Abstract
Abstract A fork pallet structure and a method of manufacturing a forklift pallet which is applicable to handling goods in industries where hygiene requirements are strict, such as food industries, the pharmaceutical and cosmetics industries, and "clean" technology industries. The pallet of the invention comprises a platform (30) and blocks (33-35) for spacing the platform from a rest surface such as the ground, both the platform and the blocks being made of solid plastics material. The blocks are optionally interconnected by a belt or by runners and are connected together by a polyfusion method that does not leave any interstices, and does not run any risk of creating crannies while the pallet is in use. The pallet is suitable for use in industries having strict hygiene requirements, such as the food industry.
