The LGR5 INVERTER is the cutting machine with diamond wire intended for use in marble, granite and ornamental stone quarries, to perform both cuts at the quarry front and for squaring the blocks. The machine has a flywheel motor unit that rotates 360 ° and moves horizontally and vertically; this allows two parallel cuts of mt. 1.45 with a single positioning. The movements are hydraulic and are operated from the remote-control panel. The machine is moved by means of a gearmotor, toothed driving wheels and slotted tracks, which thus guarantee excellent stability of the machine during all cutting operations.

INVERTER

The machine is equipped with an inverter to vary the speed of the diamond wire from 0 to 40 m / sec and an inverter for pulling to vary the tension load on the wire. The use of the inverter allows to adjust the speed of the diamond wire during all the cutting phases, and to have gradual starts and stops. Therefor ideal for hard and abrasive materials and for cuts of considerable size and difficulty. The machine is equipped with a forced ventilation system with air filtering to reduce the operating temperatures of the inverter.

SAFETY PROTECTIONS

Lochtmans's diamond wire machines are equipped with accident prevention means to avoid any risks taken by those who work near the machines, as the breaking of a diamond wire can generate the projection of circuit elements (pearls, spacers springs or parts of a cable) and a possible whiplash of the broken  cable. 

REMOTE CONTROL PANEL 

The adjustment and control of the machine takes place via the classic control panel that can be remotely positioned with a 15 mt. long connection cable. It carries out all positioning, adjustment the machine, control and cutting operations. The remote-control panel is equipped with a convenient positioning stand and a box with a closing door. The switchboard is equipped with an emergency button.

RADIO REMOTE CONTROL (on request) 

The total adjustment and control of the machine can take place through the most innovative and radio safe remote control, from which it is possible to carry out all positioning, adjustment, and machine control and cutting management operations. The display allows you to view the cutting parameters.
