By definition from the dictionary, a caster is a small wheel on a swivel attached under a piece of furniture or heavy object to make it easy to move. For the casters, they are designed for the toughest applications like ship and aerospace building many other heavy applications. Long life durability and strength is one criterion one should put into consideration while buying heavy duty casters.
The caster construction material is primarily responsible for giving its chief properties that are strength and durability. Steel made casters are the ones most preferred when it comes to the heavy duty applications since they can provide required weight carrying capacity, mechanical strength. Therefore, one should look for the caster made from the materials that can service the purpose required.
When buying a caster, one should consider whether to get a swiveling or rigid one. Each has its merit and demerits. Rigid caster machines are more like to carry more weight since they do not have many joint and are safer in controlling them. The swiveling casters are more applicable in areas wheel there need to be lots of movements since they can turn at one place without taking much of a space.
Caster wheel wobbling is an effect caused from rapid side to side movement of the wheel during movement. It usually occurs at specific speeds and each caster wheel has its critical speed to which is starts to wobble. The wobble can also be referred as fluttering another contributing factor to the fluttering is the weight borne by the caster wheels. The heavier the load, the less the fluttering since it helps in stabilizing the wheels.
Ergonomic casters are custom designed to suit the environment and situation they are working in. Long time to exposure to resisting caster gear can cause straining injuries to the operators. Therefore, it is important for design improvement and enhancement to help reduce such injuries to the workers. Such improvements include addition of brakes and steering to help in controls, putting toe guards to avoid the caster from running over peoples feet.
The caster wheels come in different sizes in diameters, width and tandems. These factors play a big role in movement. A large diameter wheel caster is usually preferred on rough and irregular surfaces and vice-versa but a smaller diameter caster has more stability compared to a bigger one. Wide caster machines have ability to carrying bigger weights since they distribute the load over a large surface area. A tandem is the arrangement if a caster in a more compact and regular combinations enables them to carry more weight much comfortably without any breakdowns.
Environmental conditions where a caster will be used also dictate the type of caster to buy. The type must be able to work with maximum efficiency with the least maintenance cost. In high temperatures and moist areas, any caster made of metal prone to rusting cannot be advised. In such areas, aluminum and thermal plastics that can stand high temperatures are more applicable. If there is chemical exposure, inert materials like plastics can be used to avoid casters made of reactive metals.
Also the type of caster wheels are dictated by the type of surface or rail being used. When using rails, tapered casters wheels, v-shaped and u-shaped caster wheels are used. For the flat surfaces, flat caster wheels are employed and they can be padded ob tired. This is usually in a bid to reduce vibrations caused and damage to the surface or floor.
