À propos · Komatsu D85EXAperçu
The Komatsu D85EX is a large crawler bulldozer in the 25–30-tonne class, in production since 2000. The EX designation indicates the standard-track configuration suited to firm ground and quarry work. The Komatsu SAA6D125E-5 engine produces 264 hp. The machine pushes a 6.0 m³ semi-U blade with a drawbar pull exceeding 35,000 kg. The D85EX-18 generation features Tier 4 Final compliance, KOMTRAX remote monitoring, and an auto-blade-assist function that adjusts pitch and angle during a push cycle.
Applications typiquesLieu d'utilisation de cette machine
European quarries use the D85EX for primary ripping and dozing of limestone and sandstone overburden. Up to 4-shank ripper configurations are available for breaking compacted rock before loading. German contractors also deploy it for large-scale earthmoving on motorway and rail corridor projects. Additional applications include large-area land reclamation and coastal defence embankment work.
Inspection du marché de l'occasionCe qu'il faut vérifier avant d'acheter
Inspect the ripper frame and tine shanks for cracks near weld zones, which are common on machines used in hard rock. The hydraulic main pump and control valve assembly cost €15,000+ to replace. Request hydraulic pressure test results. Check track bushing wear at the turn point: rotation from the wear track means replacement is due. Inspect the final drive oil for metal particles at each purchase inspection.
Marché actuelPosition tarifaire
The D85EX competes with the discontinued Caterpillar D7R and the Liebherr PR744 in the 25–32-tonne range. Demand in Germany's quarrying and construction sector is consistent. The model's long production run provides a healthy supply of used machines at various price points. Prices faced moderate pressure in 2025–2026 as high-hour machines from quarry operators cycled out of service.
