Profile: Nu-Star Material Handling Ltd. specializes in the design and manufacture of a range of pedestrian operated, battery powered, tug units for pushing and pulling wheeled loads in a wide variety of applications. Our power tug has been specifically developed to move loads up to 2,500Kgs, especially if they have multiple swivel castors. The front leg (or legs) is telescopic and has fixed wheels at the end, these wheels overcome the tendency of loads on swivel castors to wander (like supermarket trolleys) when being moved.
