A dump trailer support assembly for supporting a belly dump trailer when the belly dump trailer is not coupled to a tractor includes a box for positioning on a support surface beneath a belly dump trailer. A shaft is slidably integrated into the box such that the shaft can be slid upwardly or downwardly in the box. A support is coupled to the shaft for supporting a bottom of the belly dump trailer when the belly dump trailer is not attached to a tractor. Additionally, the support is comprised of a magnetized material to magnetically engage the bottom of the belly dump trailer and inhibit the belly dump trailer from sliding on the support.

Provided is an assembly including a dump body configured to be supported by a frame to be moved relative to the frame between a dump position and a load position. The dump body includes first and second sidewalls, a front wall, a floor having a first opening, a tailgate, and an apron below the tailgate, the apron having a second opening substantially perpendicular to the first opening. The assembly also includes an endless conveyor configured to direct material to the second opening and being removably attached to the dump body below the floor such that material is prevented from exiting the dump body through the first opening.

A support arrangement for a haul truck comprises a space frame and a dump body operatively positioned on the space frame according to defined contact points. The space frame can include at least one rear support, at least one outer elongate support member, and at least one support rocker configured to pivot laterally about an axis. The dump body can include on a bottom thereof a rear pivot support and at least one flat contact surface, and on a front face thereof at least one vertical support structure. Each rear support of the space frame is configured to be pivotally coupled to the rear pivot support of the dump body. Each vertical support structure of the dump body is configured to be removably seated in a corresponding support rocker. Each flat contact surface is configured to be positioned adjacent to an outer lateral surface of an outer elongate support member.

A carrier for a planetary gear train includes a hub disposed about an axis of rotation, the hub having an external cylindrical surface including a plurality of splines extending along a longitudinal direction, the longitudinal direction being parallel to the axis of rotation; and a deck extending away from the hub along a radial direction, the radial direction being transverse to the longitudinal direction. The deck defining a plurality of holes therethrough, each hole of the plurality of holes being configured to receive an axle of a planet gear of the plurality of planet gears, the hub being disposed between the plurality of holes and the axis of rotation along the radial direction. The splines have a value of a parameter (P) that is not less than 2.5 and not greater than 6.0.

An article transport vehicle (V) includes: a carriage body (1); and a transfer device (3) that is mounted on the carriage body (1) and is configured to transfer an article. The transfer device (3) includes an article support unit (32); a linking support unit (31) that links the article support unit (32) to the carriage body (1), and a drive unit (D). The linking support unit (31) includes a first shaft support portion (311) that is linked to the carriage body (1) so as to be swingable around a first shaft (A1), the article support unit (32) includes a second shaft support portion (321) that is linked to the linking support unit (31) so as to be swingable around a second shaft (A2), and the drive unit (D) includes a first drive unit (33D) and a second drive unit (34D).

A method and system for monitoring operations of a machine operating at a worksite, is provided. The machine includes an implement for performing one or more implement operations and is powered by an engine. The method includes determining a first parameter corresponding to an engine speed associated with the engine, a second parameter indicative of vibrations detected inside the operator cabin and a third parameter indicative of a machine speed associated with the machine. The method further includes determining a machine operation as one of the loading operation, the dumping operation and a travelling operation based on one or more of the determined first parameter, second parameter and the third parameter.

A utility vehicle includes: a vehicle body frame including a cabin frame portion; a loading bed tiltable between a normal position and a dumping position; and an intake unit including an intake port. The intake unit is disposed above a rear wheel and extends over a height range overlapping a height range over which the loading bed in the normal position extends, and a location of the intake unit in a vehicle width direction substantially coincides with a location of a side wall portion of the loading bed in the vehicle width direction. The intake unit is located rearward of the cabin frame portion and exposed to the outside in the vehicle width direction. The intake unit is fixed to the vehicle body frame at a distance from a trajectory along which the loading bed is tilted.
