Cat Lift Trucks’ DP40N1-DP55N1 Series of diesel pneumatic tire lift trucks are designed to meet the U. S. Environmental Protection Agency’s (EPA) final Tier 4 emissions standards. The lift trucks have 8,000-12,000 lb. capacity and feature a new diesel engine that provides a 21.6% increase in fuel efficiency in addition to increased performance, reduced emissions levels, and a lower total cost of ownership, according to the company.

The new diesel lift trucks feature increased energy efficiency and performance. The diesel particulate filter (DPF) on the new DP40N1-DP55N1 will automatically regenerate. This takes place during normal operation, so there is no work cycle interruption, even at low engine speeds. In addition, it results in 90% reduction in particulate matter and the nearly 50% reduction of NOx. The unit’s Perkins 854F engine operates without requiring any ash service and features low-noise levels.

This 8,000-12,000 lb. capacity diesel lift truck series is the first Cat lift truck product to feature a new Tier 4 Final engine, with several additional products to be offered throughout 2013 and 2014.
