Abstract
A linkage clamping system that may be used both for moving a clamp laterally and for rotating the clamp. The device includes a linear actuator, a rotational linkage assembly, and a clamping member. The linear actuator may first rotate the clamp, then move the clamp laterally, or may be configured to move the clamp laterally first, then rotate it. Both the lateral and rotational movements are achieved in distinct motions with a single linear actuator. The clamp may be rotated about 180 degrees and the lateral movement may only be limited by the lateral movement provided by the linear actuator. The linkage clamping system may be used to secure equipment, such as a material handler for unloading an open top railroad car.
