A fastener-free box with fast assembly is disclosed, comprising a baseboard, a front board, a rear board, a left board, a right board, and a cover board. An insert-connection structure that is configured to form an insert connection with a respective adjacent board is integrally formed on each of the board; any three perpendicular boards are configured to form an interlocking structure among them; and, a connection structure configured to couple with each other is integrally and individually formed on each of the cover board and the rear board. The structure of the box is simple. In addition, an interlocking structure can be formed after the box is assembled, enabling an even more robust box structure. Furthermore, the box is ideal for outdoor use as it is water proof.

A dump both for a working machine includes two main plates for creating a load receiving surface. The two main plates are joined to each other by a weld joint. The dump body includes a backing plate arranged on the two main plates at the inside of the dump body. The backing plate covers the weld joint and is joined to the two main plates by the weld joint.

An exemplary approach for protecting floorings in containers may utilize a first ledger attached to an upper portion of a first support beam associated with a foundational base assembly. A portion of the first ledger may protrude outward in a first horizontal direction from the upper portion of the first support beam. A second ledger may be attached to an upper portion of a second support beam next to the first support beam. A portion of the second ledger may protrude outward in a second horizontal direction from the upper portion of the second support beam. The second horizontal direction may face the first horizontal direction. A support panel may be placed on top of the portion of the first ledger and the portion of the second ledger. The support panel may have a length proximate to a distance between the first support beam and the second support beam.

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.

The present disclosure relates to liners and methods of making liners. The liners may be suitable for use with tanks and other storage/containment vessels, such as process tanks, immersion tanks, indoor or outdoor containment pits, gravity feed conduits (e.g., concrete trench, canal, or drain, etc.) for transferring or conveying liquid, grain storage tanks or containers (e.g., dielectric or electrically non-conductive liners for grain storage, etc.), etc.

A parts assembly, a tank, and a panel discussed, including a first wall; a second wall, a first edge of the first wall facing a second edge of the second wall; a first flange connected to and extending outward from the first wall; a second flange connected to and extending outward from the second wall, the second flange being spaced from and disposed opposite the first flange; at least one fastener extending through and connecting the first flange and the second flange, the at least one fastener being pre-tensioned; and at least one rigid spacing member disposed between the first flange and the second flange, the rigid spacing member being spaced from the at least one fastener, the rigid spacing member being in contact with the first and second flanges, the at least one fastener being disposed between the rigid spacing member and the first and second walls.
