Bm-dragon multiblade gangsaw 80/800 has the characters of:

A blade stoke of 800mm facilitates the evacuation of slurry which results from the sawing of marble and, in particular, of non-crystalline materials, preventing the blades from clogging while ensuring a high quality cut. This is particularly important when sawing defective and fractured blocks.

An 800mm stroke also means fewer cycles/minute and consequently less mechanical stress on the relative components.

Articulated rectilinear guides

Movement of blade holder frame on articulated guides.

This system reduces to a minimum problem of the blade holder frame. It greatly reduces maintenance costs because it does not require replacement like the traditional slideways which are subject to continuous wear.

Equal distribution of mechanixal thrust over all machine components

Advantages of two connecting rods:

All the energy and mechanical thrust towards the blade holder is spread on two connecting rods and two cranks instead of just one.

The two connecting rods which are attached to the extremes of the blade holder help the articulated guides to ensure that it's movement remains perfectly rectilinear without any deviation. This is especially important when there are more blades on one side of the frame(the machine applies greater pressure where there are more blades), and when the blocks are of different heights(because initially more pressure would be applied on the higher block).

The rotating lead nuts which worm screws of the block trolley platform are situated above the columns and lubricated automatically.

Battery unit

Details of the battery unit. The battery supports have been designed to allow easy maintenance and facilitate the replacement of the roller bearings without having to break the cement foundations. The flywheel weights 8 tons and has a diameter of 3300mm
