The utmost importance of safety rules
The bulldozer is an imposing machine and it is important to follow a precise protocole to ensure safety rules are complied with. Work on slope, in humid or obstructed areas, the use of a dozer can be difficult. Concentration is important when using the ripper because the driver needs to watch the back and the front of the machine, or when using a wheel dozer since it has a lower adhesion on the ground than tracks. Simple actions such as the safety belt use, wearing a hearing protection (the decibels are important inside the cab), or wearing sunglasses when working a clear terrain, are essential.




The main dozer manufacturers
The most emblematic manufacturer of dozers is probably Caterpillar. Manuafacturer of oversized dozers such as the famous Caterpillar D11 and supplier for the American army, Caterpillar now has an undoubted reputation.
Other makes have stood out with innovative models and now occupy an important part of the market, such as Liebherr that manufactures machines that are more and more efficient, such as the PR 766 and Komatsu, Japanese group that put on the market the biggest dozer in the world, the D 575 weighing more than 152 tons for 1 150 hp.
New Holland, Shantui, Fiat, or Case are other bulldozer and equipment manufacturers that proved their reliability.

Evolution and technical innovation of bulldozers
Through the years, bulldozers have evolved and benefited from technologic progress. The safety norms have been upgraded and increased as well as their performances. Like many vehicles, they now use little energy, reduce their environmental impact while keeping the same power.
Bulldozers are complex machines and lots of their characteristics are bound by innovation. Thus, deformable tracks offer an outstanding grip and the hydraulic cylinder system are more robust than ever. The new technologies also brings important progress to the automation of bulldozers, equipped with slope sensors, level difference and orientation calculator, the work can be done to the millimeter, faster and with an impressive efficiency.
We still are a long way from robotisation but who knows ? Maybe tomorrow we will see dozers and other machines working autonomously ? It is too soon to say it, however it is certain that improvements and innovations are still to come.
