The William Hackett Geared Trolley is designed, developed and tested in the UK. It has 2 bars which creates greater stability and has various sized spacers which are used to determine the distance between the 2 plates and the beam width. The trolley is maneuvered along the beam by pulling the hand chain which is attached to a drive gear. This is helpful when the trolley is suspended out of reach. We can offer training on safe use and inspection.
