Device for controlling a container, particularly a bottom-unloading container

Abstract

Controlling a container, such as a spreader, is described for engaging, retaining, and moving containers, as well as for unloading containers, particularly bottom-unloading containers. A spreader includes a frame having mounted thereon twistlocks, an actuator, a movable engagement mechanism, and force transmission means connecting the actuator and the movable engagement mechanism. The actuator and the force transmission means are substantially disposed along the long sides of the frame, and the movable engagement mechanism is substantially disposed on the short sides of the frame. The actuator allows the movable engagement mechanism to move reciprocally primarily in a direction perpendicular to the plane of the frame. The spreader significantly expands the functionality of devices used for engaging, retaining, moving, and unloading containers, makes it possible to unload a bottom-unloading container, and also allows the automation, simplification, and acceleration of the unloading process of such a container.
