Overview

EN 15162:2008 - Machines and plants for mining and tooling of natural stone - Safety requirements for gang saws.
This CEN (type C) standard applies to monoblade and multiblade gang saws used to cut marble, granite, other natural stones, and artificial or natural conglomerates. It addresses all significant hazards during transport, commissioning, use and maintenance - except noise, which is explicitly excluded. The standard supports compliance with relevant EU Machinery Directives (see Annexes ZA/ZB).

Key topics and technical requirements

EN 15162:2008 defines safety measures and verification requirements focused on practical machine safety. Major topics include:

• Scope & classification - Definitions for granite/hard-stone gang saws, marble/soft-stone gang saws, monoblade vs multiblade and carriage/blade positioning systems.
• List of significant hazards - Identifies foreseeable misuse and hazardous situations relevant to gang saw machines.
• Mechanical protections:
  • Carriage locking and fixation
  • Protection against end run of the blade frame (safety cam)
  • Measures for belt breakage and flywheel hazards
  • Guards around motors, flywheels and blade areas
  • Slab-holding devices and safe access arrangements

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 12100-1 and the following apply.
3.1
types of gang saws
machines for cutting of marble, granite, other types of natural stone, artificial and natural conglomerates as
well as similar materials, hereafter referred to as gang saws, are classified according to the material to be cut
and the number of blades. A further classification is based on the technology used to position the block in rela-
tion to the blades which may be done by a fixed carriage with the descent of the blades or a mobile rising car-
riage with blades at fixed height.
Following these principles, the machines in the scope are classified and described in 3.1.1 to 3.1.3
3.1.1
granite and hard stone gang saw (see Figure 1)
machine for cutting blocks of granite or hard stones into slabs.
The machine consists of 4 upright columns connected to one another which support a vertically and horizon-
tally moving blade-carrying structure. This structure moves vertically (descent movement) by a screw system
positioned in the columns and horizontally by a system composed of a flywheel connected by a rod with the
blade-carrying structure. While operating both directions together, the structure creates a swinging movement
of the blade carriage.
A mobile railed carriage moves the granite block into position under the blade carriage.
A system of pipes with nozzles above the blades provides a mixture of water, lime and abrasive steel shot
which acts as the cutting tool between the blade and the granite block and additionally ensures the cooling of
the blades
Figure 1 — Granite and hard stone gang saw
3.1.2
marble, stone, artificial and natural conglomerates gang saws
3.1.2.1
closed marble gang saws
machinery for cutting blocks of marble or soft stones into slabs.
The machine consists of 4 upright columns connected to one another which support a vertically and horizon-
tally moving blade-carrying structure. This structure moves vertically (descent movement) by a screw system
positioned in the columns and horizontally by a system composed of a flywheel connected by a rod with the
blade-carrying structure. While operating both directions together, the structure creates a rectilinear move-
ment of the blade carriage (see Figure 2). In some machines, the vertical movement is carried out by raising
the block and keeping the blade carriage at a set height (see Figure 3).
A mobile railed carriage moves the block into position under the blade carriage.
The cutting of the stone is performed by the diamond bits of the blades.
A system of pipes with nozzles above ensures the cooling of the blades

Figure 3 — Marble gang saw with closed structure and block-raising system
3.1.2.2
marble gang saws with open structure (see Figure 4)
machinery for cutting blocks of marble or soft stones into slabs.
The machine consists of an open blade frame which slides vertically inside a structure, the alternating horizon-
tal cutting movement is generated by a flywheel-connecting rod unit.
A mobile railed carriage moves the block into position under the blade carriage.
The cutting of the stone is performed by the diamond bits of the blades

Figure 4 — Marble gang saw with open structure and mobile blade carriage
3.1.3
monoblade gang saw (see Figure 5)
machinery for cutting the tops of blocks of marble or other, soft stones and to cut very thick pieces of these
stone materials.
The machine consists of a system for the vertical and horizontal movement of the blade, a tensioning system
for the blade (generally hydraulic), a block carriage and a blade-cooling system.
The cutting of the stone is performed by the diamond bits of the blade
