FH70/80

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.

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.

In the HST system, the diesel powered engine drives the pump and oil supplied from the pump then rotates the motor that drives the forklift. The power losses over the entire engine speed range are minimal. Since the HST system does not have a clutch, there is no possibility of heat loss or slippage. This means power transmission losses are minimized to reduce fuel consumption. The engine is connected to the drive system hydraulically to transmit power to the drive system. This makes it possible for the FH series to make directional shifts smoothly without the need to release the accelerator pedal.

The FH70/80-2 utilizes a field proven sealed wet multi-disc brake system to provide excellent braking performance in all operating conditions. The sealed system provides protection from dust, dirt and debris, thus providing higher reliability, fade and water resistance. Unlike a drum brake system, there is no need to replace the brake shoes resulting in lower maintenance costs and reduced downtime.

KOMTRAX, a standard feature on the FH series, is Komatsu’s remote equipment and fleet monitoring system. Leading-edge wireless technology and a secure, user-friendly web-based application provide critical information…anytime, anywhere. KOMTRAX tells you where your machines are, what they are doing, and how they are doing it providing total fleet management capabilities for improved fleet utilization, reduced downtime and lower owning and operating costs.

Komatsu’s turbo-charged 4-cylinder diesel engine is Tier 4 Final emission certified, without sacrificing power or productivity. Komatsu’s Tier 4 Final solution uses a diesel oxidation catalyst, variable flow turbocharger, EGR and closed crankcase ventilation which eliminates the need for regeneration. The FH70/80-2 does not need a diesel particulate filter resulting in reduced maintenance costs and reduced downtime.

With HST drive, the oil flow to the hydraulic motor is stopped when the accelerator pedal is released, so even if the forklift is stopped on a ramp and the operator releases the brake pedal, downhill creep is reduced. This feature also facilitates easier ramp-start.
