Choose your foot wheel correctly

1.choose the wheel material: first consider using the road, the size of the obstacle, the use of ground residual material (e.g., iron filings, grease), environment conditions, such as high temperature and normal temperature or low temperature) and the wheels can carry the weight of the different conditions, such as to choose suitable wheel material.For example, rubber wheels are not acid, grease and chemicals resistant, while super polyurethane wheels, high strength polyurethane wheels, nylon wheels, steel wheels and high temperature resistant wheels are suitable for different special environments.

2. Calculation of bearing weight: in order to be able to calculate the load capacity required by various caster wheels, it is necessary to know the self-weight, maximum load weight of transportation equipment and the number of single wheel and caster used.When calculating the load of a single caster, a certain insurance coefficient shall be given. When the ground is relatively flat, the load of a single caster = (the total weight of the equipment is divided by the number of the caster) * 1.2 (the 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. Selection of soft and hard wheel materials: generally, there are nylon wheels, super polyurethane wheels, high strength polyurethane wheels, high strength artificial rubber wheels, iron wheels and air pumps.Super polyurethane wheel, high strength polyurethane wheel, no matter in the indoor and outdoor ground driving, can meet your handling requirements;High strength artificial rubber wheel can be applied to the hotel, medical equipment, floor, wood floor, tile floor and other requirements when walking on the quiet ground with small noise;Nylon wheels and iron wheels are suitable for places where the ground is uneven or there are iron chips on the ground.The air pump is suitable for light load and soft uneven road surface.

5.Brake: functionally speaking, there is brake wheel, there is brake stand omnidirectional, both the same brake is double brake, and tread brake, positive brake, side brake and so on.
