Problems solved by technology

[0027] 4. The trolley on the water side must be between the hinge point of the boom and the balance platform at the end of the boom
[0030] 6. The total manufacturing and maintenance cost of the trolley cable support system is high, which includes the necessary additional length of the boom and girder, two sets of trolleys, pulleys, wheels, axles, winding of the towline, hydraulic pressure Jacks, cable tensioning systems, greater hoisting horsepower required to hoist heavier booms with trolleys, etc.
Expensive due to inability to operate and maintain
As a result, such systems have proven of no practical value in the container crane industry

Embodiment Construction

[0056] In order to describe the preferred embodiments of the present invention, please refer to the drawings. In the drawings, the same reference numerals represent the same elements in the corresponding views. The present invention is a set of steel rope winding support system of a cargo container loading and unloading crane. Figure 1 shows an embodiment of the system. The system has a cargo transport trolley 29, which reciprocates along its horizontal mast 17, and the suspended load is transported below it. The portal frame can be a single beam structure or a double beam structure.

[0057] This system is used for "semi-steel rope trolley" transmission or "balanced rope trolley" transmission, which includes at least a skid-through rope load lifting system that can be moved from a remote location on the crane Drive, and can be electrically and manually controlled. The system also includes an integral cable trolley drive. Refer to Figure 2, which shows the most common load hoistin...

Abstract

A wire rope receiving support system for a cargo container handling crane having a transport trolley mounted for reciprocation along a horizontal gantry thereof and having a wire rope load hoisting system for the transport trolley wherein a mechanism is provided mid span of said gantry for supporting the wire ropes of at least the load hoisting system and permitting the transport trolley to actuate the rope system to let the trolley pass there by without mechanical interference.

Description

Technical field [0001] The invention relates to a gantry crane for loading and unloading cargo containers. More specifically, the present invention relates to an improvement of the steel rope winding system of the cargo container transportation trolley of the crane. In particular, the present invention relates to a wire rope winding support system of a gantry crane, wherein the wire rope system performs cargo lifting and traverse lifting, and is supported at least in the middle of the maximum suspension length of the crane wire rope. Background technique [0002] The cargo container loading and unloading gantry crane benefiting from the improvement provided by the present invention is configured in relative positions for operation, spreading across the ground, wharf, and water surface in a wide vertical area, and transports cargo containers from one storage area to another in a horizontal direction. . Such large gantry cranes are usually set up at the forefront of docks in shippi...
