Cylinder, double-acting, with two piston rods and single trestle

This twin cylinder has two in and out piston rods that move in parallel and that are coupled by a 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.
