A modular pallet formed from a plurality of frame members and a plurality of deck members. The deck members extend between the frame members to define an upper deck surface and optionally a lower deck surface of the pallet. A plurality of spaced-apart channels are formed in at least an upper surface of the frame members to receive the deck members. In some embodiments the pallet may be configured as a stringer pallet and in other embodiments the pallet may be configured as a block pallet. In some embodiments the frame members are unitary stringers. In other embodiments the frame members are modular structures each comprising a block pallet subassembly and a deck support panel. The number, size, orientation and spacing of the channels formed in the frame members and the corresponding arrangement of the deck members may vary in different embodiments of the pallet. Once assembled, the frame members and deck members may be integrally connected, such as by heat welding. In some embodiments the pallet is formed from readily recyclable plastic.

A cart and rack assembly for transporting a planar material includes a rack and a cart. The rack includes a frame coupled to a base. The frame has an upper portion and a lower portion. The upper portion has a first width, and the lower portion has a second width. The cart is configured to reversibly receive the base. The cart includes a guide member configured to guide either of the base or the cart into a predetermined position when the base is received by the cart. The assembly further includes a bracket having a first end and a second end which is configured to selectively secure the planar material to the assembly. The base has a series of apertures configured to accept the first end of the bracket. The second end of the bracket is configured to be selectively coupled with the upper portion of the frame.

An adjustable all-terrain dolly system (100) having a chassis assembly (110) that includes a frame (120) which has a right-side rail (122), a left-side rail (124), a first-adjustable cross member (126) and a second-adjustable cross member (128), and a first-rolling assembly (160) to include a first-set of inline wheels (164) and a second-rolling assembly to include a second-set of inline wheels (174 and at least one adjustable-locking mechanism (180). The frame of the dolly system defines a load-supporting platform, and the platform has a length which is at least about twice the front-to-rear length of each of the two sets of wheels. Furthermore, each wheel of the dolly system has a peripheral surface which is shaped to engage the underlying surface at a substantially single point to enhance the maneuverability of the dolly.

A cart and rack assembly for transporting a planar material includes a rack and a cart. The rack includes a frame coupled to a base. The frame has an upper portion and a lower portion. The upper portion has a first width, and the lower portion has a second width. The cart is configured to reversibly receive the base. The cart includes a guide member configured to guide either of the base or the cart into a predetermined position when the base is received by the cart. The assembly further includes a bracket having a first end and a second end which is configured to selectively secure the planar material to the assembly. The base has a series of apertures configured to accept the first end of the bracket. The second end of the bracket is configured to be selectively coupled with the upper portion of the frame.

A pallet comprising at least three upper carrier plates (3) and at least three carrier supports (5), in which the bottom of each upper carrier plate (3) is provided with first snapping portions (11) in an array manner, the top of each carrier support (5) is provided with first snapping grooves (4), and the upper carrier plates (3) are snapped with the first snapping grooves (4) on the top of the carrier supports (5) through the first snapping portions (11), and which reduces space occupation and facilitates storage and transportation.

A system and method can change location pins on a pallet for an assembly line. The system may include a plurality of pallets, each pallet including at least a first and second sockets configured to receive a location pin. The system may include a pin changing unit located between a top assembly line and a lower return line. The pin changing unit may include a pin grabber configured to engage the location pin within the first socket. The pin changing unit may include a horizontal linear actuator configured to move the pin grabber and the engaged location pin into alignment with the second socket. The pin changing unit may include a vertical linear actuator configured to extend the pin grabber into engagement with the location pin and retract the pin grabber away from the location pin.

In one embodiment, a maintainable pallet is provided with interchangeable support structures and sensors for identifying any damage that the interchangeable support structures may experience. The maintainable pallet may include two side supports, two end supports coupled to the two side supports end-to-end to form a rectangle, a central support position between the two side supports, a plurality of top transverse support fastened onto the two side supports to form a top loading surface and the central support with two-part releasable fasteners, and two bottom transverse supports fastened to the ends of the two side supports to form a bottom surface with two-part releasable fasteners. Sensors, in some embodiments, may be embedded in the two side supports to measure, for example, acceleration, location, or other logistic information. When a damaged piece is identified, the maintainable pallet can be disassembled by unfastening the two-part releasable fasteners to remove the damaged piece; and a new interchangeable piece will replace the damaged piece.

The present invention provides a system for stacking, storing, and loading metal sheets. In accordance with a preferred embodiment, the present invention provides a pallet which includes multiple posts that allow alignment of sheets of material on the pallet. Preferably, the pallet further includes posts which include stacking bells which allow the pallets to stack together while preventing damage to loaded materials. In accordance with one preferred embodiment of the present invention, the pallets may be stored in a specially designed rack.

An assembly type pallet, includes a plurality of plates having a secure hole on a plate surface, and disposed side by side to each another; a plurality of support frames disposed in a direction intersecting the plates, an inside of the support frame being provided with an inner space along a longitudinal direction, an upper surface of the support frame being provided with a seating surface against which a lower surface of the plates is supported, and the seating surface being provided with an insertion hole communicating with the inner space; a first secure member disposed on the lower surface of the plates and that is provided with an insertion unit which is inserted into the insertion hole of the support frame; and a second secure member inserted into the inner space of the support frame.

The present disclosure relates to roofing shingles and palleted pluralities thereof that have a reduced susceptibility to damage during shipment.
