[Hua Ya] Xiaobian learned from the official website. In fact, one of the most commonly used objects in a factory is the one that is most easily overlooked. In addition to forklifts, one of the key components in the crane series is the “casters”. In fact, forklifts are also good, and the tow trucks are also inseparable from the casters. In fact, the choice of each accessory is a microcosm of the labor productivity of a factory or a workshop. If the casters are broken when the equipment is being transported, it will inevitably affect the progress of the workshop. Let’s introduce it below.
How to choose a caster that suits your product may be a problem for some companies’ purchases. Here I will tell you some factors to consider when choosing a caster:
First, choose the right caster wheel material: usually the wheel material is nylon, rubber, polyurethane, elastic rubber, iron core polyurethane, cast iron, plastic and so on. Polyurethane wheels can meet your handling requirements whether you are driving indoors or outdoors. Elastic rubber wheels can be used on hotels, medical equipment, wooden floors, tiled floors, etc. where noise is required to walk when walking quietly; nylon wheels, The iron wheel is suitable for use on sites where there is uneven ground or iron on the ground.
Second, how to choose the correct caster bracket: usually choose the appropriate caster bracket first consider the weight carried by the caster, such as supermarkets, schools, hospitals, office buildings, hotels, etc., because the ground is good, smooth and the goods are light, (each Only casters are carried in 50-150kg). It is suitable for electroplating wheel frame with 3-4mm stamping. It is light in wheel frame, flexible in operation, quiet and beautiful. This plated wheel frame is divided into double rows of beads and single ball according to the ball arrangement. For the beading, if the moving or handling is carried out, double-row beads are used; in factories and warehouses, the goods are transported frequently and the load is heavy (each caster is carried at 150-680kg), it is suitable to use thick steel plate 5-6 mm stamping. Hot-forged and welded double-row ball cage; if used for carrying heavy objects such as textile factories, automobile factories, machinery factories, etc., due to heavy load and long walking distance (each caster is carried at 700-2500kg), it should The wheel frame is welded after cutting 8-12mm thick steel plate. The movable wheel frame uses flat ball bearing and ball bearing on the bottom plate, so that the caster can bear heavy load, flexible rotation and anti-impact.
Third, how to calculate the carrying weight of the casters: In order to be able to calculate the required load capacity of the various casters, it is necessary to know the weight of the transport equipment, the maximum load and the number of single wheels and casters used. The load capacity required for a single wheel or caster is calculated as follows: T = (E + Z) / M × N: T = required load weight for a single wheel or caster; E = dead weight of the transport equipment; Z = maximum load; M = The number of single wheels and casters used; N = safety factor (about 1.3-1.5).
Fourth, select the diameter of the caster: Generally, the larger the diameter of the wheel, the easier it is to push. The greater the load capacity, the better the ground can be protected from damage. The choice of the size of the wheel diameter should first consider the weight of the load and the load of the truck. Start the thrust to decide.
Fifth, the positive rotation of the wheel is more flexible: the larger the wheel, the more labor-saving, the needle bearing can carry a heavier load, and the resistance is greater when rotating; the high-quality ball bearing on the single wheel can carry a heavier load. The rotation is lighter, more flexible and quiet.
Sixth, the temperature condition of the product: the cold and high temperature occasions have great influence on the casters. For example, the polyurethane wheel has a low temperature at minus 45 ° C, and the rotation is flexible, and the high temperature resistant wheel rotates lightly at a high temperature of 270 ° C.
