The GRENDiA from MHI is developed to (1) satisfy
ever stricter customer demands for optimal environmental protection, (2) reduce the causes of hazardous
accidents, and (3) reduce operation costs. The design
improvements are made possible through a distributed
arrangement of controllers and electronic control basedon the on-vehicle LAN connection. The GRENDiA debuted in Japan and Asia in June 2003, then launched in
the United States and Europe. The GRENDiA of today
is still evolving, taking on new functions to meet theneeds of customers.

System) as standard. The vehicle can also be equippedwith a speed limiter for customers who want to improve safety in their factories and workplaces. The
speed limiter improves workplace safety and reduces
the incidence of accidents.
(3) Several mechanisms are built into the GRENDiA toimprove operation costs. The vehicle can work in"limp home" mode to keep the engine speed at or below a certain value in order to prevent engine failuresdue to overheating. This protection is only available
through electronic control. The vehicle also incorpor a t e s a T M S ( Tr a c k M a n a g e m e n t S y s t e m ) t oquantitatively grasp the operating time, travelingtime, lifting time, etc. of a forklift truck. This function is especially useful, as it allows plant managers
to plan vehicle assignments and other operations
based the amounts and types of work. If and when afailure occurs, various error codes will display on themeter panel to minimize the machine downtime. Thevehicle also has interfaces to allow service personnel
to connect service tools to the vehicle controller, enabling accurate vehicle diagnosis.

1. Characteristics(1) The electronically controlled engine of the GRENDiA
attains the best environmental performance in its
class. The GRENDiA runs in soft mode at limited
engine power to meet the demands of customers who
require improved fuel efficiency or reduced noise atnight (because they run the machines night and day).
The fuel efficiency of diesel-engine vehicles is improved by 12 to 13%. The vehicle noise of diesels isreduced by 3 dB(A) (compared with standard vehicles).
(2) The GRENDiA incorporates Mitsubishi's own mast/
traveling interlock function (IPS: Integrated Presence
