The OZ Lifting Products Tele-Pro davit crane features an industry-first telescoping boom adjustment while under load. This patented feature provides the user with ultimate control. The supplied ratchet screw jack allows the user to adjust the boom from horizontal to 45-degrees while under load. 360-degree rotation of the crane allows even more benefits. Smart Latch technology at the boom/mast means the Tele-Pro davit cranes require no tools to assemble and the zinc-plated finish provides added corrosion protection. Manual brake winch, or AC and DC electric winches are also available. Individually tested and certified at 125%. Cable assembly and bases sold separately. Made in the USA.
