There are many different factors that determine the choice of heavy-duty casters, the key is the most suitable for your use. Here are several ways to choose heavy casters:
1. Carrying capacity
Determine the carrying capacity of a single heavy caster according to the design load. The load-bearing capacity of heavy-duty casters is the most basic and most critical requirement for heavy-duty casters, and the actual conditions of use are very different. Therefore, when choosing the load-bearing capacity of heavy-duty casters, a certain safety margin should be left. The most commonly used Four-wheel installation as an example, usually can be selected according to the following two methods:
Choose according to three heavy-duty casters to bear all the weight. One of the heavy-duty casters is suspended in the air. This method is suitable for occasions where the heavy-duty casters bear high impulse and the ground conditions are poor during cargo shipment or equipment movement, especially when the total weight is large.
Choose 120% of the total weight of the four heavy casters. This method is suitable for occasions where the ground is in good condition and the heavy casters are less impacted during cargo shipment or equipment movement.
It should be particularly pointed out that for those heavy casters that will be subject to a lot of impact, not only should the heavy casters with large load-bearing capacity be selected, but also specially designed impact-resistant structures should be used.
2. Conditions of use of the venue
Choose suitable wheel materials according to the actual working conditions of heavy-duty casters. The wheels are in direct contact with the ground, and they are easily attacked and corroded by various objects on the ground and on the ground and various corrosive media in the surrounding environment. If they are not selected properly, the service life of heavy casters will be greatly shortened, and the working environment will also be affected. The use of wheels has an impact.
Used on rough ground, rubber, polyurethane or super synthetic rubber wheels should be resistant to wear and elasticity; when working under special high or low temperature, or the working environment has a large temperature difference, metal wheels or special-made wheels should be selected High temperature resistant wheels; where it is required to prevent the accumulation of static electricity, it is best to use special anti-static wheels, or metal wheels (if the ground does not require protection); when there are a lot of corrosive media in the working environment, it should be correspondingly Choose wheels with good corrosion resistance.
According to the requirements of the use environment for the adaptability of heavy-duty casters, select the most suitable model.
3. Rotation flexibility
High-precision ball bearings run smoothly and flexibly, especially suitable for high-end equipment and quiet environments; Terling bearings made of high-quality DuPont engineering plastics are widely adapted to various corrosive media; well-made needle roller bearings are still easy under heavy pressure Freely; to protect the beautiful floor, please use soft rubber, polyurethane and super artificial rubber wheels; to avoid leaving unsightly wheel marks on the ground, please choose special gray rubber wheels, polyurethane wheels, super Artificial rubber wheels and other wheels without markings...
4. Temperature requirements
Severe cold and heat may cause trouble for many wheels. It is best to choose wheels that are compatible with the ambient temperature.
5. Other
According to various special requirements, you can choose the appropriate accessories (see the attachment for details). Such as dust caps, sealing rings and anti-wrap caps can keep the rotating parts of heavy casters clean and prevent the entanglement of various fibers, so that heavy casters are still flexible for long-term use; single and double brake devices can effectively prevent heavy The rotation and steering of the casters allows you to stay in any position.
