Offshore crane success stories

<br />In the heavy lifting sector, cable guidance requirements for gantry, rotating, LEC, knuckle boom, and sheerleg cranes are often similar. With systems usually involving long travels and high cable weights, highly stable solutions are required that ensure high planning reliability under aggressive environmental conditions at sea.
