Warehouse Automation: Improvements for the Precise Placement of Irregular Pallets
… The new warehouse’s job is to autonomously move pallets, also known as “units,” of stacked green lumber through the warehouse and onto the dry kilns. However, avoiding large gaps after placing the units on the drying kiln’s carts has proven to be more difficult than anticipated. This work dives …

Load-support conditions and computerized test apparatus for wood pallets
The in-service loads on wood pallets are often uniformly distributed in nature. Laboratory test methods to evaluate pallets typically use point or line loads because of the difficulty of simulating the actions of a uniform load. In support of research directed at developing design procedures for …

Finite Element Modeling of Plastic Pails when Interacting with Wooden Pallets
… The relationship between corrugated boxes and pallets have been previously investigated and have found that the relationship can be used to reduce the quantity of material used in unit loads and can also reduce the cost per unit load if the package and pallet are designed using a systems …
