The choice of the castor

1, choose the wheel material: first consider using the road, the size of the obstacle, the use of ground residual material ( Such as iron, oil) , environment conditions ( Such as high temperature and normal temperature or low temperature) And the wheels can bearing the weight of the different conditions, such as to determine the choice suitable wheel material. For example: rubber wheel can't acid, oil and chemicals, super polyurethane wheel, high-strength polyurethane wheel, nylon wheel, steel and high temperature resistant chakras can apply to different special environment. 2, calculating weight capacity: in order to be able to calculate the load capacity of various casters need must know the weight of transport equipment and maximum load and the number of single wheel and castor. A single wheel load capacities as needed or castor calculation is as follows: T = ( E+Z) / M×N: - - - - - - - - - - - - - T = single wheel or castor to loading weight; - - - - - - - - - - - - - - - - - - E = weight of transportation equipment; - - - - - - - - - - - - - - - - - - Z = maximum load; - - - - - - - - - - - - - - - - - - M = the number of single wheel and castor used; - - - - - - - - - - - - - - - - - - Safety coefficient (N = About 1. 3 - 1. 5) 。 3, determine the wheel diameter size: usually wheel diameter the more the more easy to drive, the greater the load capacity and at the same time, it is to protect the surface from being damaged, wheel diameter size first consideration should be given the choice of bearing and the weight of the load on the truck starting thrust to decide. 4, wheel material soft hard choices: usually have nylon wheel, wheel super polyurethane wheel, high-strength polyurethane wheel, high strength synthetic iron, iron, cheer. Super polyurethane wheel, high-strength polyurethane wheel in both indoor and outdoor floor, can meet the requirements of your handling; High strength synthetic lugs can apply to hotels, medical apparatus and instruments, floors, wooden floor, ceramic tile ground for low noise quiet on the ground when walking driving; Nylon wheel, wheel which can be applied to uneven or there are materials such as scrap iron on the ground; While pep talk round applies to soft light load and road surface is not flat. 5, rotational flexibility: single wheel rotation, the more the greater the effort, roller bearings can carry heavier load, rotational resistance is larger: the single wheel installed on the high quality ( Bearing steel) Ball bearing, can carry heavier load, turn the lighter, flexible peace. 6, the condition of temperature, cold and high temperature occasion has much effect on the caster wheel, polyurethane wheel under 45 ℃ low temperature below zero, rotating flexible, high temperature resistant light wheel under the high temperature of 275 ℃. Special note: because of 3 points define a plane, while the number of used castor for four, deadweight shall be calculated at three. Shanghai castor plant, universal wheel, casters, universal casters
