  • Features

    Features

    • Durable Rope Guide ensures wire rope tightly in drum.
    • Din Hook with 360° rotation.
    • In build Hoist Panel with plug and socket connections.
    • Controll pendant unit controls two hoists for combined operation or for one hoist operation.

    Safety

    • Rope safety as recommended by FEM norms.
    • When using both the hoist at same time the total load capacity lifted should not exceed the minimum lifting capacity in the common frame.
    • E.g.: In 16T/10T model the load should not exceed the 10T.
