The hydraulic shears OMAG mod. GHB are built from 3 to 8 meters of length with a cutting capacity from 6 to 30 millimetres. The cylinders are at double acting and they are made in steel and lapped; shafts are in steel and ground. The blade holder runs on a vertical table and it is directly controlled by the two standard cylinders and it is driven by a roller bearing system. The hold down pistons are independent therefore the tightening force adjusts itself automatically in relation to the sheet thickness to be cut. Both the blades, top and bottom, are with 4 cutting edge wires. The adjustment of cutting angle at hydraulic driving is carried out by acting on two levers placed outside the housings. The shears model GHB has in the standard equipment the numerical control CPC123 for one axes that reduces and simplifies the working process.
