How does the rocker arm of a Li-ion Powered Pallet Truck enhance its strength and structure?

As one of its core components, the rocker arm of a Li-ion Powered Pallet Truck is not only designed to handle the vehicle, but also directly related to operational safety and long-term durability. In order to ensure that the rocker arm can withstand the high-intensity use and complex stress conditions in daily operations, manufacturers have adopted a variety of advanced technologies and design concepts to enhance its strength and structure.
The rocker arm is manufactured by single-piece casting rather than multi-component assembly, which is the key to improving its overall strength and structural continuity. Single-piece casting means that the rocker arm is directly formed from a complete metal block, reducing potential weaknesses and stress concentration points caused by welding or bolting. This process not only improves the overall rigidity and fatigue resistance of the rocker arm, but also simplifies the production process and reduces maintenance costs.
The choice of materials is also crucial. In order to obtain higher strength and toughness, rockers are usually made of lightweight and high-strength materials such as high-strength alloy steel or aluminum alloy. These materials not only have excellent mechanical properties such as high tensile strength, good impact resistance and corrosion resistance, but also reduce the vehicle's own weight while ensuring strength, improving energy efficiency and handling flexibility.
In the design process of the rocker arm, engineers will use advanced computer-aided design (CAD) and finite element analysis (FEA) technology to accurately calculate and simulate the rocker arm's geometry, cross-sectional dimensions, wall thickness distribution, etc. to optimize its structural strength and stress distribution. For example, by increasing the wall thickness of key parts, adopting a reasonable cross-sectional shape (such as an I-shaped or box-shaped section), and optimizing the transition design of the connection parts, the rocker arm's load-bearing capacity and anti-deformation ability can be effectively improved.
In addition to the above basic design principles, the rocker arm may also contain some additional strengthening structures, such as reinforcing ribs, ribs, or internal fillers, which can further enhance its structural strength and stability. In addition, the application of surface treatment technologies such as shot peening, heat treatment, or surface coating can also significantly improve the wear resistance, corrosion resistance, and fatigue life of the rocker arm.
The rocker arm of the Li-ion Powered Pallet Truck has achieved a dual improvement in strength and structure through the use of a single-piece casting process, the selection of high-strength materials, fine optimization design, and the addition of strengthening structures and surface treatment. These measures together ensure that the rocker arm can maintain excellent performance and reliability in complex and changing operating environments, providing a solid guarantee for the safe and efficient operation of the pallet truck.
