A vehicle fleet management information system for identification of location and direction of movement of each vehicle in the fleet in real-time and automatic communication directly with management offices to report its location and heading, and status of predetermined events in which the vehicle may be engaged. One example is a cement delivery truck which monitors location, speed and status information such as start pour, pouring, end pour, wash and leave job, and automatically transmits this information with a management office without requiring affirmative action by the vehicle operator.

A delivery unit for providing aggregate to a worksite, such as a wellsite location. The unit may include a mobile chassis for accommodating a plurality of modular containers which in turn house the aggregate. As such, a weight measurement device may be located between each container and the chassis so as to monitor aggregate levels within each container over time. The units may be particularly well suited for monitoring and controlling aggregate delivery during a fracturing operation at an oilfield. The modular containers may be of an interchangeable nature. Furthermore, a preferably wireless control device may be provided for monitoring and directing aggregate delivery from a relatively remote location.

To improve operability for vehicle height adjustment, while ensuring safety, in a vehicle such as a truck, a wireless remote control radio-transmits a vehicle height adjusting signal tagged with a remote control identification code. The remote control identification code is preregistered in a receiver, which, upon receipt of the vehicle height adjusting signal tagged with the remote control identification code, takes in the vehicle height adjusting signal. According to information contained in the received vehicle height adjusting signal, an air suspension ECU controls supply and discharge of compressed air for air springs to adjust the vehicle height. When an emergency operation switch is operated, the vehicle height adjusting signal from the wireless remote control is disabled, and vehicle height adjustment is preferentially made based on a switching signal from the emergency operation switch.

A trailer having support wheels and a frame adapted to be hitched to a truck, includes a support track extending longitudinally for supporting an unload conveyor. The conveyor is mounted by a turret to the support track and, thus, to the trailer frame, permitting the turret to move in a fore-to-aft direction, as well as to rotate about the vertical for about 180°, providing flexibility in use as well as transport and storage. A support module, carrying at least one storage container is mounted on the trailer frame. The storage containers may be provided in a number of different sizes and they may be arranged in various configurations suiting the user's needs. The turret is positioned along the track beneath a desired seed container, which may then be unloaded by the conveyor to fill a planter seed box or grain drill, or for other seed handling applications.

The present invention features a universal, low profile, expandable flow track system that can be drop-load mounted to almost any supporting frame or pallet rack. The flow track system of the invention features a flow track that mounts flush with its end supports, and is infinitely adjustable along both the horizontal axis and depth axis of the storage frame. The flow track is quickly assembled to, adjusted upon, and removed from, the storage frame.

A bulk seed handling system (20) is provided to facilitate seed transfer from a distributor to a farm and then to a planter or the like. The handling system (20) includes one or more upright bin assemblies (22) adapted to be moved in a filled condition, and a trailer (24) designed to move the bin assembly (22) and unload seed therefrom. The bin assembly (22) includes a seed bin (26) having a lower unload opening (34) and supported by a frame assembly (38) including telescopic legs (50) shiftable between a retractable travel position and an extended bin support position. The trailer (24) includes a lift frame (60) operable to engage and elevate the bin assembly (22) for travel with the legs (50) thereof in a retracted position, and a seed-conveying arrangement including an intermediate conveyor (62) and a delivery conveyor (64). At an unloading site, the intermediate conveyor (62) is shifted to an unloading position in communication with the bin unload opening (34) and the delivery conveyor (64) in order to transfer seed from the bin.

A roller unit that can be used to retrofit a cargo carrying surface makes loading and unloading of the cargo carrying surface easier by transforming the cargo carrying surface to include a conveyor system. The roller unit includes at least two trays in which are mounted rollers, the trays being connected by a crosspiece. The roller unit is designed to be installed on cargo carrying surfaces such as portable platforms, including Flatracks or CROPs, and in cargo containers of any type.

A method of transferring proppant materials, wherein the method includes providing a first pressurized container (102) containing proppant materials on a first vessel (106). The method also includes connecting the first pressurized container (102) on the first vessel (106) to a second container (102) on a second vessel (114) and transferring pneumatically, proppant materials from the first pressurized container (102) on the first vessel (106) to the second container (102) on the second vessel (114). Also, a method of transferring proppant materials, the method including removing a wellbore fluid comprising excess proppant materials from a well, and screening the excess proppant materials from the wellbore fluid. The method also includes transferring the excess proppant materials to a first pressurized container (102) and transferring pneumatically, the excess proppant materials from the first pressurized container to a second pressurized container.

A vehicle leveling system including at least one level sensor, a controller and an output. The sensor measures how level the vehicle is relative to horizontal. Optionally, it does so dynamically, as the vehicle moves across a potential parking area. The controller analyzes the sensor measurements, and informs the operator via the output whether the vehicle is level in a given direction, whether the vehicle is leveling, whether the vehicle can be leveled at a given location, and/or the “best” leveling that the system is capable of at a location. The system also may automatically level the vehicle relative to the ground for the operator. In one embodiment, the leveling system communicates with an existing vehicle electronic height control system. The leveling system overrides or controls the normal operation of this system, and uses it to level the vehicle, for example, by adjusting the vehicle suspension.

A first rotor (24; 124) and a second rotor (25; 125) are arranged in a coaxial and mutually rotatable relationship and are provided with a first driven gear (41; 141) and a second driven gear (42; 142), respectively. A drive shaft (31; 131) is also provided with a first drive gear (43; 143) and a second drive gear (44; 144) which are commonly connected to an output shaft of an electric motor (32; 132), and mesh with the first and second driven gears, respectively, at slightly different gear ratios. The first and second rotors are connected via a thread feed mechanism (36; 136) that converts a relative rotation between the first and second rotors into an axial linear movement between the first and second rotors that is used for changing a distance between a vehicle body part and a corresponding end of a suspension spring in a vehicle height adjusting system (9; 109). Owing to a differential rotation of a high gear ratio between the first and second rotors, a significant torque amplification is possible with a compact arrangement. The use of spur gears instead of a worm gear mechanism minimizes torque loss.

A motorized balance board includes a wheel rotation angle detecting sensor, a gyrosensor, and an acceleration sensor. An arithmetic operation unit calculates a rotation angle change value, a rotation angle value, a tilt angle change value, and a tilt angle value, based on signals output from the wheel rotation angle detecting sensor, the gyrosensor, and the acceleration sensor. When the control mode is a riding mode, a control mode switch element switches the control mode to a standby mode based on the rotation angle change value, the rotation angle value, the tilt angle change value, and the tilt angle value.

In this vehicular chassis system, the vehicle's passenger compartment and wheels incline toward the turning center side in such a manner, that the wheels can be tilted independently from steering. This vehicle has a steering apparatus controlling the steering, and a separate apparatus controlling the lateral leaning. The lean is controlled mechanically using a pendulum, and forced lateral leaned using a control unit, or manually with the transfer of body weight using several pinions with a set ratio to control the passenger compartment lateral lean in conjunction with the wheel lateral lean. An electric DC servo gear motor can be used to control the lateral lean, that intern moves a pinion, which moves a rack and lateral movable cross member, while controlling the lateral leaning wheels and pulling the tilt support bar pivotally attached to a passenger compartment in the same leaning direction.

An omni-directional wheel includes a hub rotatable about a wheel axis and a first row of angled rollers about the hub each rotatably supported by the hub. There is at least a second row of angled rollers about the hub each also rotatably supported by the hub. The rollers of the second row are axially offset along the wheel axis from the first row, and rotationally offset from the first row about the wheel axis, and not coaxial with the rollers of the first row.
