A wheeled shipping/transport cart includes a cart frame that supports a plurality of wheels. The cart frame supports a plurality of stackable trays. The trays include a tray frame with opposed end members, a plurality of longitudinal support members disposed between the opposed end members, and a plurality of upright members nesting with upright members of an adjacent tray. A support structure is disposed between the opposed end members to form an arc corresponding to a curved surface of an article to be supported by the support structure. A pin is received through each of the upright members of the plurality of stackable trays to retain the stackable trays in a stacked configuration.

This disclosure is directed toward a heated tailgate for use in cold climates. The heated tailgate may be used with a self-contained heated portable vacuum slurry box. The slurry box generally includes a vacuum tank, a structure attached to the tank, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The heated tailgate provides that the slurry cuttings within the slurry box which are adjacent to the tailgate do not freeze and provides for a way in which the tailgate may seal to the vacuum box.

A modular cargo storage system (CSS) is described for use on a base platform of a modular autonomous bot apparatus that transports an item being shipped. The modular CSS includes a set of folding structural walls, an interlocking alignment interface on at least one of the walls, and a modular component power and data transport bus. The walls at least partially enclose a payload area above the base platform. The interlocking alignment interface has a set of latches and a locking handle coupled to the set of latches that actuates the latches to interlock with the base platform. The power and data transport bus have top and bottom side modular component electronics interfaces where each interface has a power conduit outlet and a command and data communication interface.

A container for transporting and storing landscaping materials includes a rectangular container body having a bottom wall, a pair of side walls, and an end wall which define an open-ended chamber; and a vertical ramp end wall that is pivotally displaceable between a normal vertical closed position, and a downwardly inclined loading position, which pivot arrangement includes a pair of horizontal pivot shafts arranged collinearly transversely of the container on opposite sides of the protruding ends of a pair of guide rails that extend longitudinally beneath the bottom wall. To afford manual operation of the massive ramp wall, a counter-balancing spring arrangement is provided including a pair of torsion springs mounted concentrically on these two pivot shafts for biasing the ramp wall from the loading position upwardly toward the closed position with an aggregate torque force that is generally equal to the weight of the ramp wall.

A heated slurry transport system for receiving, transporting and unloading a cuttings slurry in a non-frozen manner in cold weather environments. The heated slurry transport system generally includes a portable tank having an interior surface, at least one wall, and a rear door. A layer of insulation surrounds at least a portion of the portable tank to help retain heat within the portable tank. A heating unit is attached to the portable tank and adapted to heat a fluid that is transferred through at least one heat loop attached to the portable tank to heat the interior of the portable tank and the contents of the portable tank.

Methods are described that perform a dispatched consumer-to-store return or swap logistics operation for an item being replaced using a modular autonomous bot apparatus assembly and a dispatch server. The method begins with receiving a return operation dispatch command that includes identifier information, transport parameters, and designated pickup information for the item being replaced/returned, along with authentication information related to an authorized supplier of the item being replaced. Modular components of the bot apparatus are verified to be compatible with the dispatched logistics operation. The MAM then autonomously causes the bot apparatus to move to the designated pickup location, notifies the authorized supplier of an approaching pickup, receives supplier authorization input to permissively allow access to a payload area within the bot apparatus, monitors loading as the item being replaced is received along with return documentation, and then autonomously causes movement of the bot apparatus back to the origin location.
