The Comacchio MC-E line has been designed to satisfy the specific request to operate in restricted access working spaces, where particular soil configuration, bearing capacity and limited space make it impossible to use a crawler mounted drilling rig: docks, road edges, rock walls, slopes etc. The drilling attachments of the MC-E line are installed on the end of hydraulic excavator booms. Using the excavator boom movements combined with a slewing ring or with the Comacchio patented mast joint support, these machines can reach an extreme variety of mast positions and inclinations. All the mast movements and the rotary head are powered by the appropriately fitted hydraulic circuit of the excavator.
Mainly used for ground improvement works and anchor drilling, the MC-E line includes a remarkable variety of models that, depending on the excavator size, can reach up to 15 tonnes pull-up force. The drilling attachments of the MC-E line can be equipped with a wide range of rotary heads and hydraulic drifters capable of operating all rotary and/or rotary-percussive drilling systems. All set-up and drilling movements can be controlled by the operator directly from the excavator cabin, using the Comacchio radio remote control, with great advantages in terms of efficiency, productivity and safety. In recent years, the development of automated rod and casings carousels has contributed to further improvement of the safety performance of our MC-E drilling attachments.
