One of the group’s factories is using a special spring-loaded heavy-duty castor for frames which are used to hold automobile components. A different plant intended to use this castor for a similar purpose.
For a variety of reasons, the company’s technicians wanted to make a few changes to the wheel lock system of the castor to optimise it for the new application. One of their aims was to reduce the significant cost of repairing their existing frames, as the castors which they were using frequently collided with the fork when they were moved with forklifts due to their large collision circle. The wheel brake lever also stuck out quite far when open, which had the potential to cause an injury when used at the other factory. There were also difficulties releasing the wheel lock. The lever had to be pushed upwards, which employees found difficult to do due to the safety shoes they were required to wear. This also frequently caused damage to their shoes.
