In general, drum tilting apparatuses are somewhat complicated or not adapted to hold a drum in a variety of emptying positions. A relatively simple drum tilting apparatus includes a skeletal, rectangular frame carrying a pair of parallel, spaced apart tracks, which slidably receive rollers on the top inner end of a semi-cylindrical carriage; a catch on the carriage for releasably retaining a drum on the carriage; a pair of generally triangular arms pivotally connected at one corner to the carriage and at a second corner to the base of the frame; a pair of hydraulic cylinders pivotally connected to the base of the frame between the drum loading position and the bottom corners of the arms; and piston rods extending out of the cylinders to a shaft extending between the third corners of the arms so that the arms can be rotated around a horizontal axis to move the carriage between drum loading and drum tilting or emptying positions. |
