A modular rack for mounting components of a phytochemical extraction system is described. The module rack includes at least two legs and one or more frame modules that are each at least 2 units in length. Multiple frame modules can be combined to create racks of width N, where N is an integer greater than 2 units in length. Each frame module may also include mounting devices configured to removably attach extraction columns to the frame module.

A track system configured for use with a storage rack assembly is provided. The track system comprises first and second forward wheel assemblies, first and second rearward wheel assemblies and a forward axle assembly. The forward axle assembly is coupled between the first and second forward wheel assemblies in an operating position. The forward axle assembly comprises a first intermediate member, a first forward axle member and a second forward axle member. The first forward axle member has a first end coupled to the first forward wheel assembly and a second end slidably coupled to the first intermediate member. The second forward axle member has a first end coupled to the second forward wheel assembly and a second end slidably coupled to the first intermediate member. The first intermediate member inhibits rotation of the first and second forward axle members along their respective axes.

A storage system includes a framing assembly, a plurality of storage units, and a sliding wall assembly. The framing assembly includes a plurality of side panels and a plurality of rear panels. Each storage unit includes a top surface and a base surface, each of the top surface and the base surface secured to and spanning a pair of side panels and the associated rear panel. The sliding wall assembly includes a sliding wall and upper and lower track systems. The sliding wall moves laterally parallel to the plurality of side panels. Each track system includes a panel track member and a wall track member, wherein the panel track member is secured to a side panel and the wall track member is secured to the upper or lower surface of the sliding wall.

Variable planform shelving systems include a variable support platform and a support surface assembly that is supported by the variable support platform. The variable support platform includes frames that can be repositioned relative to each other to vary the planform of the variable support platform. The support surface assembly provides a support surface for supported items. The support surface assembly is flexible and/or comprised of a plurality of linked panels so that the support surface provided varies in response to variation in the planform of the variable support platform.

A delivery vehicle has separate compartments with a common sidewall. Doors that are interchangeable between the compartments close the compartments. A latching assembly between the doors and sidewall limits movement of the sidewall when only one of the doors is closed. The compartments are combined into a single compartment by moving the sidewall when the doors are open. A hinge assembly connects the doors. A contact and wiper assembly between the doors carries power and commands for the hinge assembly.
