A retractable container cover system includes a container, a track, a cover, and an actuation mechanism. The container includes a plurality of sides, a bottom, and a cavity defined by the plurality of sides and the bottom. The track is coupled to one of the plurality of sides of the container. The cover includes a first end. The cover is further configured to be slidably received by the track and move between a deployed position and a retracted position. The actuation mechanism is coupled to a first side of the plurality of sides of the container. The actuation mechanism is configured to cause the cover to move between the deployed position and the retracted position. The cover encloses the cavity of the container when in the deployed position.

A system for opening a lid of a bin comprises a guide channel plate comprising an elongated member, a first guide channel comprising a first slot formed within and along the length of the guide channel plate, and a second guide channel comprising a second slot formed within and along the length of the guide channel plate and parallel to the first guide channel slot. A block plate fits within the first and second guide channels and is secured by a block plate clamp. The block plate connects to a linear actuator that is secured to a support member of the bin. A slide block fits compressively within the first and second guide channels thus securing a flexible link assembly and wherein the slide block connects to the linear actuator. A connector plate allows connecting and disconnecting of the linear actuator.

An unloader for a shipping container includes a supporter having a frame structure and a pallet base supported by the frame structure and configured to receive the pallet and support the shipping container in an elevated position. A gate moving mechanism is supported by the pallet base and configured to engage the moveable gate assembly when the full shipping container is positioned onto the pallet base. A material director has a first end located beneath the pallet base subjacent of the gate moving mechanism. The material director extends downwardly from the pallet base and terminates at a second end opposite the first end. Bulk material is dispensed from the shipping container into the first end and is discharged from the second end of the material director. Shipping containers may be positioned onto and removed from the pallet base without disassembly of the unloader.

The present invention discloses a container, comprising a container body and a lid, the container body comprises a base and side plates, the lid is provided with a first hanging-against structure, the side plate is provided with a second hanging-against structure cooperating with the first hanging-against structure, the first hanging-against structure and the second hanging-against structure are separatable to achieve hanging-against and removal of the lid, the lid is slidable above the container body whereby the first hanging-against structure and the second hanging-against structure are brought close to or away from each other, wherein the first hanging-against structure is slidable along the lid for a certain distance so that the position of the center of gravity of the lid changes relative to the first hanging-against structure. The present invention can realize the multi-directional hanging function of the lid and the container, with novel and reliable structure, simple and convenient operation, solid and durable.

An access control device for controlling access to a tank defining a storage chamber and access to the storage chamber; the device includes at least one cap and an external apparatus; the cap includes a closure body defining a closed position and an open position; a housing defining a housing volume for the closure body and a reciprocal rotation with respect to the closure body; a connection to connect the closure body to the housing, thereby defining an operating configuration in which said reciprocal rotation is prevented and a non-operating configuration in which it allows said reciprocal rotation, thus preventing said housing from controlling the passage of the closure body between the closed and open positions; and a data connector to provide wireless data connection with the external apparatus to allow it to control the passage of the connection between operating configuration and non-operating configuration.

A shippable, balanced, self-contained, solar-powered, battery-charging, restricted-access, parkable, equipment station.

A bulk material shipping container unloader having an expandable supporter, a pallet receiver supported by the extendable supporter, a material director supported by the pallet receiver, and a bulk material container gate mover supported by the pallet receiver.
