SMS-SME Marine Hatch Covers  (5)

Piggy back type hatch cover has been provided on wide open hatch ships for special cargo handling use of 50,000DWT Class type ship actuated by high mount jack up cylinder and self-incorporated drive unit inside of hatch cover and cab-tire type power cable.

SMS-SME is designing and producing various capacity ship use folding hatch covers from 3000DWT to 60000DWT Class bulk carriers driven by hyd. cylinder with control device and reliable power unit resulting more than 200 shipset. The Single folding-type Hatch Cover is a pair consisting of two panels and is driven by a hydraulic cylinder. When the cylinder pushes the panels through the end hinge arm, the hatch cover is folded and moves along the rail at the same time and opened fully. The single folding-type hatch cover can be operated from a specific hatch as necessary. SMS-SME designs and manufactures cleat, wheel, and hinge components to be placed at the most suitable location for smooth operation. The multi folding-type hatch cover consists of a Leading pair and Trailing pair driven by hydraulic cylinder and bell crank respectively. When the leading pair is folded vertically, the trailing pair is pulled up to the stowage position and all hatch covers are opened in sequence. SMS-SME minimizes the stowage space when all hatch covers are fully opened, so the loading space in the cargo hold is increased and loading/unloading of cargo can be easy. SMS-SME supplies hatch covers to multi-purpose carriers which is designed to load various types of cargoes concurrently depending on the types and routes of ships. In case of mixed types of bulk and container ships, various types of cargoes can be loaded effectively by installing folding and pontoon type hatch covers on Weather deck and Tween deck.

SMS-SME has started design development of electric driven hatch cover from 2013 with full size hatch cover trial production as well as compact driving unit development with inverter control for the demand of green energy and energy saving trend, and we are ready for supply to the customers. This hatch cover are driven by the motor driving inverter and PLC. Since hydraulic equipment is not necessary, installation and maintenance can be minimized

Side rolling-type hatch cover is operated by rack gear installed in the transverse direction at the bottom center of each panel which is engaged with the Pinion gear located on the outside of the side deck. Rack & Pinion enable independent drive and allow opening/closing as required. It is optionally available either with auto-roll up system or without it by manual cleat operation for simple and cost saving requirement from the customers. Chain driven type is also available and both arms are connected with chain to operate the two panels on the right and left concurrently. The hatch cover can be operated in both directions using the low-speed hydraulic motor installed on the deck. The Auto-roll up device can be applied like Rack & Pinion driven Hatch Covers.
