Heavy-duty casters refers to the caster wheel load capacity is bigger, is, according to the caster wheel bearing capacity is relatively light castor, medium casters, classify, and no clear boundaries, generally from 500 kg to 15 tons, even higher load castor, called heavy-duty casters.
Heavy duty castor castor English is Heavy duty caster or Heavy duty castor, particularly Heavy load of Heavy duty castor English is Extra Heavy duty casters or Extra Heavy duty castors.
Heavy duty castor stent design: the framework of the heavy-duty casters, 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 wheel industry for China's 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: 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 selection, heavy duty castor is used for heavy equipment moving, 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 wheel diameter choice: according to the diameter of the wheel, 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, our wanda wheel industry is the low center of gravity of heavy-duty casters, minimum 2 inches castor, can also be bearing more than 360 kg.
Heavy duty castor manufacturers choose: 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.
