The dimensions of manual two-wheeled hand trucks are typically designed to accommodate a diverse range of hauling requirements. Standard models usually feature a cargo box measuring 1000 x 560 x 350 mm, making them suitable for everyday household tasks or light commercial use. The pull handle is frequently constructed from φ32 x 2.75 mm square tubing-a material also used for the support legs-to ensure structural stability. Wheels generally have a diameter of 650 mm and are available with either pneumatic or solid tires; select models offer 6-inch or 14-inch rubber wheel options featuring anti-slip treads to enhance durability. Both the frame and cargo box typically undergo a baked-paint finish, and some models offer customization options for slogans and logos.
Load-bearing capacity is closely correlated with the hand truck's dimensions and structural design. Lightweight, compact models (e.g., those with smaller cargo boxes) typically support a load of up to 200 *jin* (approx. 100 catties), making them ideal for light-duty hauling. The new generation of reinforced, upgraded models-such as those featuring thickened steel plates or triangular support structures-can bear loads of up to 1300 *jin* (approx. 650 kg), making them suitable for transporting heavy objects. High-capacity models often incorporate reinforced structural elements-such as thicker, heavier support legs and cargo box frames constructed from 44 x 2.3 mm angle iron-and feature correspondingly larger dimensions (e.g., cargo box walls thickened to over 1.5 mm). The relationship between load capacity and size is evident in the fact that larger, more robustly constructed models offer greater load-bearing strength, though this may come at the expense of portability.
When making a purchase, it is essential to select a size that aligns with your specific usage scenarios and requirements. For daily household use (e.g., grocery shopping or moving small items), a lightweight model with a smaller footprint (e.g., a cargo box length of around 1000 mm) and a load capacity of 200–300 *jin* is recommended, as it facilitates easy storage and maneuverability. For commercial or industrial settings (e.g., warehouse inventory transport or construction site material handling), a reinforced model with larger dimensions (e.g., a cargo box length exceeding 1100 mm) and a load capacity of 600–1300 *jin* is advisable to ensure both durability and operational efficiency. For elderly users or individuals with limited physical strength, priority should be given to models of moderate size that feature adjustable handle heights and ergonomic designs to minimize physical exertion (e.g., models equipped with silent-operation wheels or non-slip handles), thereby avoiding the operational difficulties that can arise from using oversized equipment.
