DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a process for transportation of a heavy package from vessel to quay or similar loading and unloading location, and vice versa, where there is used a first transportation arrangement for lifting and lowering of the package in a vertical direction and a second transportation arrangement for transporting the package in a horizontal direction between a position outside the vessel and a position inside the vessel, and vice versa.
Furthermore the invention relates to an arrangement for transportation of a heavy package from vessel to quay or similar loading and unloading location, and vice versa, comprising a first transportation arrangement for lifting and lowering the package in a vertical direction and a second transportation arrangement for transportation of the package in a horizontal direction between a position outside the vessel and a position inside the vessel, and vice versa.
In many ports, and particularly at outlying loading and unloading locations with poor access to lifting and transportation equipment for handling heavy packages between vessel and quay and another loading and unloading location, large expenses can be involved in providing suitable lifting equipment simultaneously as the cargo vessel lies ready for loading or unloading. In some instances, local lifting equipment can be employed which is mounted on board in special lifting vessels. In other instances, local lifting equipment can be employed which is mounted on or which is carried on special vehicles. In the foremost instances, the cargo vessel is provided with suitable lifting and transportation equipment, and such equipment will complicate the stability of the cargo vessel to a significant degree during the loading and unloading operation.
With the present invention, the aim is to provide a process for loading and unloading of heavy packages, which can be carried out in a controlled, accurately practicable manner by relatively simple means, without problems for the stability of the cargo vessel. In particular, the objective is to be able to handle packages which by virtue of weight and/or design are difficult to handle with a lifting crane of conventional type. More specifically, the aim is to be able to make oneself independent of special lifting vessels and special vehicles and independent of conventional lifting equipment. The aim is to be able to effect lifting of and transportation of heavy packages between cargo vessel and loading und unloading location by means of easily dismountable equipment which is easy to transport from use location to use location and easy to mount at the use location with adaptation as to height to the free board of the cargo vessel in each individual case. The aim is to be able to carry the lifting and transportation equipment with the cargo vessel itself or with arbitrary transportation means, as required.
The process according to the invention is characterised in that a support member, which carries the package, is alternately lifted and lowered relative to a support element by means of a set of lifting means arranged between the support member and the support element and that the support member and the support element, which are provided with their respective climbing arrangements which are supported separately against the foundation, during the relative lifting and lowering movement between support member and support element, alternately activate their respective climbing arrangements for movement of the support member and the support element in a stepwise lifting movement or in a stepwise lowering movement, the support member being transferred in a horizontal direction relative to the support element prior to and after respectively the stepwise lifting and lowering movement is effected.
According to the invention, the support member with associated package can be raised in a controlled manner relative to the lifting component by means of a number of lifting means between the support member and the support element, while the lifting component is supported against
