20090085394 | BELLY DUMP TRAILER - A belly dump trailer including a hopper having sides made up of multiple hollow extruded aluminum panels. Cones are attached at forward and rearward ends of the hopper. The cones are made of aluminum. The cones are hollow and each cone includes internal stiffener rings supporting an outer shell. The hopper sides include top, side and bottom rails interconnected to the panels. Each of the top, side and bottom rails is made of a hollow extruded aluminum. Another belly dump trailer includes a hopper and a cone attached to the hopper, the cone having an axis which is inclined downwardly in a direction away from the hopper. Another belly dump trailer includes a hopper having first and second side walls each made up of multiple hollow panels, and front and rear walls; a first cone attached to the front wall; and a second cone attached to the rear wall. | 04-02-2009 |
20100270848 | APPARATUS FOR OPENING HOPPER DOOR - A hopper door opening and closing apparatus uses a pneumatic cylinder to open and close the sliding hopper door. A control valve maintains pressure on both sides of a piston within the pneumatic cylinder to provide a smooth operation of the door opening and closing process. | 10-28-2010 |
20100308638 | BULK MATERIAL HANDLING VEHICLE - A vehicle including a chassis ( | 12-09-2010 |
20110198911 | STORAGE HOPPER ASSEMBLY - A transport assembly for transporting granular material may define at least a first egress for releasing a first portion of a granular material. The device may also include a door assembly slidably coupled with the transport assembly for at least substantially covering the first egress in a first position for retaining granular material and for at least substantially uncovering the first egress in a second position for controllably releasing the first portion of the granular material. The device may also include a linear actuator assembly coupled with the transport assembly and the door assembly for moving the door assembly between the first position and the second position. The device may also include a pump assembly coupled with the linear actuator assembly for actuating the linear actuator assembly to move the door assembly between the first position and the second position. | 08-18-2011 |
20140001818 | GRAVITY WAGON WITH DISCHARGE CHUTE AND KICKBACK | 01-02-2014 |
20140327291 | Modular Hopper Unit for Bulk Material Transport Truck or Trailer - A bulk material transport apparatus which includes a containment structure on a wheeled frame which is formed of perimeter wall members about a bulk material containment area, further includes at least one modular hopper unit mountable at a bottom side of the containment area for discharging contents of the bulk material containment area therethrough. The modular hopper units can be readily interchanged with other hopper units which are different in gate opening size, gate opening height, gate opening orientation, and/or other characteristics relative to one another. One optional modular hopper unit is a side discharge unit which is reversible for discharging to a selected one of two laterally opposed sides of the transport apparatus. | 11-06-2014 |
20150115688 | TRAILER FOR TRANSPORT OF FRACKING SAND - An assembly for a fracking sand trailer wherein a door can be positioned to allow a measured flow of sand to exit the assembly. The assembly can be attached to a hopper of a trailer and can stand the weight of heavy loads associated with sand. A trailer with the assembly is also described and utilizes specific construction techniques to lighten the weight of the trailer. | 04-30-2015 |

20120068522 | AUTOMATED GATE CONTROL AND METHODS - An automated gate control system for a vehicle with a load carrying portion capable of carrying a load of material selectively distributable through a gate comprises a driver-accessible control module and a gate actuating mechanism. The driver-accessible control mechanism is positionable within reach of a driver of the vehicle. The gate actuating mechanism is controllably linked to and responsive to control signals from the driver-accessible control module to open and to close the gate to distribute material through the gate as desired. As a result, the driver need not exit the vehicle to move the gate before, after or during a material distribution operation. | 03-22-2012 |
20150336496 | BELLY DUMP TRAILER - A belly dump trailer has a hopper having a bottom gate and a mobile support frame. The belly dump trailer is supported by wheels which may be in a dual axle configuration. The bottom gate is rotated between an open and closed position to discharge a load of materials within the hopper. The bottom gate is driven by a rotary drive connected to the bottom gate by an over center cam lock formed of pivotally connected link arms. The opening and closing of the bottom gate is driven by a pair of pneumatic linear actuators. The bottom gate may be positioned in between the two axles of the dual axle configuration. | 11-26-2015 |
