Tray selection can be considered from the following aspects:
Tray size: Determine the tray size according to the tray standard and the size of the stored material. It is recommended to use standard trays whenever possible. (At present, there are four standard tray sizes commonly used: 1200mm×1000mm, 1200mm×800mm, 1140mm×1140mm, and 1219mm×1016mm. Enterprises should use these trays as much as possible to facilitate the exchange and reuse of trays.) The size of the pallets is selected primarily with regard to the size of the transport and transport equipment. The appropriate pallet size should be exactly the size of the vehicle, which can improve the full and reasonable use of the space of the vehicle and save the transportation cost, especially considering the container size of the container and the transport truck. Secondly, consider the size of the warehouse and the size of the pallets. Select the pallets of the right size according to the packing specifications of the pallet-loaded goods to maximize the surface area of ​​the pallets. At the same time, the flow of the pallets carrying the goods will directly influence the choice of pallet size. Usually, the goods going to Europe should choose 1200mm×1000mm trays, and the goods going to Japan should choose 1100mm×1100mm trays.
Tray material: According to the use of different environments, choose a different material tray. (packing box quotes)
(1) Temperature conditions: Different use temperatures directly affect the choice of pallet manufacturing materials. This is because trays of different materials have a temperature range in which their performance is normally exerted. For example, the use temperature of plastic trays is between +40 and -25°C.
(2) Moisture: Due to the strong hygroscopicity of some material trays, wood pallets cannot be used in wet environments, otherwise they will directly affect the service life.
(3) Cleanliness of the environment: In environments with high levels of contamination, it is necessary to choose a pallet that is resistant to contamination and easy to clean. Such as plastic trays, composite plastic trays and so on.
(4) Whether to export: Since many countries require fumigation and insecticidal treatment for packaging materials used for imported goods, trays used for export should try to select trays for fumigation-free composite materials.
(5) Load-bearing requirements: Steel pallets are generally used only for the purpose of solving the problem of loading of heavier cargoes. The plastic pallet is an integral structural pallet that is suitable for turnover and is not easily damaged, but its carrying capacity is not as good as wooden pallets. Wooden pallets are rigid and can be used in most logistics operations.
Pallet structure: The pallets have different construction methods, which are selected according to the characteristics of the forklift's forks, bearing requirements and other application conditions. The structure of the tray directly affects the use efficiency of the tray. The proper structure can fully display the characteristics of high-efficiency operation of the forklift. The pallet is used as a floor plank, that is, the pallet is no longer moved after loading the cargo, but only plays the role of moisture-proof and waterproof, and can select a simple structure and a low-cost pallet, such as a simple plastic pallet, but the static load of the pallet should be paid attention to. For pallets used for transportation, handling, and loading and unloading, pallets with high strength and dynamic load are selected. Because this type of tray is used repeatedly and must be used with a forklift, it requires a higher strength of the tray. This requires that the structure of the tray be "Tian" or "Chuan". According to whether or not the pallets are to be stacked after loading the goods, it is decided whether one-sided or two-sided pallets are to be selected. Since a single-sided tray has only one bearing surface and is not suitable for stacking, it is likely to cause damage to the underlying cargo. Therefore, after stacking goods, stacking must be performed, and the trays on both sides must be selected as much as possible. If the tray is used on a shelf in a three-dimensional library, consider whether the structure of the tray is suitable for placement on the shelf. Since the goods can only be picked up from the shelves in two directions, the trays used on the shelves should use trays that are four-pronged as far as possible. This facilitates the forklift to pick up the goods and improves work efficiency. Such trays generally select the structure of the field line. (Packing box)
Cost: Wooden pallets cost low, but China currently does not have pallet standards. Wooden pallets of the same structure vary in quality due to differences in the materials used or processing techniques. Market prices vary widely and range from $50 to $300. Wooden pallets can be damaged if they are not properly managed, but they can be repaired. Due to rising oil prices, the cost of plastic pallets is much higher than wood pallets. Plastic trays have a longer service life than wooden pallets, but they cannot be repaired after they have been damaged.
The Homecare Bed is a Hospital Bed specially designed for patients with inconvenient mobility to use in home care. Its main purpose is to facilitate nursing care by nursing staff and facilitate patient recovery.
Homecare beds can be divided into manual homecare beds and electric homecare beds according to the operation mode.
Our manual nursing beds can be clearly divided into single crank manual bed, two cranks manual beds and three cranks manual beds, according to the number of hand cranks.
Our manual homecare beds are also supplied with integrated split side rails as a standard feature to assist with sit-to-stand procedures & enhance patient safety.
