The redesign was a result of the enforcement of the combustion engine exhaust gas legislation in Europe and the US that came into force in January 2011 and introduced new Stage 3B/Tier 4i engines.
The vehicle comes with either a Stage 3A/Tier 3 or Stage 3B/Tier 4i engine, depending on the legislation in force.
In Australia, the legislation regarding emissions for off-road earthmoving equipment is State-based and relies on what equipment is available overseas. With this in mind, the QJ341 with the older Stage3A/Tier 3 engine or the new Stage 3B/Tier 4i engine, may be used in Australia.
The QJ341 retains the features of the QJ340 as well as incorporating new features such as a load control system for the feeder drive, a level sensor fitted to the jaw and a speed wheel fitted to the main conveyor.
