Onyx Tunnel Chain Saw Machines

All Fantini chain saw machines can be equipped with a radio remote control.
The radio remote system allows the operator to move around the machine: no cable is needed to be connected to the remote control, so the operator can stay far from the chain saw in a safe position more suitable to check the movements of the chain saw.
Each radio remote control has a unique transmission program set by the producer and unchangeable, so that each transmitter can interact only with its receiver and cannot interfere with any other radio remote controls.
The frequency of work used by the radio remote control can be easily set and changed by the operator between 128 different frequencies. The operator can work even near other radio controlled machines.
Supported models:
- All chain saw machines
- All chain saw machines for underground quarries

Electric diamond belt sawing machine, designed to make tunnel cuts, vertical and horizontal. The JET BELT 940 is composed of two columns with two telescopic extensions for the machine fixing, connected with an horizontal beam of 462 cm that bears the electric cutting unit. This is composed of the main motor and the cutting arm with the diamond belt installed. The column bases are motorized for an easy positioning of the whole structure. The cutting tool consists of aspecial plastic belt with sintered diamond segments. Only water is used during the cutting phase, both for lubrication and cooling, so that no dust is produced during the cutting phase. Another advantage of diamond belt cutting system respect to the traditional one, is that no grease or oil are used, so that the cut is very clean and free from pollution load.

Underground chain saw can extract high grade marble directly without striping mmaintain skins or soils.
Less requirement on lamd expropriation, less wastes and rubbles, less cost on deslag and revegetation, less environment damage.
Better block shape and higher yield rate
High extracting efficiency without being affected by wether. Even higher efficiency of future expending extracting to sides or downward
Low overall cost and low risks. High long term benefits
