Chain saw

The TCM 888 is a chain saw designed to open and develop underground mines of marble and of similar stone materials. Underground mining development is becoming a more and more common practice in many marble quarry operations.
This method is often considered preferable to the open pit quarrying in terms of production optimization, efficiency, safety and environment preservation.

The machine is mounted on a crawler and it can move easily and autonomously inside the tunnel. The machine is configured as shown in the next figures to reduce the overall dimensions and to move over slopes up to 25%.

All the movements of the crawler and the positioning devices of the machine are made possible by an on-board “power pack” unit equipped with a diesel engine. During the cutting operation, the machine should be simply connected to the 400V/50Hz power line through cable and on-board plug. All the functions are controlled by means of a remote control board without cable and of a touch-screen panel.
