Abstract:
A layer-picking clamp assembly supported by a truck, comprising:(a) a horizontally extending, hydraulically actuated, telescopically extendable and retractable boom pivotally mounted on said trucks so as to pivot horizontally with respect thereto;(b) a clamp, having opposed, downwardly depending clamps arms supported by said boom and capable of separately picking up and depositing individual layers of layered loads;(c) said clamp being vertically movable and horizontally extendable and retractable telescopically by said boom along multiple pivotal lateral directions at least in a 180.degree. range relative to said truck, said clamp also being movable by movement of said truck;(d) a right automatic pivot-stopping device that automatically stops lateral pivotal movement of said boom at a right position relative to said truck;(e) a front automatic pivot-stopping device that automatically stops lateral pivotal movement of said boom at a front position relative to said truck;(f) a left automatic pivot-stopping device that automatically stops lateral pivotal movement of said boom at a left position relative to said truck;(g) wherein said right and left pivot-stopping devices are at 90.degree. angles to said front pivot-stopping device.
