Machinery Function Features:
Chain saw on which all drives are electric and controlled by Inverters. The higher energy efficiency with respect to hydraulic systems and the specific tool arrangement offer significantly better cutting speeds and tool life.
A modern heavy-duty chain saw for sedimentary stone quarries,where the machine can perform cuts both vertical and horizontal.
The machine is driven entirely by electric motors to reduce energy demand (due to the higher efficiency with respect to hydrostatic transmissions) also eliminating maintenance problems typical of hydraulic circuits.
The machine consists of the following main parts:
The welded steel frame is extremely rigid in both torsion and bending to ensure the absence of deformation guaranteeing limited mechanical loads on the cutting arm and long tool life.
The main 30 kW motor operating at variable speed under the control of an Inverter, driving the chain itself, through an epicycloid gearbox.
The blade rotation system, also with a variable speed motor (Inverter controlled) and an irreversible double worm and crown gearbox for blade rotation;
The motorised blade-swing system, with a 0,75 kW Motor that positions
the blade horizontally or vertically.
Variable speed 3 kW motor with a speed reducer and rack and pinion system, to drive the machine along the track.
A pump set for blade pinion and chain lubrication, with 0,25 Kw motor
The electric panel and switchboard with controls and commands with emergency machine stop in case of anomalies.
- a set of inverters for the main motors - a cutting speed control system
- all manual and automatic controls - current absorption on all motors control system - safety and emergency protection devices
Available in lengths suitable for cutting depths from 2 to 5.6 m, the blade is in special high strength and wear-resistant steel. The blade incorporates channels for both lubricant pipework and for cooling water or air.
The blade edges are machined and drilled to house the wear-plates on which the chain runs during cutting; these replaceable plates are in hardened and tempered steel.
The special steel chain consists of 8 tool-carrier links. The first 5 links carry one tool, while the others each have two in stepped positions.
This patented arrangement offers high cutting speeds and the best possible resistance to tool wear and breakage. The tools are normally in Tungsten Carbide size 12,7 x 12,7 x 6,5mm and are fastened by a screw so that each tool can be used up to eight times
Three tracks are provided (more on request) each of 3m length, and complete with anchoring systems to fasten the machine to the quarry floor.
The three-track system allows continuous machine operation; when track 2 is reached, track 1 can be placed ahead of track 3, with no need to stop the machine.
Walking beam type track
A "walking beam" version is also available with a single track of length 7.5m, allowing 5m travel. Using hydraulic cylinders, the machine can be lifted with the track, the latter then being shifted ahead to continue cutting, with no need for other lifting gear.
A large increase in quarry output can be achieved by combining the use of a chain saw and diamond wire saws.
