FH135-1 Komatsu diesel forklift specs & dimensions (2019 - 2026)

Workability & Durability

Build upon Komatsu unique hydraulic technologies Electronically-controlled HST provides exceptional operability High-quality and reliable Komatsu components Heavy-duty sealed wet disc brakes

Cooled Exhaust Gas Recirculation (EGR)

Cooled EGR system recirculates a portion of exhaust gas into the air intake and lowers combustion temperature, thereby reducing NOx emissions. The system achieves a dynamic reduction of NOx, while reducing fuel consumption.

Komatsu Closed Crankcase Ventilation (KCCV)

Crankcase emissions (Blowby gas) are passed through a KCCV filter, traps oil mist which is returned back to the crankcase for combustion. PM emission is reduced and results in cleaner exhaust gas.

Superior Fuel Economy

The FH series incorporates the combination of the high efficiency Komatsu engine, “Electronically-controlled HST” and “Variable displacement pump with CLSS” technologies, that can provide powerful performance with at most 30% reduction on fuel consumption. Significant fuel economy can be achieved especially in high cycle operations where fast-paced loading, unloading, and directional changes are prevalent.

Outstanding Environment-friendliness

The reduced fuel consumption enables reducing CO2 emissions. In case of high load work, in annual 28.9 ton CO2 emission can be reduced.

Automatically Controlled Engine Output

The load weight is detected by sensor, and engine output is automatically controlled when the load is light. This feature contributes to reducing fuel consumption.

Build Upon Komatsu Unique Hydraulic Technologies

The FH Series was designed to utilize highly reliable, field-proven Komatsu’s drive and control components that have been used for many years in Komatsu construction equipment. The travel system is “Electronically-controlled HST”, Komatsu’s unique hydraulic drive system that has been employed for Komatsu wheel loaders and bulldozers. The lift hydraulic system uses “Variable displacement pump with CLSS”, a highly efficient hydraulic system employed in Komatsu hydraulic excavators. The FH Series models are powered by a Komatsu designed and manufactured diesel engine that features advanced engine technologies. All these are combined to achieve superior fuel economy, reduced environmental load and outstanding controllability.

Electronically-controlled HST Provides Exceptional Operability

The HST drive system is continuously variable speed transmission and provides smooth acceleration and stepless ratio changes, thus there are less shock and worries for load shifting.

Controlled Rolling Back on a Ramp

The HST drive system has a self-braking feature which hydraulic flow of fluid is stopped by releasing the accelerator pedal. This feature prevents uncontrolled rolling back and holds the truck on a ramp while the operator releases the brake pedal for a ramp-start.

High-quality and Reliable Komatsu Components

All of the FH series main components, such as engine, hydraulic pumps, hydraulic motor, axles and controllers are designed, developed and manufactured by Komatsu, ensuring the quality and reliability that comes from exacting Komatsu engineering standards.

Hydraulic Connections with O-ring Seals

Hydraulic connectors in the truck are flat face-to-face O-ring seal type, which provides secure seal to prevent oil leakage. They are also widely used in Komatsu construction machinery and their reliability is field proven.

Heavy-duty Sealed Wet Multiple-disc Brakes

The FH series forklift trucks are equipped with sealed wet multiple-disc brakes which its performance is field-proven by Komatsu construction equipment. The sealed wet multiple-disc brakes provide protection from dust, dirt and debris, providing superior durability, fade and water resistance, promoting constant and stable brake performance in high cycle operations.

Fully Hydrostatic Power Steering Provides Excellent Maneuverability

The FH series features a small-diameter steering wheel with an ergonomically optimized design. The fully hydrostatic power steering mechanism provides excellent maneuverability in the switchback operations. The steering knob synchronizer function is also included as a standard feature.

Prevention of the lift operation when turning off the key

When the key switch is off, lift function is locked and assures that the fork and mast will not operate if the control lever is touched by accident, thus supports safe operation.

Auto engine shut down function

Auto engine shut down function is equipped as standard. If the operator applies the parking brake, sets the directional lever in the neutral position and leaves the forklift truck but without stopping the engine, the engine is automatically shut down after a preset time. This feature contributes to prevent unnecessary fuel consumption caused by needless idling. (Engine shutdown time can be set from 1 minute to 5 minutes)

Smooth directional changes without releasing accelerator pedal

The engine is not mechanically connected to the drive system, but rather connected hydraulically to transmit tractive force, making it possible for the FH series forklift trucks to make directional changes smoothly without the need to releasing the accelerator pedal. This greatly enhances ease of operation.

Precise travel control at very low speed

Approaching and stopping at the cargo and shelves needs precise travel control at a very slow speed. The FH series is equipped with sophisticated controller that realizes smooth slow speed travel by simply operating the accelerator pedal, resulting in less fatigue.

No creeping

The FH series does not creep like conventional torque converter trucks even if the operator releases the brake pedal while the directional lever is in F or R position. This feature contributes to reduced risks in confined areas and when approaching to pick up a load.

Seat belt interlock function (Optional)

The seat belt interlock function allows traveling or lifting only when the seat belt is fastened. If the seat belt is unfastened during operation, traveling and lifting power is cut off.

Operator Presence Sensing system

The traveling/lifting Operator Presence Sensing system allows traveling or lifting only when the operator is seated. It provides a double safety measure by requiring the operator to sit securely and return the directional lever to the neutral position before traveling.

Neutral start function

The FH series engine is only permitted to start when the operator is in the seat, the directional lever is in the neutral position and the brake pedal is kept depressed. This function prevents sudden starting of the forklift truck, thus supports safe operation.

Parking brake warning indicator

When the operator leaves from the truck without setting the parking brake, an indicator lamp flashes and a buzzer sounds intermittently. The buzzer also sounds if the operator presses the accelerator pedal while the parking brake is engaged, thereby protecting against excessive brake wear.

Headlight warning indicator

When the key switch is off without turning off the headlight switch, an indicator lamp turns on. This helps prevent a flat battery caused by forgetting to turn off the headlight switch.

Maintenance tracking

When the machine approaches or exceeds the oil and filter replacement interval, the monitor panel will display lights to inform the operator.

Rear view mirror

A large size mirror is mounted on the rear of overhead guard, eliminates blind spots when traveling in reverse.

Rear view camera and monitoring system (Optional)

Rear view camera is mounted on the rear of the truck, provides clear rear view through 7 inches large liquid-crystal display. (Available for truck with steel cab)

Enhanced Accessories Provides Additional Value

A simple load scale that allows the cargo weight to be measured in 10 kg steps is standard. If the load exceeds the set weight, the buzzer sounds to inform the operator. This diminishes the risk of exceeding the weight limit.

Comfortable Cockpit Reduces Operator's Fatigue

Deluxe suspension seat with armrests is standard equipped. Fore-aft, seat height, lumber support and weight adjustments are provided, enables the operator to sit in a relaxed state. Thus, provides comfortable work space and reduces operator’s fatigue.

Seat side control levers with armrest

Control levers are located at operator’s seat side to provide superb work equipment controllability. Armrest is fitted as standard to minimize operator’s fatigue.
