Cylinder, double-acting, with two in and out piston rods and double trestle
This twin cylinder has two in and out piston rods that move in parallel and that are coupled by a double trestle. The construction guarantees minimum torsion when positioning and moving tools or assemblies. Moreover, coming along with the same construction height, the double piston rod conveys the double force as compared to standard cylinders.
