The MRT Dolly allows for the easy transport and storage of Wood’s Powr-Grip model MRT4 and MRTA Lifter Series. The lifter and extension arm mounts hold equipment in place securely with cotterless hitch pins. The product’s compact design allows for storage of the lifter in tight spaces. Other features include solid-core tires which hold up to the rigors of regular use and require minimal maintenance, and built-in handles that make it easier to lift into or out of a vehicle when not in use.
