Abstract
A pallet includes a deck and one or more leg-plank bridges that extend from the deck. The leg-plank bridges include one or more legs and a plank that extends between the legs. The legs and plank are integrally formed together and attached to the deck. The legs have one or more internal walls that define one or more cavities. Concrete fills the cavities of the legs located on a lead end of the pallet. The remaining cavities in the legs are filled with foam. The cavities in one version are wedge shaped. Other legs of the deck are filled entirely with foam.
Claims19
A pallet, comprising:
- a deck;
- at least two legs extending from the deck;
- a plank coupled to the legs;
- wherein the plank extends in a longitudinal direction between opposing lead sides of the pallet;
- wherein the legs and the deck at least in part define a fork opening at one of the lead sides of the pallet;
- wherein the fork opening is configured to receive a fork that extends in the longitudinal direction when inside the fork opening;
- wherein each of the legs has one or more walls that define at least two cavities within the leg;
- wherein the cavities include a lead side cavity and an interior side cavity;
- wherein the lead side cavity is positioned at the lead side of the pallet;
- wherein the interior side cavity is positioned opposite the lead side cavity;
- concrete filling the lead side cavity to strengthen the leg against impacts by the fork;
- a foam insert made of foam extending within the interior side cavity, wherein the foam insert include a base, a stem extending from the base, and one or more petals extending around the stem;
- and
- wherein the lead side cavity is empty of the foam insert.
