Castor plant is how to choose the heavy-duty casters heavy-duty casters products stent design major is usually adopts metal material as the main body, including ordinary steel plate stamping molding, cast steel, forging steel forming, etc. , this often is given priority to with flat plate assembly. Mainly for heavy duty caster steel plate thickness 8 mm, commonly used 10 mm, 16 mm and more than 20 mm steel plate. Wanda now for China petroleum system design of bearing 12 tons of track, castor, mainly USES is 30 mm thick steel plate by 40 mm, the effective guarantee the safety of loading products. Heavy duty castor wheels material choice of heavy duty castor is used for the movement of the heavy equipment, so the heavy duty castor wheels generally adopts hard single wheel tread. Wheel, such as nylon wheel, cast iron forging steel wheel, hard rubber wheel, pu wheel, wheel and phenolic resin is the ideal choice. Of forged steel wheel and pu castor wheels especially for track, castor wheels. Heavy duty castor wheels choice according to the diameter of the wheel diameter, the greater the rotation of the more flexible principle of commonly used specifications are 4 inches castor, castor 5 inches and 6 inches castor, 8 inches castor, 10 inches castor, 12 inches castor, track, caster can use 16 inches and 18 inches of the wheel. At present, we produce 12 tonnes of track, castor, is to use the 400 mm diameter, width of 125 mm of the caster. Heavy, of course, can also be customized special specifications, for example, low center of gravity heavy-duty casters, minimum 2 inches castor, can also be bearing more than 360 kg. The choice of heavy duty castor manufacturers at present, many domestic manufacturer of casters, the good and bad are intermingled, so, the user should have to choose heavy duty castor manufacturers, and can not blindly pursue low price, in order to avoid because of the reason of castor, causes the damage of the product loaded, cause unnecessary damage to property. Choose the professional heavy-duty casters manufacturers, users can reference from the following points: 1, the regular heavy duty castor manufacturers, general can provide the necessary technical drawings and all relevant parameters; 2, the regular heavy duty castor manufacturers should have professional testing equipment, including castor walking test, load test and other professional castor testing equipment, otherwise, cannot judge caster wheel load requirements.
