Heavy Load Lifting System with Telescopic Boom and Winch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lifting equipment is often unsafe and lacks versatility for a single person to easily and securely remove and reattach heavy or large vehicle components, such as truck beds or hoods, without risking injury or damage.
Innovation Solution
A heavy load lifting system with an elongated frame on a wheeled base, featuring a height-adjustment carriage, telescopic boom, pivot support assembly, tilt-adjustment mechanism, and winch mechanism, allowing for safe and efficient lifting, tilting, and rotating of vehicle components, along with various attachments for different shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lifting equipment is used, then heavy components can be lifted, but the operator safety is compromised and additional manpower is required
Solution Approach 1:
A mechanical intermediary system (the lifting device with frame, winch, and carriage) is introduced between the operator and the heavy load. The winch mechanism and carriage system act as intermediaries that amplify the operator's input force while providing controlled, safe lifting of heavy components without requiring direct manual handling by the operator.
Solution Approach 2:
The patent replaces manual mechanical lifting (direct human effort) with a mechanical system (winch, pulley, carriage) that uses mechanical advantage to lift heavy loads. This substitution eliminates the need for multiple operators while maintaining safety through controlled mechanical engagement and disengagement mechanisms.
2Adaptability or versatility
If specialized tools are used for specific components, then those components can be removed, but versatility is reduced when working on other equipment
Solution Approach 1:
The lifting device is designed as a universal system that can handle multiple types of vehicle components (truck beds, hoods, doors, etc.) through a single integrated mechanism. The standardized carriage and winch system can accommodate different attachment points and component geometries, eliminating the need for multiple specialized tools while maintaining the ability to work on various equipment types.
3Reliability
If safety features are added to protect the operator, then operator protection is improved, but the device complexity increases
Solution Approach 1:
The system incorporates beforehand cushioning through mechanical safety features built into the lifting mechanism. The carriage design includes inherent mechanical constraints and engagement mechanisms that prevent accidental dropping or uncontrolled movement of the load, providing operator protection through the design itself rather than adding separate complex safety systems.

AI summary
A heavy load lifting system is a system that enables a repairman to safely lift and mount different vehicle components for maintenance or repair. The system may include an elongated frame, a wheeled base, a height-adjustment carriage, a telescopic boom, a pivot support assembly, a tilt-adjustment mechanism, and a winch mechanism. The elongated frame enables the height-adjustment carriage to be raised so that the vehicle component can be removed from the vehicle. The wheeled base enables the system to be moved around. The height-adjustment carriage enables the operator to elevate or lower the telescopic boom. The telescopic boom enables the vehicle component to be removed safely. The pivot support assembly provides additional support to the vehicle component being removed. The tilt-adjustment mechanism enables the telescopic boom to position the removed vehicle component at the desired orientation. The winch mechanism enables the height-adjustment carriage to be moved along the elongated frame.
