Assembly type steel pallets

More particularly, the present invention relates to a steel pallet for use in production and storage of products and transportation of goods, and more particularly, to a pallet which can be assembled and separated easily with a simple structure, The present invention relates to a prefabricated steel pallet that can simplify the elements and lighten the weight and improve the bearing capacity through various reinforced structures.

Generally, a pallet disposed at the lower part of a bundle bundle for facilitating the transportation of forklifts is made of wood, synthetic resin, etc., and has been widely used for transportation of cargoes at most factories or quays.

However, the conventional pallet described above has a problem in that the volume of the empty pallet itself except for the cargo is formed to be too large, which makes the volume of the cargo unnecessarily unnecessarily large, resulting in an excessive cost of logistics.

In addition, the pallet of wood material can be produced various kinds of germs, which is unsafe for hygiene, and a pallet made of plastic or synthetic resin that can replace it is advantageous in that the production cost is low. However, So that it is practically impossible to produce pallets of various sizes.

In recent years, in order to compensate for this problem, conventional steel pallets have been produced, but the number of parts has increased, resulting in problems such as an increase in production costs and difficulty in automating mass production, and the assembled piece bolts are easily relaxed due to vibration during prolonged use And the shortage of the service life of the pallet has shortened.
