How can all-iron trays be designed to achieve more stable load-bearing capacity for goods of different shapes and sizes?
Release Time : 2026-03-25
In the logistics and warehousing field, all-iron trays, with their high strength, durability, and environmental adaptability, have become core equipment for the transportation and storage of heavy goods. For goods of different shapes and sizes, all-iron trays need to achieve stable load-bearing capacity through structural optimization. Their design logic encompasses mechanical principles, material properties, and scenario adaptability. The following analysis focuses on four dimensions: key structural design, forklift entry method selection, modular expansion, and surface treatment.
1. Key Structural Reinforcement: Pressure Dispersion and Deformation Resistance Design
The load-bearing stability of all-iron trays primarily relies on the mechanical optimization of their core structure. Taking a 19-fold panel developed by a Nanjing company as an example, by increasing the number of folds to 19, the panel's load-bearing capacity is increased by 30%-50% compared to the traditional 13-fold design. This multi-fold structure extends the force transmission path, evenly distributing the pressure of the goods to the edge of the tray, avoiding deformation caused by localized stress concentration. For example, when carrying heavy goods such as car engines, the 19-fold edge panel can withstand a dynamic load of up to 4 tons, far exceeding the standard 2-ton capacity of ordinary pallets.
2. Forklift Entry Adaptability: Flexible Selection of Two-Way and Four-Way Entry
The forklift entry method directly affects the stability of the pallet during handling. Two-way entry pallets have forks at only two ends, suitable for light goods or space-constrained scenarios, such as transporting bagged raw materials in food processing plants. They have a simple structure and low cost, but limited operational flexibility. Four-way entry pallets, through the cross-shaped layout of the bottom beams, allow forklifts to enter from any direction, significantly improving loading and unloading efficiency. For example, in automotive manufacturing workshops, four-way entry pallets can be used with automated handling robots to achieve rapid turnover of heavy vehicle body parts, while reducing the risk of goods tilting through evenly distributed stress points.
3. Modular Expansion: Customizable Design to Meet Diverse Needs
For irregularly shaped goods, modular design becomes a key solution. By adding accessories such as anti-slip strips, guardrails, and stacking holes, pallets can adapt to the fixing requirements of goods of different shapes. For example, in agriculture, when transporting bagged grain, removable guardrails are added to the edges of pallets to prevent goods from slipping. In the machinery manufacturing industry, positioning holes are made on the pallet surface, and heavy parts are secured with bolts to prevent displacement during transportation. Furthermore, the modular design allows for flexible adjustment of pallet dimensions. For example, to accommodate 40-foot containers, extra-long pallets of 1200×2400mm can be customized, with increased beam density ensuring load-bearing stability.
4. Surface Treatment Optimization: Dual Protection Against Rust and Slip
The surface treatment of all-iron trays directly affects their service life and cargo safety. Hot-dip galvanizing forms a 0.05-0.1mm zinc layer on the pallet surface, effectively resisting humid and corrosive environments, suitable for chemical plants, cold storage facilities, and other similar environments. For example, in chemical warehouses in coastal areas, hot-dip galvanized pallets can withstand salt spray corrosion and have a service life of over 10 years. Electrostatic powder coating, by covering the surface with an environmentally friendly coating, improves rust resistance while increasing the coefficient of friction to prevent cargo slippage. For example, in the transportation of electronic components, powder-coated pallets can prevent damage to precision parts caused by slippage.
