Heavy duty caster design and material selection

Heavy duty caster stents design of heavy duty castor, usually using metal materials as the main body, including ordinary steel plate stamping molding, casting molding, die forging steel molding, usually is given priority to with flat plate assembly. Heavy steel plate thickness of castor generally USES 8 mm, 10 mm, 16 mm and more than 20 mm steel plate. Currently, wanda for China petroleum system design of bearing 12 tons of track, castor, USES a 30 mm thick steel plate, plate using 40 mm, effectively guarantee the safety of the products loaded. Heavy universal wheel rotating plate design of heavy duty castor usually adopts the double ball track, stamping forming, heat treatment. For track, universal wheel rotating plate, generally USES the force bigger plane ball bearing or needle roller bearing, cone bearing, can effectively enhance the load capacity of heavy duty castor. For special shock heavy universal wheel, rotating plate using die forging steel, molding, effectively avoid the bolt connection plate welding, a greater intensity of improve the shock resistance of castor. 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.
