Excavation Offering

When performing excavation work in tunnel construction, many contractors prefer using versions of standard machines converted to suit the confines of tunneling applications. Some contractors opt to buy machines adapted for the task by manufacturers, while some opt to adapt their own units. Ventilation and engine emissions are areas of concern in regard to these machines. Applications discussed include machine features, as well as drilling and blasting. Companies profiled include Caterpillar, Liebherr, and Sandvik Mining and Construction.
