The Heiniger Evo was the first shearing machine to be manufactured with an electronic safety switch which will stop the machine immediately if a lock up occurs.  It has three speeds - 2700, 3200, 3500rpm to cater for all shearing conditions. The self tensioning belt means less maintenance and less wear and tear. Machines are available with solid or flexi drives with either worm or pin drive and can be adapted to work with a Lister solid drive.
