A trailer for transporting a container has a frame mountable to a vehicle. The frame has a rear frame section mountable above a rear wheel assembly of the trailer, and a front frame section connected to and disposed forward of the rear frame section in a forward direction of travel of the vehicle. The front frame section has a king pin mountable to a hitch of the vehicle and a forward-most end. The forward-most end is moveable relative to the kingpin in a direction parallel to the forward direction of travel to extend and shorten a length of the front frame section between a fully-lengthened configuration and a fully-shortened configuration.

The chassis assembly (3) includes a vehicle chassis (4) extending along a longitudinal direction (D1); a first supporting part (6) configured to support a first load unit (7.1) on a first longitudinal side (4.1) of the vehicle chassis (4); a second supporting part (8) configured to support a second load unit (7.2) on a second longitudinal side (4.2) of the vehicle chassis (4) opposite to the first longitudinal side (4.1); and a lifting device (5) secured to the vehicle chassis (4) and configured to lift up and down the first and second supporting parts (6, 8) with respect to the vehicle chassis (4) so as to vertically displace each of first and second load units (7.1, 7.2) supported by the first and second supporting parts (6, 8) between a loading/unloading position and a driving position.

An apparatus for delivering proppant to a well site includes a plurality of proppant containers. The apparatus also includes a support structure having a bed and a structural framework extending down from the bed. The plurality of proppant container are structurally supported on top of the bed. A bin is disposed within the structural frame work below the bed. A conveyor cooperates with the bin for transporting proppant from the bin to a desired location at the well site. Proppant discharged from one or more of the plurality of proppant containers positioned on the bed above the bin is received in the bin and delivered to the well site by the conveyor.

An agricultural implement for mounting on a U-shaped foundation frame supported on wheels for travel over a ground surface where the foundation frame includes first and second laterally spaced mounting beams fixed to and extending from a base. The implement is configured to perform an agricultural operation, to rest on the ground surface when in an idle position, and to attach to the foundation frame when in an operating position. The implement comprises a rigid implement portion configured to be attached to the first and second mounting beams at first and second beam locations remote from the base such that the first and second mounting beams are prevented from moving laterally with respect to each other.

A locker configured to store a package is disclosed. The locker includes a storage compartment, a door to the storage compartment, and a securing component attached to the storage compartment. The securing component actuates between a secured position and an unsecured position.

The chassis assembly (3) includes a vehicle chassis (4) extending along a longitudinal direction (D1); a first supporting part (6) configured to support a first load unit (7.1) on a first longitudinal side (4.1) of the vehicle chassis (4); a second supporting part (8) configured to support a second load unit (7.2) on a second longitudinal side (4.2) of the vehicle chassis (4) opposite to the first longitudinal side (4.1); and a lifting device (5) secured to the vehicle chassis (4) and configured to lift up and down the first and second supporting parts (6, 8) with respect to the vehicle chassis (4) so as to vertically displace each of first and second load units (7.1, 7.2) supported by the first and second supporting parts (6, 8) between a loading/unloading position and a driving position.

A container has an anti-vibration property so that the container does not shake in vibration. The container includes a bottom part, a ceiling part facing the bottom part, a sidewall part connecting the bottom part to the ceiling part, and a rack installed to be fixed in an inner space that is surrounded by the bottom part, the ceiling part, and the sidewall part.

A cargo loading system for a cargo vehicle includes a carrier device provided in a loading space of the cargo vehicle to move cargoes in the loading space, a setting unit configured to set a loading position for each cargo in which each cargo is located in the loading space of the cargo vehicle based on basic information of each of the cargoes, and a control unit configured to control operation of the carrier device according to a loading position of a corresponding cargo set in the setting unit when the corresponding cargo is loaded on the carrier device so that the corresponding cargo reaches the loading position matching the corresponding cargo.

A system for parcel delivery may be provided using a package Pickup and Receiving Stations (PRS), sometimes also referred to as a Hub or Local Automated Hub. In some applications, it may be desirable to provide a number of PRSs located in areas having a high volume of local package delivery. Parcels directed to a recipient within an area serviced by the PRS may be delivered in bulk to the PRS by a parcel carrier. The PRS may then attend to final delivery to each parcel's recipient, preferably using an automated ground vehicle (AGV). Additionally or alternatively, consumers may tender packages to an AGV for, e.g., subsequent retrieval by a package carrier for further transport.

A method is disclosed for handling a first dumpster and a second dumpster. The method comprises the steps of lifting the first dumpster from a lower dumpster holding channel to an upper dumpster holding channel. The lower dumpster holding channel, the upper dumpster holding channel and the first dumpster are pivoted relative to a rear chassis. The second dumpster is positioned into the lower dumpster holding channel. An angled dumpster displacement channel is extended from the rear chassis. The first dumpster is lowered from the upper dumpster holding channel and along the angled dumpster displacement channel. The lower dumpster holding channel, the upper dumpster holding channel and the second dumpster are pivoted relative to the rear chassis.
