Ras Al Khaimah’s Saqr Port Authority has signed a contract for the delivery of two Liebherr LHM 800 mobile harbour cranes configured for the bulk handling of up to 144 tonnes of material at a time.

These two machines will be the biggest mobile harbour cranes for bulk operation in the Middle East upon delivery in 2018, and come with 54m booms, hydrostatic transmissions and Liebherr’s Pactronic hydraulic hybrid drive system.

The Pactronic system uses an accumulator as a secondary energy source by allowing the crane to regenerate and store power when lowering load, and delivering power equivalent to a crane with a larger or secondary prime mover.

The stored energy is transferred back to the system when the crane requires peak power during hoisting, and delivers an up to 30% increase in turnover capacity (2,300 tph) compared to a conventional machine with an equal power rating for its primary energy source.
