A rack for a heavy equipment bucket having a rectangular base and two vertical posts. Each vertical post has one or more upwardly angled extending protrusions. A series of double ended reverse hooks are provided with the rack for stacking heavy equipment buckets.

A stackable bucket having a floor, a back wall, and two side walls has a tapered front to back floor but wherein the back wall is substantially rectangular. A diagonal bend allows each side plate to connect to the tapered floor and to the rectangular back wall. Gussets and double-ended reverse hooks may also be used to provide spacing between nested buckets.

A safety article, including: a stackable hollow first article stackable with one or more other first articles having substantially the same dimensions, and a second article positioned inside and attached to the interior of the stackable hollow first article, wherein the second article tolerates stacking of two or more of the safety articles, and the second article prevents jamming together or sticking together of the two or more stacked safety articles by preventing the first articles from fully nesting.

Assemblies, systems, and methods for stacking, destacking, or stacking and destacking a plurality of trays that includes a conveyor having a first rail and a second rail; a lift subassembly configured to stack or destack a plurality of trays having predetermined dimensions, the lift subassembly comprising a first set of arms slidably coupled to a lift plate; a second set of arms slidably coupled to the lift plate; and a bracket configured to slidably couple the lift subassembly to the first rail and the second rail, wherein the first rail, the second rail, or the first and second rails are adjustable along the bracket of the lift subassembly to correspond to the predetermined dimensions of the plurality of trays, and wherein each of the first and second sets of arms are independently adjustable to correspond to the predetermined dimensions of the plurality of trays.

A road cone deployment and collection system comprising including a chute having an upper road cone holding section and a rear opening at the bottom of the chute for road cone deployment and a front opening at the bottom of the chute for road cone collection. A road cone retention and release mechanism is configured to hold a stack of road cones, separate and release one road cone at a time from the stack to the chute for deployment from the rear opening, and add a road cone to a stack of road cones collected from the front opening of the chute and raised to be added to a stack of road cones.

A taco stacking apparatus comprises a conveyor assembly for supporting and moving taco shells along a predefined pathway. The conveyor assembly defines an opening in the predefined pathway that enables the taco shells to pass through the conveyor assembly. A stacking receptacle defines a channel for receiving taco shells passed through the opening in the predefined pathway of the conveyor assembly. A plunger assembly passes a taco shell through the opening in the predefined pathway of the conveyor assembly to the stacking receptacle.

A pallet stacker according to an example embodiment includes a corral defining an interior storage space configured to retain a stack of pallets. At least one lifting mechanism is configured to engage a bottom pallet of the stack of pallets, to lift the stack of pallets to permit insertion of at least one new pallet below the stack of pallets, and to lower the stack of pallets onto the new pallet.
