Problems solved by technology

Said mechanisms work with mechanical parts, but usually multiple hydraulically operated cranes are required, a lot of work is done in the piping from the pumping station to the crane in question, which can have oil leaks, which poses a risk to the crew on board Dangers of slippery surfaces
The mechanism also needs a lot of parts to get the job done

Embodiment Construction

[0030] This new single lift side rolling hatch cover is designed to be a reliable and cost effective hatch cover for bulk carriers. This will apply to all aspects of hatch covers such as design, purchase, manufacture, installation and repair. These aspects affect the cost of all components involved. In design work, it is always desirable to reduce the number of parts and assemblies to be manipulated. This has been a no-compromise solution to the established standards of the equipment.

[0031] A hydraulic cylinder lifting mechanism is fitted in the middle of the longitudinal hatch coamings at the starboard (SB) and port (PS) sides of the ship. This mechanism acts on one of the panels, while a fork linkage acts on the other panel. Release and lift both panels simultaneously to a rolled position. Hydraulic oil is supplied to the hydraulic cylinders by a local small pump unit fitted near the mechanism and connected to two pipes. To reduce the number of parts and avoid electr...

Abstract

The invention relates to a device (1) at a mechanism in order to effect the operation of displaceably movable hatch covers (3, 4) of ships (2) between a closed (I) and an open (II) position and between an open position (II) and a closed position (I) , respectively, and that comprises actuating means connecting with the respective hatch cover (3, 4). According to the invention, the respective hatch cover (3, 4) is connected to, for instance, a loop- shapedly running, driven pulling rope (6) , as well as that on either side (A, B) of the lateral limiting edge (8, 9 and 10, 11, respectively) of the hatches, there is provided a turnably mounted actuating element (12, 13) , which is detachably inter- connectable with the respective hatch cover (3, 4).

Description

technical field [0001] The invention relates to a device on a mechanism for operating a displaceably movable hatch cover of a vessel between a closed position and an open position and between an open position and a closed position, respectively. Background technique [0002] The above described mechanisms for actuating a displaceable hatch cover of a watercraft are shown as examples in WO2005 / 025977A1 ​​and WO02 / 090175A1 respectively. Said mechanisms work with mechanical parts, but usually multiple hydraulically operated cranes are required, a lot of work is done in the piping from the pumping station to the crane in question, which can have oil leaks, which poses a risk to the crew on board Danger of slippery surfaces. The mechanism also needs a lot of parts to get the job done. [0003] By avoiding the use of hydraulic lines, the following components and work are eliminated: [0004] ●It does not need to be considered as complex hydraulic equipment; [0005] Cutting (o...
