AI Technical Summary

Benefits of technology

The present invention allows for double the rate of container transfer using a single crane. This is achieved by loading and removing containers onto two trolleys that run along separate travel paths on the crane boom. The travel paths are guided by rails positioned between the container receiving and delivery locations. The spacing between the travel paths and the boom rails allows for unobstructed handling of many containers without delay in transport.

Problems solved by technology

Such container transport cranes have facilities involving factors which limit transport rapidity and efficiency with respect to containers.

Embodiment Construction

[0012]Referring now to the drawing in detail, FIGS. 1, 2 and 3 illustrate a container transfer crane generally referred to by reference numeral 10. Such crane 10 includes a vertical support frame 12 to which a horizontal boom 14 is connected by pairs of cables 16a and 16b. Such cables 16 are fixedly anchored to an upper rectangular end portion 18 of the support frame 12, having four vertical gantry legs 20 extending downwardly therefrom. The boom 14 includes a pair of rails 22 interconnected in laterally spaced relation to each other at their forward and rear ends by end connectors 24 and 26. The frame anchored cables 16a and 16b are connected to the rails 22 adjacent to their forward and rear ends so that the boom 14 is supported in a horizontal position extending through the upper end portion of the support frame 12 in contact with the gantry legs 20.

[0013]The crane 10 is moved to a position on a land-based surface as shown in FIG. 4 by motorized wheel assemblies 28 at the bottom ...

Abstract

Containers are transported by movement of upper and lower trolleys along vertically spaced travel paths established by laterally spaced rails formed in a boom supported in a horizontal position by suspension cables attached to a frame assembly through which the boom extends horizontally between container receiving and delivery locations.

Description

STATEMENT OF GOVERNMENT INTEREST[0001]The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefore.[0002]The present invention relates to guided transport of containers between adjacent locations, such as land-based trucks and dockside moored sea vessels.BACKGROUND OF THE INVENTION[0003]Current methods and apparatus for transport of containers between ships at port and land-based dockside locations involve use of typical marine terminal cranes having a single rail guided trolleys on a boom extending between such container receiving and delivery locations. Such container transport cranes have facilities involving factors which limit transport rapidity and efficiency with respect to containers. It is therefore an important object of the present invention to provide for more efficient container crane loading and unloading of sea vessels to avoid po...
