Tractor-Container Lifting Mechanism for Trailer-Free Hauling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for moving cargo shipping containers require trailers and cranes, which are inefficient and necessitate multiple operators, especially when transferring containers between different transportation modes.
Innovation Solution
A system comprising a tractor and two units that attach to the front and back of a cargo shipping container, using hydraulic cylinders to lift and haul it without a trailer, allowing a single driver to move containers at highway speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If trailers and cranes are used to move cargo shipping containers, then containers can be transported between locations, but the system requires multiple operators and cannot operate at highway speeds
Solution Approach 1:
The patent combines the functions of trailers, cranes, and positioning equipment into a single integrated vehicularization system. The container itself becomes the vehicle body, with integrated lifting mechanisms at both ends that can autonomously position and secure the container, eliminating the need for separate trailer and crane operations and enabling highway-speed transportation.
Solution Approach 2:
The system enables the container to serve itself by incorporating lifting and positioning mechanisms directly on the container. The container can be autonomously lifted, positioned, and secured without external cranes or multiple operators, allowing a single driver to operate the system at highway speeds.
2Adaptability or versatility
If trailers are used to transport cargo shipping containers, then containers can be moved between locations, but the system requires a trailer and cannot operate without it
Solution Approach 1:
The patent extracts the trailer from the transportation system and replaces it with the container itself serving as the vehicle body. The container is equipped with integrated lifting and positioning mechanisms, eliminating the need for separate trailer equipment and reducing system complexity while maintaining operational flexibility.
Solution Approach 2:
The container is designed to perform multiple functions: it serves as both the cargo carrier and the vehicle body, with integrated lifting mechanisms that enable it to be self-sufficient. This multi-functionality eliminates the need for specialized trailers and cranes, reducing device complexity while maintaining adaptability.
3Productivity
If cranes are used to load and unload cargo shipping containers, then containers can be transferred between transportation modes, but the process requires multiple operators and reduces efficiency
Solution Approach 1:
The patent merges the functions of cranes, trailers, and positioning equipment into a single integrated system where the container itself performs loading and unloading operations. This consolidation eliminates the need for multiple operators and external crane equipment, significantly improving logistical efficiency.
Solution Approach 2:
The container is equipped with self-service capabilities through integrated lifting and positioning mechanisms that enable autonomous loading and unloading operations. This eliminates the need for external cranes and multiple operators, thereby improving productivity and logistical efficiency.

Function Achieved in This Case
Enables efficient, trailer-free transportation of cargo shipping containers between locations, including those without loading docks, reducing operational complexity and eliminating the need for cranes in most scenarios.
Implementation Method 1
The first and second units may then lift the container and be hauled away by the tractor

AI summary
A system and method for moving cargo shipping containers includes a tractor with a first unit and a separate second unit. The first and second units grip the front and back ends of the container to lift it, using the tractor for the front chassis and the second unit for the back chassis. The cargo container becomes its own trailer. The second unit may be towed by the tractor behind the first unit, maneuvered into position at the back of the container, and then coupled to the container for lifting. The tractor may then position the first unit to the front of the container for attachment, and then proceed to a destination. Hydraulic cylinders operated off the tractor's power take off provide the lifting force.
