About · Komatsu D155Overview
The Komatsu D155 is a large crawler bulldozer with an operating weight of 40,506 kg and an engine output of 354 hp. It has been in continuous production since 1979, establishing a long service record across heavy earthmoving applications. The machine is equipped with a blade capacity of 9.4 m3, placing it firmly in the upper tier of the crawler dozer class alongside equivalent machines from Caterpillar and Dressta.
Typical applicationsWhere this machine is used
Large crawler bulldozers in the D155 class are suited to heavy earthmoving, bulk material pushing, land clearing, and site preparation on major civil and mining projects. Their blade capacity and drawbar pull make them effective for maintaining haul roads, constructing embankments, and reclamation work. Operations requiring sustained high-volume material displacement over extended shifts are the primary domain for machines of this power and weight category.
Used-market inspectionWhat to check before buying
Inspection of a large crawler bulldozer should prioritise the undercarriage, as track components, rollers, idlers, and sprockets represent a significant portion of ownership cost in this class. The final drives and transmission should be checked for leaks, noise, and smooth engagement under load. Blade, push arms, and tilt cylinders warrant close examination for cracks, wear, and cylinder seal condition. Engine hours should be corroborated against service records, and oil analysis history, if available, provides useful insight into internal component condition. A pre-purchase inspection by an independent qualified technician is advisable before committing to a machine of this size and value.
Current marketPrice position
In the European market, the Komatsu D155 carries an average asking price of EUR 263,792, with a typical price range spanning EUR 254,977 to EUR 272,137. Direct competitors in this weight and power class include the Caterpillar D8 and the Dressta TD-25, both of which occupy similar positions in the large crawler dozer segment. Buyers should assess how individual machine condition, configuration, and blade type influence positioning within that price band.
