.

(2) Reliability
Improved reliability and serviceability by adoption ofMHI's AC controller which is used in our electric forklift trucks for overseas markets.
The new mast for the 1t class truck was designed
based on our current forklift mast. This assured reliability and also reduced costs by using parts incommon.
(3) Serviceability
New LCD (liquid crystal display) panel displays truck
status messages and enables the operator to customize truck settings and self-diagnose the truck
condition. These new features improved the man-machine interface.
Adoption of dual-pedal system, when operating withjoystick only the hydraulic system is activated andtraction stay stop, improved maneuverability.

This model is the first warehouse truck developed by
Mitsubishi Heavy Industries, Ltd. (MHI) and is uniqueto the North American market. This truck has high traction performance of electric counterbalanced three-wheel
forklift truck and easy on/off access of stand up rider
truck such as reach forklift truck. It meets customers'
expectation by providing precise control which has beenrealized by the industry's first AC system[1] and an electric steering system. This AC system utilizes MHI's ACcontroller which has been successfully adopted for otherelectric forklift trucks manufactured for overseas markets. To improve product quality, market surveillance
was conducted in advance and field applications understood. This process was to assure high quality. InFebruary 2007, we started production of our new model
developed in-house, whose performance and operation
are dramatically superior to current OEM vehicles, andstarted shipping them to the North American market.

Table 1 Major models and specifications

Note 1: AC motor system. Unlike current DC motors whichStandard

Itemhave brushes, AC motors have no brushes, thus easing maintenance.

1. Product Specifications
Table 1 shows the wide product lineup of the SUEC
(capacity range 1,360-1,810 kgf).

2. Characteristics
For the first time in the industry of this type of truck,an AC system has been adopted for both traction and lift
systems to improve maneuverability and maintenance.
(1) Maneuverability
Improved maneuverability by additional traction control on ramps and an anti-skid function.
Achieved good responsible operation of traction andup to 4 way hydraulics using joystick alone.
Usage of EPS [2] in the steering system improved operational feeling.
