Manufacturer: Caterpillar ➔
Model: D7E ➔

Caterpillar D7E is a crawler dozer designed for earthmoving, grading, and site preparation in construction, mining, and forestry applications. The D7E uses Caterpillar's electric drive system, which replaces a traditional mechanical transmission with electric propulsion components to improve efficiency and control. It is built on a tracked undercarriage for traction in soft, uneven, or steep terrain. Typical uses include bulk material pushing, land clearing, road building, and finish grading. The machine is part of Caterpillar's medium dozer lineup and is commonly configured with a straight blade or semi-universal blade, depending on application requirements.
