The Lifter from Rock Mills Enterprises safely and efficiently removes manhole covers and drainage grates with the push of a button. It mounts into a standard 2-inch trailer hitch receiver and is powered by the vehicle battery. A roadway camera and dash-mounted monitor positions it directly over the cover, which can be removed via remote control. With an optional swing arm, the cover can be swung away from the opening and replaced after work is completed without moving the vehicle. 712/451-6550; www.rockmillsent.com.
