<p>The jaws (18) for pallet handling equipment are each pivoted about a point (16, 17) mounted on pillars (12, 14) on the frame. The top sides of the jaws are joined by a helical spring (32) which keeps them apart. Two links (20, 21) pivoted at the same points are connected by a pin (23) riding in a slot (22). A second lever (24) is pivoted at the same level at an outside point (25). The inner end of this lever is retained by a spring (31). The jaws are locked closed by the spring loaded levers operating from the cell (34).</p> |
