Machines and plants for mining and tooling of natural stone - Safety - Requirements for chain- and belt-slotting machines

Asnjë informacion i shtuar.

This standard applies to chain- or belt-slotting machines to be used in open or underground quarries. Chain- or belt-slotting machines are used for cutting marble, granite and other stones loose or at the face. They can be stationary or can be moved on rails during work. This standard deals with slotting machines with electric main motor and equipped with one main sawing head. This European Standard covers only machines for plain cutting (with one axis) and does not cover the difficul-ties arising from the geomorphology of the stone to be cut. This standard does not deal with noise as a significant hazard. This standard deals with all significant hazards, hazardous situations and events relevant to chain- and belt-slotting machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard deals with the hazards during transport, commissioning, use and maintenance. This European Standard does not deal with: operation under extreme ambient conditions (outside the limits defined in EN 60204-1); operation in a potentially explosive atmosphere. This document is not applicable to machines which are manufactured before the date of its publication as EN.
