Key technological points for determining the weight of industrial handcart casters

In industrial production and logistics transportation scenarios, industrial handcarts play an indispensable role, and the weight of their casters directly affects whether the handcart can operate efficiently and safely. The weight of industrial handcart casters is not determined by a single factor, but depends on multiple key technological points.


Material selection and application


The material of the casters is the fundamental factor affecting the weight measurement. Firstly, the material of the wheels is crucial. Common wheel materials include rubber, polyurethane, nylon, and cast iron. Rubber wheels have good elasticity and shock absorption performance, which can to some extent reduce the impact of goods on the trolley. They are suitable for scenarios with lighter loads and higher requirements for ground protection. Polyurethane wheels combine the elasticity of rubber with the wear resistance of plastic, with relatively strong load-bearing capacity, and are commonly used in industrial hand carts with moderate loads. Nylon wheels have excellent wear resistance and can work in high temperature environments, maintaining stable operation while bearing a certain weight. Cast iron wheels have high hardness and strong rigidity, making them an ideal choice for heavy-duty casters that can withstand weights of several tons or even heavier.


In addition to the wheels, the material of the caster bracket cannot be ignored. Generally made of steel, high-quality steel has high strength and good toughness after special treatment. For example, steel treated with hot-dip galvanizing can not only enhance the corrosion resistance of the bracket, but also improve its load-bearing capacity without adding too much weight, ensuring that the bracket will not deform or break under heavy loads.


The subtleties of structural design


Reasonable structural design is the key guarantee for the load-bearing capacity of casters. Firstly, the diameter and width of the wheels. Larger diameter wheels can effectively reduce friction with the ground and rolling resistance when rolling, making it easier to push the handcart when carrying heavy objects. Meanwhile, larger diameter wheels are typically able to withstand greater pressure, thereby increasing the weight capacity of the casters. The increase in wheel width can increase the contact area with the ground, disperse pressure, and further enhance the load-bearing capacity.


The steering structure of the casters also has an impact on the symmetrical weight. For example, a steering system using dual ball bearings can maintain flexible steering performance while withstanding heavy loads compared to ordinary steering structures. This design ensures that the casters are evenly stressed in all directions, avoiding damage caused by excessive local stress, thereby improving the overall load-bearing capacity. In addition, some high-end casters are also equipped with shock absorbers, such as spring shock absorbers or rubber shock pads, which can effectively cushion vibrations on uneven ground, reduce the impact on goods and the casters themselves, and indirectly improve the weight of the casters.


The key role of manufacturing process


Exquisite manufacturing craftsmanship is an important link in ensuring the weight of casters. In the manufacturing process of wheels, high-precision molds and advanced injection molding processes can ensure the dimensional accuracy and quality stability of the wheels. For example, using advanced polyurethane casting technology can evenly fill the mold with polyurethane material, avoiding defects such as bubbles or voids, thereby improving the strength and load-bearing capacity of the wheel.


Strict quality control and precise assembly process are crucial for the assembly process of casters. The precision of the fit between various components directly affects the performance of the casters. For example, if the clearance between the bearing and the shaft is too large, it can cause the casters to shake during operation, reducing their load-bearing capacity; If the fit is too tight, it will increase friction and affect the flexibility of the caster rotation. Therefore, ensuring the assembly quality of each caster through advanced automated assembly equipment and strict testing processes is an important guarantee for improving weighing capacity.


The weight of industrial handcart casters depends on multiple technological factors such as material selection, structural design, and manufacturing processes. Only through continuous technological innovation and optimization in these areas can we manufacture industrial casters with stronger load-bearing capacity and more reliable performance, meeting the growing demands of industrial production and logistics transportation.
