Cable protector devices, assemblies, and systems. The cable protection system may include a moveable system with wheels for moving the moveable system across a floor and a cable pusher attached to each of the wheels. Each cable pusher may include a frame with a pair of deflector legs configured to be positioned in front of and behind each wheel in close proximity to the floor. The cable pusher may be magnetically secured to the wheel, and the deflector legs may magnetically connect to the frame. As the wheels spin or rotate, the frame and deflector legs remain stationary, thereby pushing obstacles out of the way.

A method of assembling a mobile electric power generation system comprises providing a generator trailer having an electric generator, a gas turbine trailer having a gas turbine, an exhaust trailer having an exhaust silencer, and an air filter and ventilation trailer having an air inlet device. Each of the trailers further comprise a trailer alignment system. The method includes arranging the gas turbine trailer at a work site such that the generator trailer and the gas turbine trailer are in an end-to-end configuration. The method includes operably coupling each of the exhaust trailer and the air filter and ventilation trailer to the gas turbine trailer, and correcting a position of the at least one of the generator trailer, the gas turbine trailer, the exhaust trailer, and the air filter and ventilation trailer using the trailer alignment system thereof.

A motor vehicle includes apparatus for towing a trailer with a retractable drop leg. A backup camera captures a detection image with a field of view including the trailer. A vehicle controller detects an initiation of driving with the trailer being connected. A pattern memory prestores at least one image pattern indicative of an extended position or a retracted position of the drop leg. An image scanner receives the detection image when the initiation of driving is detected, wherein the image scanner compares the detection image and the at least one image pattern to detect whether the drop leg is in the extended position. A notification device responsive to the image scanner alerts a driver if the extended position is detected.
