This chain saw is composed of a cutting system mounted on a wheel loader. The machine is self-contained, quickly moving and positioning in front of the block or to the bench to be cut. There is no need to prepare an area reserved to the squaring of the blocks in the quarry, as the machine can easily and quickly reach the blocks to be cut. It can work in dry conditions, without using any water to cool the cutting tools. The operator can use a wireless control for all the functions of the machine, which can be used either inside the heated/air-conditioned control cabin or outside the machine.
