This disclosure includes a manhole cover locking device, system, and kit, each configured for locking a manhole cover in a closed position overtop an access opening of a container, the access opening being arranged at one end of a collar extending outwardly from the container, each comprising: a body; a mechanism for connecting the body to a pre-existing portion of the manhole collar or the container; and, a mechanism for securing the body to the manhole cover to prevent the opening of the manhole cover using a pre-existing portion of the manhole cover. Each mechanism may be tamper resistant. The disclosure also includes methods of installing and using the device, system, and kit.

A bulk material container can include a body, having a plurality of side walls, a bottom, a cavity, and an opening, and a first engagement element. The plurality of side walls are coupled to the bottom, and the cavity, which is configured to receive a bulk material, is formed within the plurality of side walls and above the bottom. The opening is formed by the plurality of side walls spatially opposite of the bottom and is configured to discharge the bulk material when the container is at least partially inverted. The first engagement element can be configured to receive one or more prongs of a transportation device or a bulk material unloading device. In some embodiments, the container may also include a second engagement element and/or a third engagement element, for example with the first, second, and/or third engagement elements differing from each other.

A method includes receiving, at a server, a first message including identifying information about a container with an access door seal being monitored by a first ARM device. The method includes initiating tracking of the shipment and first ARM device. The method includes, in response to receiving a second ARM device message indicating an unsealed status of the access door being monitored, comparing the actual time and location at which the ARM device detected unsealing of the access door to the expected unseal time and location. The method includes, in response to the actual time and location not being within a threshold range of the expected time and location, determining that an unexpected/unscheduled unseal event has occurred with the shipping container. The method includes generating and transmitting notifications alerting the operator and at least one interested party identified with the shipment of an unexpected/unscheduled unseal event.

A theft prevention device for a shipping container includes a channel and a plurality of magnets. The channel is defined by a base plate, a first plate, and a second plate. The base plate has a first side and a second side. The first plate extends from a first edge of the base plate in a longitudinal direction away from and perpendicular to the first side of the base plate. The second plate extends from a second edge of the base plate opposite the first edge of the base plate in the longitudinal direction away from and perpendicular to the first side of the base plate. The first plate extends away from the base plate farther than the second plate. The plurality of magnets is coupled to the first plate on a channel side of the first plate.

A method includes receiving a message indicating a status of an access door seal being monitored by a first ARM device deployed with a container to track a sealed/unsealed state of a cable locking mechanism affixed to an access door of the container. In response to the message indicating an unsealed/tampered status of the access door seal, the method includes: parsing the message for information related to time and location at which the ARM device detected unsealing of or tampering with the access door seal; and comparing the time and location to an expected time and location at which authorized unlocking of the container is expected. The method includes, in response to the actual time and location not being within a threshold range of the expected time and location, generating and transmitting notifications alerting at least one interested party identified with the shipment of the unexpected or unscheduled unseal event.

Secure storage carts are disclosed herein and capable of being assembled and disassembled on-site without common disadvantages that affect storage carts designed for on-site assembly. Secure storage carts disclosed herein may be assembled to a reduced tolerance, eliminating potential points of failure in the assembled cart, and giving the user a more solid feel to the operation. Methods for assembling storage carts are also disclosed herein and can include adjusting the extension depth of a door panel hinge. Methods disclosed herein also may include applying a preloading force to the cart frame, to reduce tolerances between components of the storage cart once assembled. Kits are also provided herein containing the components required to assemble the cart on-site, in configurations that may be easily transported to and from the job site when disassembled. Kits also may provide for straightforward and secure assembly of the carts.

An eco-friendly detachable container including a base assembly having a metallic plate attached to a support panel; telescopic corner posts; side panels; a top panel; a first door assembly; a second door assembly; a locking mechanism. The detachable container is vertically adjustable. The support pane, the telescopic corner posts, the side panels, the top panel, the first door assembly, the second door assembly, and the locking mechanism are made entirely from recycled plastic, virgin plastic, or regrind plastic. The metallic plate is made of a recycled aluminum.

A hatch cover includes spring-loaded exhaust and suction valves to regulate internal tank pressure with respect to outside pressure. The valves are disposed in a ring housing. The cover further includes a spring-loaded locking bolt configured to engage the hatch base and thereby provide a retaining force between the housing and the hatch base. The exhaust-valve springs may be selectively preloaded to establish a target exhaust pressure. The locking-bolt spring may be selectively disengaged or overcome to release engagement of the bolt from the hatch base.

A method includes receiving a message indicating a status of an access door seal being monitored by a first device deployed with a container to track a sealed/unsealed state of a cable locking mechanism affixed to an access door of the container. In response to the message indicating an unsealed/tampered status of the access door seal, the method includes: parsing the message for information related a location at which the device detected unsealing of or tampering with the access door seal; and in response to the location not being within a threshold range of the expected location, generating and transmitting notifications alerting at least one interested party identified with the shipment being transported of the unexpected or unscheduled unseal or tamper event.
