Quarry Chain Saw Machine Nf-7.1

The chain saw machine model ”NF-7.1” is designated for the extraction of marble and stone blocks in the open sky quarries using the most recent technologies. The chain saw “NF-7.1” permits to improve the performances and to reduce to minimum the cost of the cut.
The chain saw “NF-7.1” is universal: it can execute vertical and horizontal cuts on materials with compression strength higher than 150 Mpa. The movement of the machine is made through a sprocket and rack element assembled on the rails.
The chain
The principal tool of work of the chain saw “NF-7.1” is a modular chain composed of insert-holders having, by means of mechanical fixing with a screw, inserts in tungsten carbide. The chain saw “NF-7.1” can work in manual and automatic thanks to the presence of a control device during the cutting phase.
Operating condition
Thanks further to the experience and to the tests carried out during the last 5 years, the chain saw “NF-7.1” can work in the following climatic conditions:
From -40°C to +40°C (the oil tank is provided with heater for the hydraulic oil in places where the temperature goes below 0°C)
Humidity relative to 98% at 25°C
