Walking frame retarder
A common problem with walking frames is ‘running away’. Where a brake is fitted it is usually not suitable for controlling speed – what is required is a constant preset retarding force.
This device uses a contoured roller, spring loaded onto the tyre. The ‘conflict’ of varying velocity ratio across the width of the roller gives rise to a servo action increasing the retarding force. The Tufnol roller is not lubricated and ensures consistent resistance.
The client feels safer user the walking frame.
