Pipe Lifting And Transport With Remote-Controlled Mast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lifting devices require multiple operators to lift materials to a desired height and location, causing strain on a single operator during loading, adjustment, and unloading processes.
Innovation Solution
A lifting device with a base, mast, carriage, and integrated lifting and positioning assemblies, powered by battery packs, allowing a single operator to lift and transport materials efficiently by moving the mast and carriage in vertical and lateral directions using remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current lifting devices are used, then materials can be lifted to desired height and location, but multiple operators are required causing strain and increased complexity
Solution Approach 1:
The patent combines multiple lifting mechanisms (first lifting assembly with first cable and first winch, second lifting assembly with second cable and second winch) into a single integrated device controlled by one operator. This merging of functions allows one operator to perform tasks that previously required multiple operators, reducing operator strain while maintaining the ability to lift materials to desired heights and locations.
Solution Approach 2:
The lifting device is designed with multiple cables and winches that can independently or simultaneously lift materials, providing multi-functional capability. The device can handle various loading scenarios (single-operator vs. multi-operator requirements) and adjust its operation mode accordingly, making it universally applicable to different lifting situations while being controlled by a single operator.
2Ease of operation
If manual adjustment is used, then material can be positioned at desired height, but operator strain increases during cranking
Solution Approach 1:
The patent replaces manual cranking operations with automated winch mechanisms. The first winch and second winch are operable to wind and unwind cables automatically, eliminating the need for manual cranking. This substitution reduces operator strain during adjustment while maintaining or improving productivity through automated control.
3Ease of operation
If a single operator is used, then operational simplicity is improved, but lifting capability is reduced
Solution Approach 1:
The patent merges multiple lifting assemblies with their respective cables and winches into a single device controlled by one operator. This combination of mechanical systems provides the cumulative lifting power of multiple assemblies while being operated by a single person, thus maintaining lifting capability while improving ease of operation.
Solution Approach 2:
The device incorporates movable mast portions that can be selectively positioned, allowing the lifting mechanism to adapt its configuration. This dynamic adjustment capability enables a single operator to optimize the lifting arrangement for different load requirements, maintaining adequate lifting power while operating the device alone.

AI summary
A device configured to lift and transport a pipe at a worksite includes a base, a mast coupled to the base, a carriage coupled to the mast, a positioning assembly having a cable that is attachable to the pipe for lifting the pipe from a surface of the worksite to the carriage, upon which the pipe is thereafter supportable, and a lifting assembly configured to move the mast and the carriage to a desired elevation relative to the base to further lift the pipe from the worksite surface.
