Use high quality castor wheels to enhance employee’s safety at workplace
Health, physical fitness and the understanding of their employees that everyone is under excellent care guarantee satisfaction, which means lower sickness rates and higher levels of dedication. For example, workplace safety should be considered a pillar of business culture rather than a legal requirement just on paper or for show.
On smooth hard surfaces, the harder castor wheels with a narrower contact area may roll more easily - but its unit weight will be much higher. Unit load (crushing pressure) is the total load divided by the area of contact. If this pressure is too high, it will damage the floor. In practice, the crushing pressure of a cast iron wheel often exceeds the compressive strength of concrete, especially when the load is more concentrated in expansion gaps, cracks, etc., or when the load is increased by motion and inertia.
In fact, cast iron recommends using them by pulling them. Polyurethane spreads the load sufficiently so as not to damage the floor without greatly increasing the 'push' required. Being highly flexible and abrasion resistant, it is an ideal trial material. Additionally, it softens the weight and prevents damage to the trolley and casters. A concrete floor is probably the most expensive component of any warehouse or factory, so using the right industrial castors wheels will protect it from damage. Rubber is used less or less because it is very difficult to push at high loads. It can be adversely affected by oils, chemicals, etc., and it lasts only 1/5 (or less) of the life of polyurethane.
What makes a good industrial castor in Aeronautics?
In this particular case, we are talking about industrial castors that are used in ground support applications in the aerospace industry. This is a big stand that costs big money. To choose the right heavy-duty caster for this type of application, you need to consider several factors, and this article will highlight the most common ones.
When moving a jet engine onto a stand that can cost more than $40M, it's important to understand the load the stand is experiencing and make sure your casters have the proper safety factor. The Industrial Castors and Wheels are designed and tested to the best standards, which means there is a 4x static factory protection factor and a 2x dynamic protection factor.When running $40M, that may not be enough. In most engine stand cases; manufacturers are looking for a catalogue load rating of four times the rated load. This means that the actual safety factor is 8x dynamic and 16x static. This is where our heavy-duty casters come in. Failure is not an option, and the added expense is worth the assurance that the casters will not fail and damage the jet engine.
Most engine stand casters end up with some type of suspension system depending on the terrain they are used in. With uneven asphalt or concrete, potholes, expansion joints, etc., and the sensitive nature of what the stand carries, it makes sense to invest in spring-loaded or shock-absorbing casters. This helps to keep the loading of the stand uniform and reduce any shocks or vibrations experienced by the jet engine or other cargo. In jack stand operation, shock absorption is necessary for the jack to function properly.
