Abstract: A drive across low-profile portable hydraulic trailer dumper for dumping the contents from a trailer containing a dumpable material, includes a towable elongated frame. A base frame with a deck pivotally attached hereto, which closes down and interlocks with the base frame. Making the overall height of the lift deck only seven (7) inches above the ground or pad site. Removable tread plates for use, when pulling a tractor and trailer forward, onto the trailer dumper. The lift deck has an adjustable chock for positioning the trailer during dumping. Actuators raise and lower the deck between a lowered position adjacent the base frame and a raised position for dumping the trailer contents. The trailer dumper has opposing cantilever wheels located near the back end of the dump for lowering a back end base frame to the support surface at the dump site, and raising a back end of a trailer dumper for towing.

Abstract: A dredge having substantially a box-like shape, with an open front face and an open rear face, the rear face having a door hinged thereto and a lock member to hold the door in a locked position. An A-shaped frame member is pivotally secured to the front end of the dredge. Pivotable motion of the A-frame raises the front edge of the dredge over an obstruction. A pulley assembly is secured to the rear top end of the dredge, and a cable from the A-frame is placed over the pulley when the A-frame is to be pivoted to raise the dredge. A door is hinged to the rear side of the dredge. A locking hinge is secured to the rear of the dredge to lock the door in a closed position. The locking hinge includes a pivoting edge, which engages the top edge of the door, and a rectangular bar secured under the locking hinge. The rectangular bar has a width greater than the height so that rotation of the bar produces a pivoting motion of the locking hinge to unlock the door.

Abstract: A portable low-profile tipper for dumping the contents from a trailer containing a dumpable material, includes a towable elongated and angled frame having a portion resting on the ground during dumping for greater stability. A deck is pivotally attached at an elevated position to the frame back end. The deck has a backstop for positioning the trailer during dumping. Actuators raise and lower the deck to dump the trailer contents. The tipper has a chute with fixed and pivoting components cooperating to guide the dumpable material from the trailer past the frame back end. Front and back stabilizers extend outwardly from the frame. The front stabilizers lift and lower the frame front end between a low-profile dumping position and a raised towing position.

Abstract: A truck platform is elevated at one end and then moved rearwardly by pulsation cylinders which slowly accelerate and then rapidly decelerate the platform and truck. The abrupt deceleration causes the material in the truck to continue to move rearwardly separating from the truck floor and move out of the truck in a stair step fashion through repeating pulsations. The angle in which the platform needs to be raised is minimized by the application of pulsation forces to the system thereby improving the safety and ease of unloading the truck.
