Resources
Features and benefits
Improved machine efficiency
The new D155AXi-8 has achieved both high levels of productivity and fuel economy with the SIGMADOZER blade and automatic transmission with lockup torque converter and new Tier 4 Final engine. From these 3 key features the bulldozer significantly improves fuel efficiency compared with our conventional models
Unrivaled blade visibility
The D155AXi-8 has a strong integrated ROPS cab with large glass windows for outstanding visibility. High rigidity and superb sealing performance greatly reduce noise and vibration for the operator and helps prevent dust from entering the cab. The standard air-suspension seat positions the operator comfortably.
Hydrostatic steering system
The engine power is transmitted to both tracks without power interruption on the inside track for smooth, powerful turns. Counter rotation while in neutral is available for minimum turning radius providing excellent maneuverability.
Tier 4 engine KDPF regeneration
As the technology of diesel engines has progressed from Tier 3 to Tier 4 Final, design aspects of the engines have been fine-tuned to comply with regulations to cover regulated diesel engine exhaust pollutants.
The result is that these new diesel engines are cleaner than ever before, and in many cases more fuel efficient too. Along with this comes the need to properly manage and maintain these new generation of machines to make sure that operating costs are minimised.
