Almost every industry around the world, whether large, small or medium, uses wheels in one way or another. The benefits of casters are well known, and the use of the correct model can reduce the risk of accidents and damage to the goods. The idea of introducing damping springs in conventional wheel housing is ingenious, since it solves several difficult problems, namely: reducing the impact and vibration of delicate products, damaging surfaces and reducing noise.
How they work
Most cushioned or spring wheels are made of black painted steel. Essentially, these rollers consist of a modified body to which a sprung suspension is attached. This allows them to absorb sudden jerks when they carry excess weight and protects sensitive loads. This is especially useful when working with large amounts of fragile loads, where a bump caused by an uneven surface can damage the load. The justification for installing springs to absorb the impact on the wheels is simply to reduce the impact caused by the use of a spring deflection strategy. Shock absorbing casters used in industrial environments often come into contact with hard surfaces that can damage sensitive products. Therefore, due to the installation of a shock absorbing or spring loaded roller, the risk of damage to both the load and the handling device is significantly reduced. There is also a further drawback of problems with resonant vibration when the transport equipment is in contact with uneven surfaces. These vibrations are also spread through equipment, which is potentially dangerous not only for the goods, but also for the operator.
In industrial environments, one of the most worrying problems is the noise level. This can be dangerous for the concentration of workers and, therefore, the reduction of environmental noise should be taken very seriously. One of the main factors that contribute to the appearance of noise in industrial plants is the equipment used. Most of them emit a lot of noise and vibrations when they come into contact with uneven surfaces or other mechanisms.
An effective noise control strategy used by several industrial companies around the world is to incorporate damping rollers in their mechanisms. It has been shown to reduce environmental noise, which in turn contributes to improved performance. The installation of damping rollers in machinery and equipment has another advantage, as it increases the useful life of the device.
It is believed that, compared to casters, spring loading can significantly reduce the degeneracy of the equipment, which increases the useful life of the equipment. Shock absorption rollers are used in many industries, including automotive, medical and aerospace industries, in fact, where the equipment is very sensitive, cumbersome or heavy.
