Komatsu’s FH70/80-2 Series hydrostatic drive family achieves its durability and low costs of ownership from its rugged designs and field proven components. With Komatsu’s hydrostatic drive system, standard wet disc brakes, and Closed-center Load Sensing hydraulic system (CLSS), the FH70/80-2 series achieves reduced costs of operation and reduced maintenance costs. The FH70/80-2 series lowers your cost of operation in a variety of demanding, high-cycle operations. Also equipped with KOMTRAX — Komatsu’s exclusive information data management system.
CLSS WITH VARIABLE DISPLACEMENT PUMP
Komatsu’s CLSS hydraulic system has been utilized in our hydraulic excavators for many years. The load sensing capability automatically senses loading and the variable displacement pump then supplies only the amount of hydraulic fluid needed to do the job. This provides for much greater efficiency than conventional fixed displacement gear pumps, making good use of engine power to reduce overall fuel consumption.
CONTROLLABILITY AND OPERATION
The FH70/80-2 series has no inching pedal because the HST forklift can adjust speed through the use of the accelerator pedal. Also with the excellent controllability of the HST, the operator has better control when maneuvering in tight quarters, lifting, or load handling. Travel speeds can be set in four stages and activated with the turtle switch. To eliminate inadvertent start-ups, the FH engine can only start when the shift lever is set to neutral, brake pedal depressed and the operator is in the seat.
