and the addition of a spring. The cab damper mounting combined with a high rigidity deck reduces vibration at the operator's seat.
Easy Access Coolers
The radiator and oil cooler are side-by-side modules which simplifies cleaning, removing, and installing. The swing out cooler design provides easier access to the cooling cores.
The monitor provides advanced monitoring diagnostics to assist with troubleshooting and reduce costly downtime.
Rear View Monitoring System
The operator can view the rear of the machine with a color monitor screen.
A pattern change valve is conveniently located at the front of the machine, making switching from excavator controls to backhoe controls quick and easy.
