Trunnion Dolly

Trunnion dolly systems are designed for heavy hauling. They can be used for over the road and marine applications. In the photo to the right, HMR Supplies manufactured an 80 Ton Submersible Trunnion Dolly created to dry dock large vessels for vessel maintenance and/or storage. This custom trunnion dolly was designed to oscillate so that the load remains stable over rough terrain. Special submersible components make this trunnion dolly ideal for marine applications.
