Container Mobility Lift with Roller Wheel Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting devices for shipping containers are inefficient in lifting and moving containers due to limited mobility and stability, particularly when attempting to lift and roll multiple containers simultaneously.
Innovation Solution
A container mobility lift device with a rotatable end frame, extension member, and support frame configuration that allows for upward movement and rolling of shipping containers, utilizing a roller wheel for enhanced mobility and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional lifting devices are used to lift shipping containers, then the containers can be lifted, but the devices have limited mobility and cannot efficiently handle multiple containers simultaneously
Solution Approach 1:
The lifting device incorporates a roller wheel that can transition between a storage position and a deployed position. When deployed, the roller wheel enables the container to be rolled on a surface, providing dynamic mobility. The roller wheel is affixed to the support frame and can rotate freely, allowing the container to be easily moved horizontally after lifting, thus resolving the contradiction between lifting capability and mobility.
2Ease of operation
If multiple lifting devices are used to lift and roll containers simultaneously, then mobility is improved, but the stability and force distribution becomes more complex
Solution Approach 1:
The device combines multiple functions into a single integrated structure: the end frame engages with the container, the extension member provides lifting force, the support frame provides structural support, and the roller wheel provides mobility. This merging of functions ensures that when multiple devices are used, the force distribution and stability are maintained through the unified mechanical structure, resolving the contradiction between rolling capability and force distribution stability.
Applied Scientific Principles
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 efficient lifting and rolling of shipping containers by distributing the lifting force effectively across multiple devices, improving mobility and stability, allowing for secure and efficient handling of multiple containers.
Implementation Method 1
A roller wheel is affixed to the support frame and allows the shipping container to be rolled on a surface
Implementation Method 2
A roller wheel is affixed to the support frame and allows the shipping container to be rolled on a surface
Implementation Method 3
An extension member is rotatably connected to the end frame at a rearward upper pivot point. A support frame is rotatably affixed to the end frame at a rearward lower pivot point. The support frame is further rotatably affixed to the extension member at a forward upper pivot point. Extension of the extension member rotates the support frame with respect to the end plate, causing the support frame to move the end plate upwards

AI summary
A lifting device for lifting shipping containers has an end frame configured to engage with a shipping container. An extension member is rotatably connected to the end frame at a rearward upper pivot point. A support frame is rotatably affixed to the end frame at a rearward lower pivot point. The support frame is further rotatably affixed to the extension member at a forward upper pivot point. Extension of the extension member rotates the support frame with respect to the end plate, causing the support frame to move the end plate upwards, the end plate then lifting the shipping container. A roller wheel is affixed to the support frame and allows the shipping container to be rolled on a surface when multiple devices are used to lift the shipping container off of the surface.
