About · Caterpillar D8T

Overview

The Caterpillar D8T is a large crawler bulldozer in the 35–40-tonne class, in production since 2005. It delivers 354 hp from a Cat C15 ACERT engine and pushes an 8.7 m³ semi-U blade. The current generation offers Cat's GRADE system as an option for automated 3D grade control. A Stable Blade system actively compensates for ground irregularities. The cab is ROPS/FOPS certified.

Typical applications

Where this machine is used

German quarry operators use the D8T for primary limestone and hard rock stripping, where its ripping force enables productive work in material that stalls smaller machines. Road contractors across Benelux and Germany use it for mass earthmoving on motorway interchange and rail embankment projects. It is also used for large port and flood-defence earthworks where high material throughput is required.

Used-market inspection

What to check before buying

A full D8T undercarriage rebuild costs €40,000–€65,000 depending on specification and labour. Request an independent undercarriage measurement report before purchase. The C15 engine is durable, but oil consumption above 0.4 L per 100 hours indicates liner or ring wear. Evaluate the power-shift transmission on high-hour machines via an oil pressure test and VIMS fault history. Inspect main frame and push-arm welds carefully on machines from quarry environments.

Current market

Price position

The D8T competes with the Komatsu D155. Cat's European dealer network supports parts availability and residual values. The German and Swiss markets show the strongest demand for large dozers, driven by quarry and road infrastructure work. Prices for 2015–2022 machines have held firm, with GPS-equipped examples attracting premiums from contractors seeking to reduce grading costs.
