1. Carrying capacity
The load capacity achieved by a single heavy caster is determined by the design load capacity. The load-bearing capacity of heavy-duty casters is the basic and key requirement of Z-type heavy-duty casters. The actual use conditions vary greatly, so when actually selecting the load-bearing capacity of heavy-duty casters, a certain safety margin should be reserved. Taking the most commonly used four-wheel installation as an example, you can generally choose the following two methods: Choose three heavy casters to bear all the weight. One of the heavy casters is suspension type, this method is suitable for the movement of loaded goods or equipment, the heavy casters bear large impact, and the ground conditions are poor, especially when the total weight is large.
Choose according to 120% of the total weight of the four heavy-duty casters. This method is suitable for occasions where the ground conditions are good and the impact of heavy casters is small during cargo shipment or equipment movement.
Second, the use of site conditions
Choose a suitable wheel material according to the actual management working and living conditions of heavy casters. The wheels are in direct contact with the ground, and are easily attacked and corroded by various corrosive media on the ground and on the ground and in the surrounding social environment. If we choose an improper method, the service life of heavy-duty casters will be greatly shortened, work and study The environment will also have a certain impact on the use of wheels.
3. Rotation flexibility
High-precision ball bearings are particularly smooth and flexible, especially suitable for high-quality equipment and quiet environments; high-quality DuPont engineering plastics manufacturing spirit bearings are widely adaptable to various corrosive media; delicate needle bearings are still easy under heavy pressure; use soft rubber, polyurethane rubber and super Elastomeric wheels; To avoid leaving unsightly rut marks on the ground, choose special gray rubber wheels, polyurethane wheels, super elastomeric and other stainless steel wheels.
4. Temperature requirements
Severe cold and heat will cause failures to many wheels, and it is most suitable for the selection of the ambient temperature of the wheels.
5. Others
According to various special requirements, you can choose suitable accessories (see accessories for details). Such as dust cover, sealing ring, and anti-winding cover, which can keep the rotating parts of heavy casters clean and prevent various fiber entanglements, making heavy casters as flexible as before in long-term use. Single and double braking devices can effectively block heavy casters The turning and steering allows you to stay in any position.
