The Mitsubishi GRENDiA forklift truck was first marketed in June 2003. It includes many
new technologies related to safety and the environment. These include features such improved
operator comfort (e.g., less vibration, reduced noise, and improved functionality insteering handle, control lever, pedal, etc.), early compliance with European and North American
exhaust gas emission standards, and an interlock system that prevents loading, unloading,or movement in the absence of a seated operator. In September 2008, the vehicle was marketedin Japan, already compliant with the 2007 domestic exhaust gas emission regulations ahead of its
competitors. This paper describes the new GRENDiA model.

|1. Major modifications
1.1

Compliance with 2007 exhaust gas emission regulations(1) Diesel engine model
We have improved performance to achieve environmental friendliness withoutcompromising the basic performance of the highly acclaimed Mitsubishi diesel engine.
note
The engine meets the 2007 exhaust gas regulations .
Figure 1 is an external view of the Mitsubishi diesel engine installed on the GRENDiA,
which has a rated capacity of 2–3.5 tons.
Note: Emission Standard for Specific Special Vehicles (including off-road vehicles).

(2) Gasoline engine model
We have achieved excellent environmental performance in meeting the 2007 emission
standard while maintaining high power and reliability through a further evolution of
the high-performance gasoline engine, which was already an industry leader in the use of anelectronically controlled fuel injection system and a three-way catalytic converter.

1.2

Rear axle reinforcement (improved endurance)

We reinforced specific parts of the rear axle (Figure 2) which was a key element in thisinitiative requiring utmost endurance and improved the vehicle’s endurance, to extend the required
maintenance interval for which market needs are increasing.

1.3

Integrated digital monitor

We have already expanded the use of electronic control systems to the engine itself to help
meet the more stringent exhaust gas emission regulations. We have added an LCD digitalmonitor so the operator can monitor the vehicle’s status and indentify faults in case of malfunction.
Figure 3 shows the monitor on the new GRENDiA compared to that of the old model(shown in Figure 4).

The digital monitor has the following major functions:(1) digital speedometer(2) clock(3) three types of hour meters (engine, key switch, and seat switch)(4) LED warning lights for error code indications and error code history (maximum of 32 events)(5) load weight display (available as an option only for the two-stage panorama mast)(6) operator recognition (available as an option only for power shift transmission)(7) service reminder (alarm for recommended maintenance, available as an option)(8) speed and load alarm (available as an option)(9) fuel gauge and water thermometer|2.
