  • Gripper feed and gripper resilience cylinders on forging manipulators
    Patent number: 4420287
    Abstract: A forging manipulator has a mobile truck on which a gripper support is suspended by articulated linkages. To move the gripper support relative to the truck, and to provide cushioning of the gripper support, the gripper support is coupled to the truck by hydraulic cylinder assemblies. Each cylinder assembly includes three cylinders placed one above another with the piston of a middle cylinder connected to the truck and with the pistons of the outer cylinders connected to each other and to the gripper support.
