Embodiments disclosed herein relate to a protection device and/or system that may include a thimble capable of being placed over a transmission line, such as an electrical power cord, to provide protection in the form of cut resistance, abrasion resistance, and/or impact resistance. In some embodiments, a plurality of thimbles can be placed over the transmission line to form an overlapping arrangement to protect a desired length of the transmission line. While each thimble may be rigid, semi-rigid, and/or flexible, the arrangement can maintain flexibility to allow for many degrees of movement of the electrical power cord even as it is cladded in the protection system.

A road plate moving system and method is disclosed that makes it easier, safer, and more economical to move road plates. A frame detachably attaches to a road plate at the centre of the road plate, and the frame is detachably attached to a vehicle, and the frame is attached to rollers that straddle the road plate and are configured to move in the desired direction of travel. Each roller has a lifting mechanism to adjust the height of the frame relative to the bottom of the rollers. In use, the frame is attached to the road plate, and the road plate is lifted off the ground by the rollers lifting the frame, and the frame and road plate are pulled forward or backwards by the vehicle to move the road plate, which is then lowered to the ground. In a second embodiment, the road plate is lifted by a lifter located above the centre of the road plate.
