GB Port Innovation has developed a device to hold the Hatch Cover safely on board the STS crane. It is a simple solution to release quay areas used to stack the hatch covers of the ships.
The device consists of either a platform steel structure, or a special support, attached to the STS crane structure. The hatch covers are stacked on it, using the crane spreader in the same way the crane operator currently handles the hatch covers.
The Hatch Cover Support will be designed according to the size of the container ship.
Depending on the operation needs, the Hatch Cover Support can be a platform steel structure (5), or a support device (6).
The advantage of the small support alternative is that when no hatch covers are deposited on the supports, a container can be handled between both opposite supports when being transferred from or to the ship.
The “Continuous Support”, can be installed in any position, from the front of the crane to its back part. So when the operation is planned, it is possible to select the position that the Hatch Cover will have in each of the cranes that will participate in the operation.
With the “Continuous Support”, it is possible to alternate the position where the hatch cover is placed. In this case, the cranes keep the space between their legs, which allows them to pass containers through.
