Robust energy supply systems and cables for heavy-duty offshore cranes

Cranes wind energy

Rotating energy supply systems and cables, including accessories for leg encircling cranes (LECs): This heavy-duty rotary crane from Liebherr features an energy chain that allows a rotating range of 900°.

Gantry cranes

For this gantry crane on a drilling vessel, a complete energy supply system consisting of plastic energy chains, trough modules and chainflex cables was implemented.

Sheerleg cranes

Heavy cable weights and long travels. "Heavy duty" energy chains for high additional loads provide significant planning reliability for cable guidance on two sheerleg cranes.

Knuckle boom cranes

In the platform of this knuckle-boom crane on a pipe-laying vessel, a rotary module with a compactly laid energy supply system was implemented. It safely guides the data and signal cables and hydraulic lines.
