Caterpillar D8

From Wikipedia, the free encyclopedia

The Caterpillar D8 is a large track-type tractor designed and manufactured by Caterpillar Inc.

Though it comes in many configurations it is usually sold as a bulldozer equipped with a detachable large blade and a rear ripper attachment.

[edit] Dozer blades

The dozer blade on front of the tractor usually comes in 3 varieties:

  1. A Straight Blade ("S-Blade") which is short and has no lateral curve, no side wings, and can be used for fine grading.
  2. A Universal Blade ("U-Blade") which is tall and very curved, and has large side wings to carry more material.
  3. A "S-U" combination blade which is shorter, has less curvature, and smaller side wings.

Various other blade types are used including landfill U-Blades, woodchip U-blades, and two-way blades for work inside the holds of ships.
