Profile: Wetherby Engineering Group specializes in providing precision machining and fabrication service through it's sub-contract machining division. A large variety of work can be tackled due to our wide range of machine types which include horizontal & vertical machining centers, CNC lathes & drills, horizontal borers, cylindrical & surface grinding and keyseater. We offer automatic centrifugal brake. This automatic brake combines simplicity, reliability and efficiency. Working parts are confided to a stationary brake outer, and a center in the form of a spider carrying four spiral spring controlled shoes bonded with friction material on the outer face. The springs hold back the shoes whilst lifting the load under power, but while lowering under gravity at a pre-determined higher speed, the shoes are thrown radially outward and engage with the brake outer, thus controlling and lowering the speed.
