Definition: Heavy-duty casters are classified according to their load-bearing capacity, and have a greater load capacity than light-duty casters and medium-duty casters.
Classification: There is no clear boundary for heavy-duty casters, but generally casters with a load capacity of 500 kg to 15 tons or even higher are called heavy-duty casters. Some materials also mention that the load capacity of heavy-duty casters can range from 155 kg to 7530 kg.
2. Structure and Features
Bracket design: The bracket of heavy-duty casters usually uses metal materials as the main body, such as ordinary steel plate stamping, cast steel molding, die-forged steel molding, etc. These bracket designs are sturdy and durable and can carry a large weight. At the same time, the steel plate thickness of heavy-duty casters is also large, and the common specifications are 8mm, 10mm, 16mm and more than 20mm. Some extra-heavy casters even use 30mm thick steel plates.
Swivel plate design: Heavy-duty casters usually adopt a double-layer steel ball runway design and are heat-treated to enhance their durability. For extra-heavy universal wheels, flat ball bearings or flat needle bearings with greater force will be used, and tapered bearings will be used to improve their load capacity.
Wheel material: Heavy-duty casters generally use hard tread single wheels, such as nylon wheels, cast iron wheels, forged steel wheels, hard rubber wheels, polyurethane wheels, and phenolic resin wheels. These materials have good wear resistance and load-bearing capacity, and can meet the needs of different application scenarios.
Wheel diameter: The larger the wheel diameter of the heavy-duty caster, the more flexible the rotation. Common specifications include 4 inches, 5 inches, 6 inches, 8 inches, 10 inches, 12 inches, etc., and extra-heavy casters can even use 16-inch and 18-inch wheels. In addition, special specifications of heavy-duty casters can also be customized, such as low-center-of-gravity heavy-duty casters.
3. Application scenarios
Industrial production lines: Heavy-duty casters support the flexible movement of heavy equipment such as large machine tools, production line equipment, and robots, improving production efficiency.
Logistics warehousing: They are standard equipment for logistics equipment such as forklifts, stackers, and trolleys, ensuring the rapid and safe transfer of goods.
Medical field: It is used in mobile operating tables, X-ray machines and other medical equipment, providing convenient operating space for medical staff.
Scientific research field: The frequent movement and positioning of experimental equipment also cannot be separated from the support of this type of high-performance casters.
