  • Hydraulic winch overhaul and modification


    We received a disassembled hydraulic winch for inspection. After inspection we carried out overhaul and modification in our workshop:
    • The stainless steel parts: the triangular frame are custom build.
    • The winch drum is blasted and coated with a three-layer seawater resistant coating.
    • Also, the orbit motor, the over center valve, mounting flange, seals and bearings replaced.
    The winch is tested after assembly. The Brevini winch is now seaworthy and ready to be mounted on board.
