Abstract: Material handling solutions for a mobile conveyor vehicle are provided. In one aspect, a vehicle having an infeed and output conveyor is provided, one of the conveyors being mounted non-rotatably to the vehicle and positioned by rotation-in-place of the vehicle via four wheel steering. In another aspect, a dust control cover for a telescoping conveyor is provided, having a pair of flexible flaps which are parted by a plough-shaped chute which travels through a gap between the flaps and delivers material to the lower conveyor section. In another aspect, a hydraulic fluid transmission system for a mobile conveyor vehicle is provided which makes use of at least one hollow structural element to route the hydraulic fluid. The structural member may radiate heat from the fluid for example to melt snow on the vehicle structure.

Abstract: A method and system for handling granular material, such as proppant used in hydraulic fracturing in well drilling, is provided. In an operational configuration, a delivery module having conveyors receives and conveys granular material to a delivery location, and one or more mobile storage modules receive, hold and dispense granular material downward to the delivery module. The mobile storage modules comprise a raised, angular container portion for holding granular material. Each module may comprise a rock-over chassis for support against ground. In a transportation configuration, each of the delivery modules and mobile storage modules are separately transportable as semi-trailers. System redundancy features such as hydraulic power packs are also provided for.

A remote control module provides centralized, remote control of the system. Mobile support unit modules may also be provided as a remotely controlled vehicle capable of providing power, control, heating, and the like to other modules. Mobile in-feed elevator modules may also be provided as a remotely controlled vehicle for feeding granular material to mobile storage modules. In a transportation configuration, each module is separately transportable.

Abstract: A vehicle side dumping apparatus is provided comprising a pivotable deck for supporting and tipping a vehicle, and one or more piston-cylinder assemblies configured for tipping the deck. A piston rod of each piston-cylinder assembly has a first end pivotally supported against a support surface. A coupling assembly mechanically and pivotally couples the deck to the cylinder at a coupling location of the cylinder, wherein the coupling assembly is configured to substantially axially load the piston-cylinder assembly. The coupling location is located near the cylinder end receiving the piston rod, substantially in line with the vehicle deck, the remainder of the cylinder extending above the vehicle deck.

Abstract: The remote controllable material handling system comprises a material handling device configured to carry particulate matter, which includes one or more operatively coupled actuators, wherein the actuators are configured to transfer the particulate matter carried by the material handling device and are responsive to one or more control signals. The remote controllable material handling system further includes a MHD receiver operatively connected to the material handling device, which is configured to generate the one or more control signals in response to one or more transmission signals originating from a wireless remote transmitter. The wireless remote transmitter is moveable relative to the material handling device, and configured to receive as input one or more operator instructions for generating the one or more transmission signals for transmission to the MHD receiver in response to the one or more operator instructions.

Abstract: The present invention provides a rollover limiting vehicle coupling apparatus for coupling two vehicles, wherein apparatus is configured to provide stability in certain directions in one mode of operation, and is further configured to prevent transmission of rollover between vehicles in another mode of operation.

Abstract: A trailer unloading system anchors one or more trailers to a deck, with, or without tractor attached. The sides of the trailers are free to pivot from a top, longitudinal, pivot axis once unlatched from the edge of the trailer floor. The deck tilts the trailers sideways, the doors swing free, and the load discharges. The deck returns to level, the sides latch to support the floor and the trailers are ready to be reloaded.

Abstract: A connector system for coupling a suspension frame device to the rear part of a transport trailer for use in distributing the weight of the load of the trailer to extra wheels and/or providing an effective attachment arrangement for connecting a second trailer behind the first trailer in tandem fashion. The connector system includes a part formed at the front of the suspension frame device which includes a rigid frame portion carried by an additional set or sets of wheels, and the connector system further includes a second part formed integrally at the rear of the frame of the first trailer, the two parts having mating guiding portions for properly aligning the suspension frame device with the trailer as the parts come to an initial hitching position.

Abstract: A versatile and easily serviceable material spreading apparatus of the type for movement over a ground surface while broadcasting a material along a path on the ground surface. The apparatus includes a belt cartridge which can be slid into or pulled out of a chassis compartment having ledges for supporting the cartridge. The belt cartridge provides an upper flight on which material is carried from a hopper supported on the chassis to a broadcasting unit carried at one end of the chassis. A plurality of broadcasting units each of which has an attachment component, which in combination with a mating attachment component carried by the chassis, permits quick fastening and removal of each unit relative to the chassis. One of the broadcasting units mounts an elongated rotatable member below a drop-offend of the upper flight of the belt cartridge, and the rotatable member is driven in a direction so that the upper rotating periphery of the rotating member propels the material upward and away from the chassis.
