Hatch Cover Gantry Crane – Rail-Travelling Hatch Crane for Bulk Carriers

A hatch cover gantry crane travels on deck rails along the hatch coamings, lifts each pontoon hatch cover with a spreader and stacks it on the next hold. Holds can be opened and closed without a shore crane. Marine Crane designs and builds hatch cover gantry cranes in Türkiye for bulk carriers, multi-purpose cargo ships and barges.

Capacity range and options

Span, lifting height and SWL are designed for the hatch cover weight and the hold layout of each ship. Send the general arrangement and hatch cover drawings and we prepare a proposal.

Typical vessels and applications

  • Bulk carriers
  • Multi-purpose and general cargo ships
  • Hatch-covered barges
  • Conversion and retrofit projects

Engineering details

Structure and travel

  • Portal of welded box girders spanning the hatch opening
  • Four travel bogies with hydraulic orbit motors on deck rails
  • Storm locks and rail end stops

Hoisting and spreader

  • Two hydraulic hoist cylinders with 2:1 wire rope reeving
  • Spreader with guide rollers and lift pins that lock into the hatch cover
  • 37 kW hydraulic power unit with proportional valves

Interlocks

  • No travel unless the spreader is in the upper position
  • No lifting unless all lift pins are locked
  • Emergency stop at the operator station and on the portal

Testing and documentation

  • Static load test with test weights according to the applicable class or national rules (for cranes up to 20 t SWL typically 1.25 × SWL)
  • Functional test of all motions, limits, brakes and the emergency stop
  • Delivered with general arrangement, load chart, hydraulic and electrical diagrams, foundation loads, operation and maintenance manual, spare parts list and test certificates

Frequently asked questions

Why use a gantry crane for hatch covers?

The ship can open and close its holds in any port without waiting for shore cranes, and covers are handled with a fixed, repeatable sequence.

Can a gantry crane be fitted to an existing ship?

Yes. Rails and the portal are designed to suit the existing coamings and deck structure.
