Overview

This new diesel 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 FH series achieves reduced costs of operation and reduced maintenance costs. The FH 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.

Features

Heavy Duty Sealed Wet Multi Disc Brakes

With many years of field-proven performance in Komatsu construction equipment, the FH’s sealed wet multi-disc brake system provides 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 downtime.

Electronically Controlled HST

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.

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.

KOMTRAX

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.

Low Exhaust Emissions Engine

Komatsu’s turbo-charged 4-cycle diesel engine is Interim Tier 4 and EU Stage A emissions certified, without sacrificing power or productivity. 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.

Controllability and Operation

The FH series requires less inching pedal use because the HST forklift can adjust speed through the use of the accelerator pedal. Also with 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 for 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.

Reduced Roll Back

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 also facilitates easier ramp-start.
