Description

Technical Field

[0001] This utility model relates to the field of logistics pallet technology, specifically to a lightweight heavy-duty pallet. Background Technology

[0002] With the rapid development of the logistics industry, pallets, as an indispensable load-bearing tool in logistics transportation, are constantly being improved in design and manufacturing technology. Traditional pallets are mostly made of wood, which, although low in cost, has many shortcomings in terms of strength, durability, and environmental friendliness. In recent years, metal pallets have gradually become the mainstream choice in the market due to their advantages such as high strength, corrosion resistance, and recyclability. However, the weight of metal pallets increases transportation costs and limits their application in certain fields. Therefore, developing a lightweight metal pallet has become a current research focus. Utility Model Content

[0003] The present invention aims to provide a lightweight heavy-duty pallet to solve the logistics problems of existing pallets, such as large loading space occupation, large weight, and high cost of heavy-duty export.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A lightweight heavy-duty pallet includes a pallet body, which is symmetrically trapezoidal in shape. The pallet body includes long beams, diagonal beams, top tubes, forks, and square tubes. The long beams are elongated and are welded beam profiles. The long beams are evenly and parallelly arranged, and forklift square holes are provided on the long beams. U-shaped bends are welded to the forks. The two ends of the long beams are connected by welded diagonal beams to form the main pallet frame. The U-shaped bends of the top tubes are evenly spaced and laid flat on the long beams. An additional square tube is laid above the forks for reinforcement.

[0006] The principle and advantages of this solution are as follows: In practical applications, the pallet body is designed as a symmetrical trapezoidal shape, which facilitates the use of the pallet without breaking it. The long beam is designed as a welded beam profile (also called a rack profile) with a wall thickness of only 1.5mm and a hollow center, which helps to reduce the weight of the pallet while maintaining a strong load-bearing capacity. Fork openings are made on the long beam to facilitate forklifts to fix and transport the pallet. The fork openings are welded with U-shaped bends to strengthen and protect the stress points of the pallet, reducing stress deformation of the pallet during load-bearing. The surface tubes are evenly spaced and laid flat on the long beam, and square tubes are laid in the space above the fork openings for reinforcement, which helps to meet the load-bearing requirements while reducing material and further improving the load-bearing capacity of the pallet.

[0007] Preferably, as an improvement, the acute angle of the symmetrical trapezoidal shape is 45 degrees.

[0008] Technical benefits: Facilitates the assembly and use of pallets.

[0009] Preferably, as an improvement, the number of long beams is not less than three.

[0010] Technical benefits: It helps reduce the deformation of the pallet under heavy loads.

[0011] Preferably, as an improvement, the long beam has a specification of 140*50*1.5mm.

[0012] Technical benefits: Lightweight and high load-bearing capacity.

[0013] Preferably, as an improvement, the square tube is made of Q235 steel.

[0014] Technical benefits: Improves load-bearing capacity and reduces deformation during forklift transport.

[0015] Preferably, as an improvement, the long beam, the face tube, and the square tube undergo post-weld grinding and sharpening treatment after welding.

[0016] Technical benefits: The tray is free of sharp corners and burrs, with a smoother surface, preventing damage to the transported items.

[0017] Preferably, as an improvement, the tray body is painted yellow.

[0018] Technical benefits: Facilitates unified management of pallets while protecting the pallet surface and preventing oxidation. Attached Figure Description

[0019] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0020] The following detailed description illustrates the specific implementation method:

[0021] The reference numerals in the accompanying drawings include: 1. Surface tube, 2. Inclined beam, 3. Square tube, 4. Fork, 5. Long beam.

[0022] The basic implementation examples are as follows: Figure 1 As shown:

[0023] A lightweight heavy-duty pallet includes a pallet body, which is symmetrical trapezoidal in shape with an acute angle of 45 degrees to facilitate the splicing and use of the pallet. The pallet body includes a long beam 5, a diagonal beam 2, a top tube 1, a fork joint 4, and a square tube 3.

[0024] The long beam 5 is elongated, with its ends cut at a 45-degree angle to form a regular trapezoidal shape, reducing sharp edges and avoiding safety hazards. There are at least three long beams 5 to minimize pallet deformation under heavy loads. The long beam 5 is a welded beam profile with dimensions of 140*50*1.5mm. The long beams 5 are arranged evenly and parallel, specifically with their wider sides aligned and their thinner sides contacting the face tube 1. The long beams 5 are welded to the face tube 1, thus reducing welding workload. Furthermore, with the same material usage, the load-bearing surface of the long beam 5 is thicker, resulting in stronger pressure resistance. Thirdly, it facilitates the creation of appropriately sized forks 4 on the long beam 5.

[0025] The fork 4 is welded with a U-shaped bend, which facilitates accurate forklift handling and protects the stress points of the pallet, reducing damage to the pallet during load-bearing. The two ends of the long beam 5 are welded with inclined beams 2 to form the main pallet frame. The U-shaped bends of the face tube 1 are evenly spaced on the long beam 5. An additional square tube 3 is laid in the space above the fork 4 for reinforcement. The square tube 3 is made of Q235 steel. The face tube 1 is welded to the long beam 5. The additional square tube 3 in the space above the fork 4 is to improve the pallet's load-bearing capacity.

[0026] After welding, the long beam 5, the top tube 1, and the square tube 3 require post-weld grinding and sharpening treatment to ensure the pallet is free of sharp corners and burrs, resulting in a smoother surface and preventing damage to the transported items. The main body of the pallet is painted yellow for easy and uniform management, while also protecting the pallet surface from oxidation.

[0027] Example 2

[0028] The U-shaped bend is longer than the face tube 1, which facilitates the horizontal setting of a lifting port on the exposed part of the U-shaped bend. This lifting port facilitates the pallet's use during lifting, enabling integrated forklift and lifting applications. In this embodiment, the overall levelness deviation of the pallet is 0-5mm, and the positioning strips are painted with the logo, pallet specifications, and model number.
