Description Davit cranes are perfect for permanent or portable installation. These cranes consist of an angled beam which pivots over a vertical axis. They can have fixed or adjustable booms, and are available in portable as well as stationary units. Davit cranes incorporate a hand operated and cable assembly for load handling. Independent bases (Optional-Sold Separately) allow you to move the davit crane from base to base, so one davit crane can serve more than one lift station.
