Caterpillar is pleased to introduce the 773 construction dump truck. You may be wondering how, after 40 years of effort, Caterpillar has been able to further improve its support for your business.
The 773 was designed and manufactured using the latest available technology, both in terms of software and hardware. Before going into production, this product was tested for over 30,000 hours by customers to ensure that it is ready to use, reliable, and robust.
In addition to quality, the Cat 773 will help you reduce costs by limiting fuel consumption in seven ways. We offer two customizable fuel economy modes so you can choose the level you want.
