Areas of application

The DSWS15 is an electrically-powered wire saw which,

by means of its diamond wires, is capable of sawing

through construction materials ranging from heavily

reinforced concrete to metre-thick masonry. Equipped

with the appropriate accessories, it can be used to cut

openings of all kinds and for the technical demolition of

construction components of any shape, thus present-

ing almost limitless application possibilities. Sawing

operations are normally carried out wet, using water

cooling, but masonry can also be sawn dry.

DS WS 15 basic system units

The basic equipment consists of the following compo-

nents: drive unit, control unit, compressor, 2 single-pair

pulley stands, 1 toolbox containing tools and acces-

sories, 2 water supply nozzles.

DS-WS-SPP single-pair pulley stand

The basic equipment includes 2 single-pair pulley

stands. These are adequate for most applications but

it is also possible to use more than 2 single-pair pul-

ley stands for applications where access is difficult

(in cellars, corners, shafts).

Toolbox containing accessories and tools

Long water supply nozzle

For use at the rear of the object being cut, deep in the

saw kerf.

쐆Flexible water supply nozzle

For use at the wire entry point on the return side (slack

side) located at the front of the object being cut.
