Many manufacturers of construction machinery pay great attention not only to the technical characteristics of their products, but also to the environmental requirements of the machinery. Thus the company Case Construction Equipment introduced new models of wheel loaders 621F and 721F that meet Tier 4 Final emissions standards. Due to selective catalytic reduction system engineers managed to improve fuel efficiency (up to 20 percent greater than previous solutions). Developed improvements provide excellent throttle response and simplify maintenance without sacrificing power. Also the selective catalytic reduction system helps to reduce peak loads in the engine system and lowers the exhaust gas temperature during long operations.
Equipped with one of the best-in-class horsepower with a 6.7-liter engine wheel loaders 621F and 721F have a capacity of 121 and 133 kW respectively. The operator can adjust the engine downtime, which also leads to a reduction in fuel consumption.
Competition in the production of construction machinery is enormous, no doubt the focus of Case Construction Equipment on economical efficiency and green technology will help to attract new customers.
