ABSTRACT:
A latch for the door of a module builder includes a plate attached to the door and a notched latch bar pivoted to the frame of the module builder. A hydraulic latch cylinder raises the latch bar at the same time pressure is applied to a main door cylinder to open the door. An orifice is placed adjacent to the main door opening cylinder to make certain sufficient hydraulic fluid is applied to the latch opener and also to limit the speed by which the door is closed. The latch cylinder is attached to a floating bar so that upon the door closing, the latch bar can rise to be latched closed even though the latch cylinder is closed.
