Hoisting Apparatus Using Temporary Threaded Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hoisting systems for overhead piping and supports are time-consuming and pose safety risks due to the need for workers to secure large, heavy objects at elevated positions, often requiring awkward positions and prohibiting work below suspended materials.
Innovation Solution
A hoisting apparatus featuring a temporary support secured to permanent rods suspended from a ceiling, with temporary threaded rods extending downward and a lifting mechanism to raise a permanent support along these rods, allowing securement before removal of the temporary components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigging apparatuses are used to lift pipes to elevated positions, then pipes can be hoisted to high levels, but the process becomes time-consuming and poses safety risks to workers
Solution Approach 1:
The patent applies preliminary action by securing the pipe to the support structure before lifting it to the elevated position. The support structure is attached to the pipe at ground level, then the entire assembly (pipe + support) is lifted together using rigging equipment. This eliminates the dangerous step of workers accessing the pipe at height to secure it, while also reducing the overall time required since the securing operation is performed on the ground before lifting rather than at elevation.
2Ease of operation
If workers use ladders and scaffolding to access hoisted piping, then they can secure the piping to supports, but they must maintain awkward positions and work below suspended materials is prohibited
Solution Approach 1:
The support structure is attached to the pipe at ground level before lifting, allowing workers to perform the securing operation safely on the ground rather than at elevation. This eliminates the need for ladders and scaffolding entirely.
Solution Approach 2:
The conventional sequence is inverted: instead of lifting the pipe first then securing it at height, the support is attached to the pipe at ground level first, and then the entire assembly is lifted together. This reversal of the operation sequence eliminates the safety hazards associated with working at elevation.
3Reliability
If piping is hoisted to high levels before securing, then the piping can be positioned, but workers face dangerous working conditions below suspended materials
Solution Approach 1:
The pipe is secured to the support structure at ground level before lifting to the elevated position. This preliminary securing action eliminates the safety hazard of working below suspended materials, while the entire process remains efficient since the securing operation is performed on the ground where workers have safe access and proper positioning.

Function Achieved in This Case
This solution enables safe and efficient elevation of pipes and vents by securing them before lifting, eliminating risks associated with unsecured objects and simplifying the process, while being economical and durable.
Implementation Method 1
a lifting mechanism that is adapted to raise the permanent support upwards along the length of the temporary rods
Implementation Method 2
Temporary threaded rods extend vertically downward from the temporary support

AI summary
Described is a hoisting apparatus comprising a temporary support that is adapted to be secured to a pair of vertically disposed, permanent threaded rods suspended from a ceiling. A pair of temporary threaded rods extends vertically downward from the temporary support. A permanent support that is desired to be lifted and secured in an elevated position is engaged with the pair of temporary rods, and a pair of lifting mechanisms is connected to the permanent support and engages with the temporary rods. The lifting mechanism is adapted to raise the permanent support along the length of the temporary rods, and as the permanent support is lifted, it comes into contact with the permanent rods. Once the desired height is reached, the permanent support can be secured to the permanent rods. The temporary support, the pair of temporary rods, and the lifting mechanisms can then be disassembled and removed.
