Caterpillar's Tier 4 leader

摘要

The new G Series 775 off-highway truck is the first Caterpillar machine to go into production with a Tier 4 Final emissions solution. Many of the other new machines, such as the wholly redesigned H Series 627 wheel tractor-scraper, will showcase a Tier 4 Interim version. The emissions reduction technologies have been integrated into the machine design, allowing Cat Tier 4-ready products to perform at peak production while reducing emissions by approximately 90%, according to the company.
