Castor mainly in such aspects as trolleys, mobile scaffolding, workshop trucks are widely used, in the process of guarantee normal movement function, in addition to considering its own structure, bearing capacity, such as speed also have certain requirements for industrial casters. Here, the grain of castor is to do a simple introduce for everybody. When using castor, wants to anticipate its use, the function, use conditions ( Using range) , and then choose the appropriate type. Need to pay attention to the following: first proper bearing load, product introduction may be bearing load refers to the use manual operation in a flat on the ground is easy to move in the general bearing, at the same time is able to work for a long time in the state of security for such handling general load, the need to estimate the total weight of carrying objects beforehand, and then press allowed by the weight to choose the appropriate castor. Usually occurs in only three of the four castor stress situation, only using a mixture of different sizes of castor, please what kind of castor with a low bearing load as a benchmark, to calculate the overall big bearing weight. About speed, the requirement of caster wheel speed is: under normal temperature environment, is not higher than walking pace, in a flat on the ground, have the general use of stop working state. Castor wheel diameter of 75 mm below the following 2 km/h, below 100 mm below 4 km/h. According to the specific installation castor instruments, determine the castor wheel diameter, material, installation, Such as the plate mounted, and screw stationary, etc. ) And the use of castor type ( Such as flexible rotation type, fixed type, can be stopped, etc. ) 。 In short according to the existing castor varieties or optional various types, weighed and then choose suitable industrial casters. There is no good, only appropriate, grain to advice the user to combine their own actual situation, several more. Grain of Suggestions, user before buying castor, need to know about some knowledge on the caster, so as to give play to the role of castor exaggerated.
