Abstract: Load cells are provided at the fixed end of each cable of a multiple-cable lifting head adapted for use at the free end of a knuckle boom or other aerial crane for lifting and operating "IGLOO" recyclable waste containers and the like. The load cells provided with each selectively controllable cable of the multiple-cable lifting head provide a signal through a J Box to a remote scale indicator at the base of the knuckle boom or crane in order to facilitate weighing the container at the beginning and end of the waste removal process so as to accurately determine the waste weight simultaneously with the removal thereof from the container.

Abstract: A mold guidance system for preventing horizontal movement of the mold of a concrete block making machine including, on each side of the machine, a mold support arm extending laterally outwardly from the inside corner of the mold and including a bushing in the outer end thereof, a first clamp secured to the side of the machine frame above the mold arm bushing, a second clamp element secured to the side of the machine frame below the mold arm bushing, and an elongate pin slidably movable within the mold arm bushing and fixedly engaged at the upper end by the first clamp and at the lower end by the second clamp. The mold guidance system prevents horizontal movement of the mold so as to reduce mold wear and increase mold life.
