Inline Terminal Overhead Cranes Rail Transfer Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail transfer terminals face bottlenecks and inefficiencies due to limited space for expansion, leading to freight delays and increased fuel consumption and pollution, as they struggle with the manual and inefficient transfer of containers between rail carriers and trucks.
Innovation Solution
The Inline Terminal, Hub and Distribution system employs a 'strip mall' design with overhead cranes for seamless cargo flow, allowing for efficient loading and unloading of containers directly from one train to another, reducing the need for truck traffic and minimizing real estate requirements, and utilizing a dense buffer system for parallel and perpendicular placement of containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional rail transfer terminals are used with manual container transfer, then freight transfer operations can be performed, but severe bottlenecks occur and freight delays result
Solution Approach 1:
The patent replaces manual mechanical operations with an automated overhead crane system that uses computer control to transfer containers between rail cars. This automation eliminates the bottlenecks of manual transfer operations and significantly increases freight transfer efficiency while reducing delays.
Solution Approach 2:
The system enables self-service through automated crane operations that can independently identify, grab, and transfer containers between rail cars without human intervention. The overhead crane system serves itself through programmed sequences, allowing continuous operation without manual reset or repositioning.
2Productivity
If terminal expansion is attempted to accommodate growing freight volumes, then more transfer capacity is available, but little or no right-of-way is available for expansion
Solution Approach 1:
The patent transitions from ground-level horizontal expansion to vertical three-dimensional operations by implementing an overhead crane system. This allows the terminal to accommodate growing freight volumes by utilizing vertical space and overhead movement rather than requiring additional ground area, effectively expanding capacity within the existing right-of-way.
Solution Approach 2:
The overhead crane system serves multiple functions: it can transfer containers between any pair of rail cars, provide temporary storage positions, and adapt to different container types and rail car configurations. This multi-functionality allows a single compact terminal structure to handle diverse freight operations without requiring separate facilities for each function.
3Adaptability or versatility
If containers are moved from terminal to terminal by truck for corridor transfer, then freight can be transferred between long-distance rail carriers, but significant delays, costs and inefficiencies are introduced
Solution Approach 1:
The patent merges multiple rail corridors by enabling direct container transfers between rail cars from different carriers within a single terminal facility. The overhead crane system can grab containers from incoming rail cars and place them onto outgoing rail cars for different destinations, eliminating the need to move containers by truck between separate terminals and significantly reducing transfer time.
4Ease of operation
If truck activity is increased on urban and suburban freeways to move containers, then container transport between terminals is enabled, but fuel consumption and pollution emissions increase
Solution Approach 1:
The patent extracts the container transfer function from the trucking sector and relocates it to the rail sector by implementing direct rail-to-rail transfers. This eliminates the need for truck transportation of containers between terminals, thereby removing the associated fuel consumption and pollution emissions while maintaining transport flexibility through the versatile overhead crane system.

AI summary
An inline terminal system (300), which includes the steps of: (i) transporting (302) a first container with a cargo via an inbound railroad car to a terminal having a plurality of train rails; (ii) picking and placing (304) the first container from the railroad car to a track side location having at least one buffer in proximity to the plurality of train rails, including: (a) rotating the first container at an angle of at least ten or more degrees with respect to the train rails; and (b) positioning the at least one buffer substantially adjacent to the train rails, at the track side location, at an angle of at least ten or more degrees with respect to the train rails; and (iii) moving (306) the first container via a tractor truck to a desired location for unloading. This system provides a simple, robust and efficient method to load, and in the reverse unload, a container on a chassis or rail car, respectively.
