Rotating Truck Loading Platform with Telescopic Boom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing truck chassis systems for transporting and depositing work machines or cargo are limited by the need for significant maneuvering space and inability to align loads vertically, making them unsuitable for narrow access conditions and requiring special alignment of the chassis for pick-up or drop-off, especially when dealing with track systems.
Innovation Solution
A multi-axle truck chassis equipped with a telescopic boom that can pivot horizontally and features a rotatable loading platform with a cross-member and a load hook that can rotate freely, allowing for precise alignment and operation within limited spaces without requiring special chassis alignment, using a control unit to limit boom movement and adjust height automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional skip loader with backward swinging boom is used, then loads can be picked up and set down, but significant maneuvering space is required and chassis alignment to the setting-down point is necessary
Solution Approach 1:
The loading platform is made rotatable about a vertical axis, adding a rotational degree of freedom to the traditional skip loader. This allows the boom to approach the setting-down point from different angular positions, eliminating the need for chassis alignment and reducing the maneuvering space required for load operations
2Ease of operation
If a traditional skip loader with fixed boom attachment is used, then loads can be transported, but load alignment by twisting around the vertical axis is impossible
Solution Approach 1:
The loading platform is designed to rotate dynamically about a vertical axis during load operations. This rotational freedom allows the boom and load to be oriented in different directions, enabling load alignment by twisting around the vertical axis while maintaining transport capability
Solution Approach 2:
The system is divided into independently movable components: the loading platform can rotate about the vertical axis while the boom can pivot about the horizontal axis. This segmentation of movement freedoms allows simultaneous achievement of load alignment and transport functions
3Area of stationary object
If the telescopic boom is extended to reach distant points, then coverage area increases, but the boom may collide with overhead obstacles
Solution Approach 1:
A control unit receives input from height sensors that monitor the vertical position of the boom. When the boom approaches a predefined safe distance from overhead obstacles, the control unit automatically limits further extension or adjustment, preventing collision while maximizing the usable coverage area
4Adaptability or versatility
If a loading platform with longitudinal movement mechanics and drives is added, then container loading and unloading is enabled, but device complexity increases
Solution Approach 1:
The rotatable loading platform with telescopic boom serves multiple functions: it can load and unload containers, pick up and set down general cargo, and align loads in various orientations. This multi-functionality eliminates the need for separate longitudinal movement mechanics, reducing device complexity while maintaining versatility

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise pick-up and drop-off of work machines or cargo in narrow access conditions with limited working height, allowing for autonomous operation and reduced maneuvering effort, as the telescopic boom and loading platform can be controlled to maintain a safe distance and align loads efficiently.

AI summary
A truck with a multi-axle chassis for transporting, depositing and picking up an article, in particular, a working machine used particularly at selected track installations is disclosed. The chassis has in the rear region a loading platform which is rotatable relative to the chassis and has a swivelable telescopic boom. A loading surface located on the same level as the loading platform is arranged in front of the loading platform on the chassis and is outfitted with a loading system for transporting the article from the loading platform to the loading surface, and vice versa. The loading platform has the telescopic boom and a gear ring engaged with a drive motor for vertical rotation of the loading platform for enabling the telescopic boom to deposit and pick up the article in an area surrounding the truck.
