Product Description

Telescopic Boom Marine Crane

A telescopic offshore marine crane allows you to reach a vessel longer. Retracting the telescopic boom with outer telescopic gearboxes will enable you to store it more easily on the deck of your boat, yielding more space on the deck. Enjue uses their telescopic boom marine cranes on five of their lift boats. Make the reach of your lift without compromising the space of your offshore supply vessel with GBM's telescopic boom marine crane.
