Hatch Covers

Hydraulic hatch cranes
in aluminium

Blommaert hydraulic hatch cranes are designed to enable Frisian-style hatch covers and other stackable marine hatch covers to be carefully stacked and moved. This combination is ideal because it ensures that all the elements in each project are coordinated. The most commonly used are the type HLW hatch cranes, either in the retractable version or otherwise (because of gangway width). We also make s-HLW hatch cranes or manually operated hatch cranes for smaller vessels, tug-pushed barges and vessels that need to open and close occasionally or do not have a power supply.
