Automatic stall clamp for cattle - has spring loaded locking arm biased into closed position and opened for use by pulling cable

摘要

The automatic clamp is used to hold cattle in their stalls and comprises two vertical tubular sides (15), each connected by a short chain linkage (24) to a two-part arm (22) having a central hinge (28). The opposite ends of these sides are connected to a common horizontal link bar (12) by means of arms (13) extending downwards to pivots (25) on the sides. This link bar has an additional spring loaded locking arm (50, 53) biased into the closed position. A cable (58) is provided, this being pulled when it is required to release the locking arm for use.
