1. Select caster material: first consider the size of obstacles on the road surface, use the weight of the slag field (such as iron, oil), environmental conditions (such as high temperature, normal temperature or low temperature) and the capacity of the wheel under different conditions to determine the wheel material choose. For example, rubber wheels are not resistant to acids, oils and chemicals. Ultra-polyurethane wheels, high-strength polyurethane wheels, nylon wheels, steel wheels, and high-temperature-resistant wheels can be used in different special environments.
2. Calculate the bearing weight: In order to be able to calculate the bearing capacity of various casters, it is necessary to know the weight of the transport equipment, the heavy load and the number of single wheels and casters. Give a certain safety factor is a single caster, when the load on the ground is relatively flat, single caster load (= total weight of equipment, number of installed casters) × 1.2 (safety factor); if the ground is uneven, then for a single caster Load algorithm, casters = gross weight of equipment / 3 is not because of what kind of non-smooth theoretical ground always has at least three wheels and supporting equipment, this algorithm is equal to increasing the insurance factor, more reliable, preventing bearing shortages, resulting in greatly reduced accidents or life of casters .
3. Determine the size of the caster diameter. Generally speaking, the larger the diameter of the wheel, the easier it is to push, the greater its load carrying capacity, and the better it protects the ground. The choice of wheel diameter should first consider the weight and starting force of the truck under load.
4. Selection of caster material hardness and hardness: usually nylon wheels, super polyurethane wheels, high-strength polyurethane wheels, high-strength artificial rubber wheels, iron wheels and air wheels. Ultra-high-strength polyurethane wheels, polyurethane wheels for indoor and outdoor ground vehicles, can meet your handling requirements; high-strength artificial rubber wheels can drive to hotels, because medical equipment, floors, wooden floors, and ceramic tiles on the ground require walking The sound is quiet; the nylon wheel and iron wheel are on the ground rough or iron filings and other substances; and the pump wheel is suitable for light load and soft uneven road conditions.
5. Brakes: From a functional point of view, there is a brake wheel, a brake bracket, and both brakes are a double brake, including tread brakes, front brakes, side brakes, etc.
