Heavy-duty wheels, double bearing 4 'universal wheels with brake mute casters polyurethane PU castor is a general designation, including activities and fixed castor. Castor also is what we call the universal wheel, its structure is allowed to rotate 360 degrees; Fixed castor no rotational structure, can't turn. Usually two casters are generally use collocation, such as the structure of the trolley is in front of two fixed wheel, behind near the armrest is driven by two wheels. How to select the appropriate wheel 1, select material: first consider using the size of the pavement, obstacles, and use the residual material on site ( 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. Calculate the load of a single caster to offer certain insurance coefficient, relatively flat on the ground, a single caster wheel load = ( Equipment had been present on the caster and quantity) ×1. 2 ( Insurance coefficient) ; If the ground not level off, the algorithm for the total weight of a single 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 greatly reduce or castor life lead to accidents. 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. Brakes: from the function, the brake wheel, brake bracket wanxiang, both with brake is double brake, and tread brake, brake, brake, etc.
