MODULAR PALLET ASSEMBLY
FIELD OF INVENTION
The present invention relates to a modular pallet assembly, and more particularly to a modular pallet assembly for storing and transporting goods and loads.
BACKGROUND OF INVENTION
Pallet is commonly used in materials handling industry for storing and transporting various type of goods or loads. Pallets can be made from wood, plastic or metal. Wood and plastic pallets are the most widely used pallets in the current materials handling industry. Wood pallets are generally less expensive but these pallets are hard to completely clean especially when they become wet due to leakage from goods or presence of moisture in the environment. This will eventually encourage growth of bacteria and fungus which may lead to safety concerns when use in food, drink and pharmaceutical industries. Besides, wood pallets may also increase the risk of safety hazards to the handlers due to protruding nails or cracks. In addition, wooden pallets also prone to wear and tear and need replacement frequently. This will eventually increase the operating cost. Plastic pallets are easier to clean and more durable compared to that of wooden pallets. However, if the plastic pallet is cracks or broken, the entire pallet will become unfunctional and need to be changed. Although many improvements have been carried out on plastic pallets such as to modularly construct the pallets, most of the existing modular pallets are difficult to assembly, lack of sturdiness and costly due to complexity in moulding and construction.
Therefore, it is desirous to provide a modular pallet assembly which is cost effective, can be assembled easily and also enable replacement to be carried out easily by the handlers when one portion of the pallet is broken.
The modular pallet assembly according to the preferred embodiment of the present invention and its combination of elements or parts thereof will be described and/or exemplified in the detailed description.
