Terex Trucks has announced that a range
of articulated haulers meeting the requirements of new U.S. Environmental Protection Agency (EPA) Tier 4 Final emissions
regulations will be available soon in North
America. The 30-metric-ton (mt) capacity
Terex TA300 hauler will be available initially, with the 40-mt TA400 entering production during August. Powered by Scania
engines, the new articulated haulers not
only feature low emissions, but also offer
operating convenience as their Tier 4 Final
system does not require a diesel particulate filter (DPF), reducing maintenance
and fuel consumption. Terex Trucks’ Tier 4
Final technology also features latest generation Selective Catalytic Reduction
(SCR) combined with Exhaust Gas
Regeneration (EGR) technology and a
Variable Geometry Turbo (VGT). The combination of EGR and SCR, plus a diesel
oxidization catalyst (DOC), increases the
efficiency of the SCR process.
A new feature resulting from the Tier 4
Final technical package is the introduction
of a CAN-controlled engine exhaust brake.
This, according to the company, provides
improved reaction and performance
of exhaust brake retardation and higher
efficiency of Tier 4 Final after-treatment
requirements, resulting in greater operator
control and braking in downhill applications, further improving safety.
