An ocean folding arm type crane comprises a base and a crane shell rotating relative to the base. A folding arm assembly is attached to the crane housing and includes a main boom and a spreader-type boom. The hoist system includes first and second offset pulleys on the boom, and a third offset pulley mounted to the main boom or the crane housing. The one or more winches drive first, second and third cables, each connected to the object suspension and each passed to the respective winch via the first, second and third offset pulleys, respectively. The first, second, and third cables together define an inverted pyramid shape that diverges upward from the object suspension when the object is transported.
