NEW MULTI-FOLD HATCH COVER SYSTEM FROM MACGREGOR

A new non-hydraulic hatch cover system for weather decks has been brought out by the MacGregor organisation. This Direct Pull semi-automatic concept, as it is known, is a multi-fold system for ships with cargo gear, offering, it is claimed, a 30 per cent reduction in costs over hydraulic systems. Cross-joint sealing by fixed-hinge and auto-wedge cleating ensures good water-tightness, while cargo can be secured quickly against rain since closing relies on gravity only. Deck cranes or derricks are used to open and close the three-part covers, a wire being passed through a single sheave to a point of pull at the farthest panel. The hinged sheave stows below top plate level, leaving the covers clear for deck cargo. No stowage ramps are needed with this system, and the covers are said to be easy to install and maintain.
