Integrate a Cummins Tier-4i Engine in a Haulage Truck

Montreal,Quebec

Client : Dux Machinery

Location : Montreal,Quebec

Year : 2013

DUX Machinery is a leading manufacturer of underground haulage equipment. Power mechanization of its equipment needs to change in order to meet the requirements of the environmental regulation.

The haulage truck must be adapted so that a new engine and, more importantly, new air intake and exhaust components can be installed.  

LDV was therefore mandated to finalize the selection of the engine options, validate the heat transfer equipment with regard to air intake and engine cooling and adapt the engine compartment to allow installation of a new air filter and exhaust.
