Removable Basket for Semi-Trailer Crane Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pocket wagons for combined road-rail transport require semi-trailers to be adapted for crane handling, increasing production costs and limiting the use of most trailers, as well as complicating logistics and requiring skilled personnel and time for operation.
Innovation Solution
Equipping pocket wagons with removable baskets that can be placed and removed using cranes or overhead cranes, allowing semi-trailers to be easily loaded and unloaded without the need for adaptation, and enabling the transport of semi-trailers of different lengths and centers of gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If semi-trailers are adapted for crane handling by reinforcing the frame at grab contact points, then the reliability of transport is improved, but the manufacturing cost increases significantly and the adaptability decreases
Solution Approach 1:
The invention introduces a specialized basket as an intermediary device between the crane and the semi-trailer. The basket is equipped with reinforced contact points that interface with the crane grab, while the semi-trailer itself remains unmodified. This mediator absorbs the structural requirements for crane handling, allowing standard semi-trailers to be transported without frame reinforcement.
2Reliability
If semi-trailers are adapted for crane handling, then the reliability of transport is improved, but the adaptability of the transport system decreases
Solution Approach 1:
The basket serves as a universal intermediary that can accommodate various semi-trailer types without requiring modifications to the trailers themselves. The standardized basket design with appropriate contact points allows different semi-trailers to be loaded onto the same pocket wagon system, greatly enhancing the adaptability and versatility of the transport system.
3Ease of operation
If the pocket wagon uses a fixed basket structure, then the ease of operation is improved, but the adaptability to different semi-trailer lengths and centers of gravity decreases
Solution Approach 1:
The basket is designed with movable and adjustable elements, including adjustable contact points and positioning mechanisms that can be configured according to the specific semi-trailer being transported. This dynamic adaptability allows the same basket structure to safely accommodate semi-trailers of different lengths and center of gravity positions while maintaining ease of operation through standardized loading procedures.
4Adaptability or versatility
If the pocket wagon uses removable baskets that can be placed and removed using cranes, then the adaptability increases and most semi-trailers can be transported, but the device complexity increases
Solution Approach 1:
The pocket wagon system is segmented into distinct modular components: the wagon body, the removable basket, and the semi-trailer. This segmentation allows the basket to be independently designed, manufactured, and replaced as needed. The standardized interfaces between components simplify the overall system while enabling high adaptability, as each module can be optimized independently.

AI summary
The pocket wagon is provided with at least one blade (1), and the dorsal beam (3) of the blade (1) and the crossbeams (4) of the blade (1) support the floor (22) of the basket (20) in such a way that the outermost running belts (22') of the basket (20) are located between the blades (2) and the dorsal beam (3), and the dorsal beam (3) on at least one side of the spurs (1) passes through a torsion beam 8, which is connected to the spurs (2) to form a saddle (9) at the connection point for the pivot support bracket (33) of the fifth wheel trailer (32) into a coupling beam 7 connected to the spurs by a headstock (12). In the pocket (6) of the wagon is placed a basket (20). In the upper portions of the side walls of the basket (20) there are an even number of longitudinal open cut-outs (24), whereby in the portions of the upper walls of the basket (20) between two adjacent cut-outs (24) there are pivotally bearing longitudinal handle arms (25), having a length corresponding to the length of the cut-outs (24), the free ends of which are provided with catches for locking the handle arms (25) in locks (30) located on opposite sides of the two adjacent cut-outs (24).
