Description

Technical Field

[0001] This utility model relates to the field of pallet technology, specifically a lightweight quick-release guardrail. Background Technology

[0002] Fully loaded pallets are one of the main carriers for containerized transportation. The basic idea is to first load the goods onto unit flat pallets, and then use a forklift to place the loaded flat pallets onto fully loaded pallets.

[0003] The main problem with existing full load and unload pallets is that they lack baffles around their sides, preventing bulk goods such as boxed, barrelled, or bagged goods from being directly loaded onto them. Without forklifts or other mechanical equipment, it is impossible to complete the loading and transportation of bulk goods.

[0004] Therefore, it is necessary to develop a lightweight guardrail that can be installed on the loading and unloading pallet without making any changes to it. Utility Model Content
