Universal wheel, adjust the foot manufacturers on the pavement at present double castor consumption about seven. In 140000, pavement two-wheel castor. Development will be faster than the development of the manufacturing industry in castor, in developed countries, our country road two-wheel castor is increased by 2% each year in the proportion of castor domain estimate packing demand growth this year will reach 30. It approximately 9% think pavement two-wheel castor demand growth, pavement two-wheel trundle demand is and 9 this year. 340000. Everyone knows the road barrier ability to promote the energy, the obstacle ability the better, because the two-wheel castor first western industrialization in the late 19th century, so the two-wheel castor generally in inches, such as China's supermarket trolley mostly with 5 inch, 4 inch double castor. The current market popular two-wheel castor size from 1 to 10 inches, the size of the commonly used 2 inch, 2. 5 inch and 3 inch, 3. 5 inch and 4 inch, 5 inch, 6 ', 8 ', 10 ', such as general often need to promote such as supermarket shopping cart, logistics trolley, factory use 46 inch double castor is preferred. Too much but double foot wheel diameter can make equipment center of gravity rises, the cost increase, so must carry on the comprehensive consideration. If the device does not need to often push, such as furniture, refrigerator, etc. , only need to move, when cleaning choose 3 inches below the two-wheel castor. See bearing: the same diameter double castor, general manufacturers can produce several series for different bearing, such as light, medium, medium, etc. , method is to make the wheels and stents have different thickness or material. Calculate a single double caster wheel load to offer certain insurance coefficient, when the ground is flat, a single caster wheel load = ( Equipment had been present on the number of casters) 1. 2) insurance coefficient If the ground not level off, the algorithm for single double the total weight of caster wheel load = equipment present 3 because no matter what kind of uneven ground, always at least three wheels support equipment at the same time, the algorithm is equal to increase the coefficient of insurance, more reliable, to prevent the bearing is not enough, lead to the caster wheel life greatly reduce or lead to accidents. Foreign companies, bearing generally expressed in pounds, and most domestic use kg, conversion relation is 2. 2 pounds = 1 kg. Choose size: general two-wheeled caster wheel diameter is larger. TPR, PP, rubber, nylon, etc. , as applicable, such as temperature, surface hardness, ground environment. Installation method: general light load can be used in the wire rod, rod, plastic expansion sleeve, overloaded with floor, or directly welded to the device. The general mode of large company installation is very rich. Brakes: from the function, with brake wheel brake bracket universal both with brake is double brake, and tread brake, brake, the brake side, contact the castor plant. The arrangement of two-wheel casters on the device.
