A transportation cart configured to transport video projection screen cases comprises a base frame for supporting a video projection screen case; a plurality of ground engaging units for supporting the base frame from a ground surface; a containment frame located a distance above the base frame and connected thereto; and a first and second strap configured to secure cargo. The transportation cart is also configured to transport a plurality of multipurpose tables and comprises a base; a plurality of ground engaging units for supporting the base from a ground surface; a first and second vertical support extending up from the base.

The invention relates to cleaning cart, comprising a frame having a frame lower part, a frame upper part and support parts which connect the frame lower part to the frame upper part and are spaced apart from one another, rollers at the frame lower part for moving on a ground surface, storage devices for receiving therein and/or supporting thereon cleaning accessories, retaining elements for holding the storage devices, and receiving elements arranged at the support parts in a predefined position, wherein the retaining elements are selectively fixable to the receiving elements for having the storage devices assume different relative positions with respect to the support parts.

A method and a system are disclosed including a stackable storage container. In various embodiments, the stackable storage container includes stacking locks that may be deployed automatically to lock the stackable storage containers together when a first storage container is placed upon the top of a second storage container. A tri-state locking system is used to lock the containers in a stack configuration. Deep chamfers at bottom surfaces and top lids of storage containers allow automatic alignment of the containers. When storage containers are stacked and aligned, a lock status indicator is activated to indicate the state of the stacking locks. The lock status indicator may also have an added function to allow a user to unlock the stacked storage containers to detach and remove them from the stack. The user may not manually lock the storage containers but the user may unlock them manually.

A fixed rod and a pull rod slidingly engageable in the fixed rod with a plug mounted inside the bottom end of the pull rod and a push button mounted at the bottom of the plug. The push button has a first position and a second position with respect to the plug. When the push button is in the first position with respect to the plug, the pull rod is slidable up and down inside the fixed rod. When the push button is located in the second position with respect to the plug, the pull rod is removable from the fixed rod.

A high capacity cargo/container dolly. The cargo/container dolly includes retractable side stops that actively retract a roller linkage assembly upon retraction of the retractable side stops rather than relying on passive gravitational forces for the retraction. In some embodiments, the retractable side stops are configured to avoid hold up on the cargo during retraction. The retractable side stops may be coupled to a retraction mechanism that may be actuated from either side of the cargo/container dolly, as well as from one or both ends of the cargo/container dolly. The dolly may include aspects that accommodates dynamic loads that occur during transport to mitigate inadvertent retraction of the retractable side stops or spurious release of catch assemblies that retains cargo on the dolly. The dolly may also include self-locking roller assemblies that release only in the presence of cargo, and deck modules that protect the deck roller from road spray contamination.

A storage container with various aspects is described herein. The storage container may have cleats or cleat receptacles to interact with other storage containers and/or accessories. The storage container may also include rails for attachment of various accessories. Some versions of the storage container may further include telescopic uprights connected to a handle. Many of the versions of the storage containers may further include wheels for transporting the storage containers and their contents.
