Hydraulic hatch cover cranes

Our hydraulic hatch cover cranes (type HLW) are designed to carefully stack and move our renowned "Friesche Kap" or "Frisian Cap" hatch covers. The design of these cranes is especially determined by the height of the carriage in idle status so as to meet the desired crawl-line. In most cases, all hatch covers can be stacked on one pile and the maximum hold opening in container ships can be obtained. Besides the HLW hatch cover crane, there is also a simpler s-HLW hatch cover crane for smaller ships.
