"Achieving an exceptionally high standard for the 5 major qualities required of construction machinery",
that is the solution provided by the SPACE5 engine that will meet the demands of the next generation. |

| Common Rail Fuel Injection System |
Cooled EGR System |
4-valve DOHC Turbo Engine with Inter-Cooler |
The super-high-pressure common rail fuel
injection system realizes super-high-pressure, high-precision multiple-injections. Timing and
volume of fuel injection is controlled, which
improves consumption efficiency, and
PM (particulate matter) is greatly reduced.
|
Exhaust gas is re-circulated and combustion
temperature lowered by the EGR (Exhaust Gas
Recirculation) engine. In addition, a water-cooled EGR system has been employed, which further
efficiently reduces NOx (nitrogen oxide).
|
Air intake efficiency is improved by the intercooler.
It cools air taken in, which has been heated by the compression of the turbo charger. In addition to a great reduction of NOx and PM, high output and
improved fuel consumption have been realized.

Rich horse power |
|
 |
| An engine rated at 132kw with a turbo charger provides enough power for any types of operations. |
|
Tier 3 emission engine. |
|
|
| The new engine complies with the Emission Regulation U.S.EPA Tier III,and EU stage IIIA. The advanced low noise design complies with upcoming EU noice regulation 2000/14/EC,STAGE II.

|
In-shoe motor |
|
|
| The running motor employs a direct HST drive installed inside left and right side sprockets. It is a structure that does not require the use of a drive chain, so extra labor created by chain adjustments is eliminated. This means that construction can be carried out in the assurance that running stoppages caused by the chain breaking will not occur. |

|
Utilization of a link-shoe that employs durable rubber pads |
|
|
| The link-shoe utilizes rubber pads, which can run on road surfaces that have already been set without marking them. In addition, the link employs a high durability strut structure.

|
Harnessing superior movement stability |
|
|
| By using the latest feedback control technology, deviations from the set course are kept to just 0.2%, which means operators are freed from the troublesome task of making steering corrections. During construction, the status and weight of loads on left and right sides is continually monitored, so that even for jobs requiring large quantities of materials to be carried on one side, the course and speed settings are automatically maintained by the control system.

|
Employing the latest travel control system |
|
|
 |
|
The engine, hydraulic pumps, and running motor are centrally controlled with fine precision by a computer. In addition, settings are stored in the computer's memory, so construction can be carried out simply by turning the running switch to "on" or "off". The HA60C's controller contains the following special features
1.Fluctuations of speed due to changes in the wei-
ght of load do not occur, so paving smoothness
is improved.
2.Deviations from the set course caused by chan-
ges in the weight of load are very small, so une-
ven
ness in forward movement is reduced to an
absolute minimum.
3.Paving speed can be set to a minimum of 1.5m/
min. It is adaptable to all kinds of construction.
4.At the start of construction works, a control fun-
ction is used to achieve a soft-start.
5.Paving speeds can be set and altered even when
at a standing stop.
