ABSTRACT:
An automatically actuated hydraulically powered vibrator system for loosening the contents of a semi trailer dump body so that it will break away at its natural dumping angle. The semi trailer dump includes a hydraulic pump which delivers hydraulic fluid under pressure to extend a telescoping hydraulic cylinder to raise the dump body to a dumping position. An adjustable normally closed pressure relief valve is set to open when the pressure in the cylinder reaches a predetermined level corresponding to a dump body angle a few degrees less than the normal dumping angle for the commodity being dumped. When the valve opens, hydraulic fluid is pumped to a hydraulic motor which drives a vibrator which is bolted to the dump body. The vibrator loosens the material being dumped and prepares it to slide out of the body at its natural dumping angle. When slide-out begins, the fluid pressure in the cylinder drops, the valve closes and shuts off the hydraulic motor and vibrator, so that the material being dumped slides out of the dump body naturally.
