A rack system movable by a forklift having blades that can be selectively raised and lowered. The rack system includes a rack and a hitch device for connecting the forklift to the rack. The rack includes a structure configured for supporting and transporting materials, at least one wheel located at a first end of the structure, and a hitch bracket located at a second end of the structure. The hitch device includes a body configured to be carried by the blades of the forklift, and an arm pivotably secured to the body, and an engagement member at the second end of the arm. Upward movement of the blades raises the engagement member into engagement with the hitch bracket so that further upward movement of the blades raises the second end of the rack and horizontal movement of the forklift rolls the rack on the at least one wheel.

A photovoltaic module packing box and a photovoltaic module package structure are provided. The photovoltaic module packing box includes a tray having an accommodation space; a support plate having an edge hinged to an edge of the tray, and the support plate is lapped on the tray; an airbag assembly arranged in the accommodation space; an air valve assembly connected to the airbag assembly by a pipeline; an enclosure frame connected to the support plate and configured to enclose, together with the support plate, a receiving space for photovoltaic modules, and the enclosure frame includes a fixation part and a movable part; the fixation part is fixed to the support plate with one side thereof configured as an open structure; the movable part is detachably connected to the open structure of the fixation part, and the movable part and the fixation part together form an annular structure.

Shipping containers for covers or baseplates of reticle pods include a first shell including first fixing features and a second shell including second fixing features. When the first shell and the second shell are joined, the shells define an internal space capable of accommodating a cover or a baseplate of a reticle pod, and the fixing features engage the cover or baseplate to prevent movement of the cover or baseplate in directions in plane with the first or second shells. The fixing features can be such that there are both rigid and elastic fixing features contacting the cover or baseplate. A method of storing a cover or baseplate can include placing the cover or baseplate between first and second shells and joining the first and second shells to one another.

A shipping system for shipping planar substrates includes a plurality of planar substrates stacked to form a pack and a plurality of interleaving material including substantially spherical beads positioned between the substrates of the pack and configured to carry a load. Substantially all of the beads have a diameter within 25% of D.sub.max, where D.sub.max is a diameter corresponding to a size of an opening of an upper limit sieve used in the shipping system. Also disclosed are a spacer for use in a shipping system for shipping planar substrates, a wrapped system for shipping planar substrates, a method of wrapping a system for shipping planar substrates, and a powder applicator.
