Abstract
A layer-picking clamp mountable on a truck has clamp arms extending downwardly from and movably mounted to an upper frame section. The clamp arms are linearly movable with respect to the upper frame section in laterally inward and outward directions so that gripping surfaces of the clamp arms retain their substantially vertical orientations as the clamp arms move inward and outward. The upper frame is supported on a first mounting apparatus that is positioned above a second mounting apparatus that supports a load-supporting device. The first mounting apparatus movably supports the upper frame so as to move the upper frame laterally and vertically with respect to the load-supporting device to enable the clamp arms to deposit a load on the load-supporting device. The load-supporting device is capable of supporting a pallet upon which the clamp can deposit the load. The clamp is supported on a laterally extending telescopically extendable and retractable boom pivotally mounted on the truck so as to pivot laterally with respect thereto. The clamp is vertically movable and laterally extendable and retractable by the boom along multiple lateral directions at least in a 180.degree. range relative to the truck.
