The Automatic Manhole Lid Lifter is a magnetic manhole cover lifter that mounts on a vehicle where the driver uses a remote and camera to remove and lift manhole covers, drainage grates and sewer grates. This innovative product makes the handling of manhole covers safe, fast, and less labor-intensive. The manhole lifter has decreased workman’s comp claims and eliminates the high costs of work-related injuries and associated administrative expenses by reducing the number of injuries for our clients. This includes back injuries, shoulder injuries, hand, feet and knee injuries.
