Since ages it has been observed the necessity has given birth to invention and it is this very necessity of man that has brought several new inventions into this world. Most of these inventions were done to reduce the manual work that required whole lot of effort in order to be carried out. To reduce the manual effort while doing several regular activities, several products and commodities were invented that really eased our life to a great extent. Castor is one such invention that has allowed the easy mobility of the heavy objects. Today while performing several daily activities we notice that we are able to perform the task with great deal of ease due to the castor attached to it. Castors are small wheel, which are placed beneath objects like furniture, chair and home appliances like refrigerators, washing machine, coolers, and TV trolleys to increase their mobility.
Castors attached to furniture and other object not only proves helpful in easy moving of these objects but it also simplifies and eases the tasks. Without castors attached to these objects it will be extremely difficult to move these objects from one place to another. Therefore, every object that are designed and manufactured today is made with castors attached to it. Due to the excessive use of the castor across different areas, manufacturers have come out with different type and designs of castors that are made to cater the basic mobility requirements of the stuff. Castors are made from different material like Polyurethane, Nylon, Aluminium, Stainless Steel, which are chosen according to the products in which it has to be attached. The other basic things that need to be considered is the diameter of the wheel, the larger is the wheel diameter, less resistance would be faced by the castors, thereby requiring less effort to move the stuff around.
Gone are the days when castors usages were just restricted to furniture and other heavy utility products, today castors are being excessively used across industry verticals. This simple and small invention has just proved its significance in carrying out some mundane and difficult tasks.
