Flair obtained the new patent of Taiwan handwheel clutch in 2016. This component is used in clutch safety handwheel (HAR-CL / HQI-CL). The specially designed clutch prevents the handwheel from rotating with the machine shaft, so when the machine is in operation, the handwheel will not rotate quickly with the machine, but will remain in a static position to protect the operator. If the operator need to operate the handwheel, just push the handwheel close to the machine shaft , and the hand wheel can be engaged with the mandrel for operation. This product is different from similar products on the market. FLAIR's clutch handwheel is simple to assemble without a keyway, and has a variety of sizes, which can be adapted to different mandrel sizes for replacement.
