Forklift truck industries nowadays have heightened
requirements for easy operation, comfort, and convenience, even for their larger-class vehicles. Mitsubishi
Heavy Industries, Ltd. (MHI) has responded by developing a large-class forklift truck (load capacity of 8 to 16tons) with drastically improved features to meet theserequirements. The new vehicle has been on sale sinceFebruary 2007.

1. Specifications
Table 1 shows the specifications of the new forklift
truck. Fig. 1 shows the external appearance.

2. Characteristics(1) One of the first forklift trucks to meet the new domestic regulations on exhaust emissions
The PM (black smoke) and NOx (nitrogen oxide)
contained in the exhaust gas are reduced by 40 to 50%

compared with our conventional models. The reduction is accomplished by two mechanisms: acommon-rail-type fuel injection system to inject highpressure fuel for increased combustion efficiency andaccurate control by computer. The vehicle is driven
by a diesel engine that meets what have been described as the world's toughest regulations on specificvehicle exhaust emissions (Japan's Ministry of the Environment, Ministry of Economy, Trade and Industry,and Ministry of Land, Infrastructure and Transport).
(2) Low vibration and low noise
Low vibration and low noise are realized by adopting a full-floating cabin completely independent of theengine room, in addition to the conventional powerline full-floating technology.
(3) Operation as easy as driving a passenger car
Fatigue is reduced by a steering wheel, levers, andpedals as light as those of small trucks. The hydraulic system includes a proportional directional valve
as standard equipment, allowing the operator to select between two types of control, lever control andfinger control (option).
(4) Safety in traveling and cargo handling
The vehicle is equipped with Mitsubishi's interlock system, a mechanism to lock the mast control
and vehicle movement when the operator leaves hisor her seat.
(5) Easy maintenance
Daily checks can be performed by opening the covers with one-touch operation. A simple tilt of the cabingives engineers full access to the engine, transmission, and hydraulic system for heavy maintenance.
The engine oil lubrication interval is extended to 500
hours, as in the new small series.
(6) High reliability and durability
A high-rigidity frame with firm connection between
the side frames (tank portion) and integrated center
frame ensures excellent durability and reliability. In
addition, a wet disk brake is available as an option
for the 8- to 15-ton models (standard equipment forthe 16-ton model), making it easier to carry out longhour work operations.
