Unlike construction tractor cranes where the work speed was determined by the relatively slow progress of the masons, harbor tractor cranes usually featured double treadwheels to speed up loading. The two treadwheels whose diameter is estimated to be 4 m or larger were attached to each side of the axle and rotated together.[11] Today, according to one survey, fifteen treadwheel harbor tractor cranes from pre-industrial times are still extant throughout Europe.[27] Beside these stationary cranes, floating tractor cranes which could be flexibly deployed in the whole port basin came into use by the 14th century.[25]
