GS 121 OPEN FRAME GANG SAW
This machine, that was designed for the quick sawing of marble irregular blocks, represents the synthesis of the best technical solutions extensively experienced by Alpe and the most advanced manufacturing technology used to day by Pedrini.

The closed frame gang saw can cut marble slabs of various thickness. The closed frame gang saw is realized to install from 80 up to 100 diamond blades. The closed structure means that the blade holder frame is not moving up and down, the vertical movement of the block is given by n.4 worm screws connected to the block trolley.

The rectilinear movement is given on 4 articulated rectilinear guides attached to the closed frame structure. These rectilinear articulated guides vastly reduce maintenance costs because they do not require replacement like the traditional slide ways which are subject to a continuous wearing. The best solution for higher speed , more accuracy and precision is one where the connecting rods move together with the blades horizontally along a single axis only. This means there is no dispersion of mechanical thrust in other directions. The block is stable when fixed on the upward moving platform. The platform runs on 2 plane and 2 prismatic vertical slide ways. These plane and prismatic slide ways prevent any deviation or tilting away from the vertical axis. The trolleys are entering laterally and frontally. The 80 and 100 models have a linear stroke of the blade of 800 mm or 1000, the longer stroke guarantee a bigger production

​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 weighs 8 tons and has a diameter of 3300 mm.



STRAIGHT ARTICULATED GUIDES



The blade holder is made of steel plates joined solidly together, each of which has a section of 800x60 mm, and slides on straight articulated guides that are practi-cally maintenance free.



THE CONNECTING RODS



Equal distribution of mechanical thurst 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.



BIG CUTS IN ALL SAWING COSTS!



ELECTRICAL POWER



Lower electrical power consumption thanks to:



A - Direct motor flywheel transmission by V-belts



B - Hydraulic coupling to compensate for dead times and facilitate start-ups



C - 3.300 mm diameter - 8 ton flywheel



D - Electronic emergency brake, which together with the hydraulic coupling permits fast machine stop while protecting the motor (optional)



E - “SCR” power control system (optional)



MAINTENANCE



Major points of wear eliminated thanks to:



A - Articulated rectilinear guides



B - Stainless steel parts



C - Less stress on all moving parts thanks to the 800 mm stroke and the reduced number of cycles/minute.



DIAMOND BLADE YIELD



Blade yield increased thanks to:



A - The lengthening of the blade-holder stroke to 800 mm, which facilitates the removal of the mud produced during sawing



B - The new open-duct water sprikling system, ensuring more homogeneous water distribution



C - Fewer cycles with reduced inversion of the diamond tool



BM for Breton - Diamond-bladed saw for marble with block raising



Entirely made and assembled in Italy with european parts and first-rate international components.
