Mile Marker Hydraulic Winches Winch Systems have been a self- icon for over a decade. This legendary system utilizes the vehicles OEM power steering pump as its power source. Mile Marker chose to design a winch which captures this continuous power supply over the battery power used by competitors. After rigorous testing, we learned it was the right choice, creating a continuous duty system without battery drain, functional both submerged in water and covered in mud. The Hydraulic Winches Winch system is the choice of the United States Army, as Mile Marker became the primary self- outfitter for the HMMWV (Hummer) as well as many other tactical vehicles around the globe.
