Cherry Picker Loading via Remote Control and Boom-Pendulum Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for loading aerial lifts onto trailers or flatbed trucks pose risks of accidents due to operators needing to physically maneuver the lift from the working platform, which can result in injuries during loading and unloading.
Innovation Solution
A method and design for aerial lifts that utilize a remote control unit to maneuver the lift into a loading position before loading, preventing operators from accessing the platform, and allowing the lift to be positioned on the trailer or truck using a compact folded transportation position, reducing the need for physical maneuvering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator manually maneuvers the lift from the working platform during loading, then the loading process can be completed, but the risk of accidents and operator injury increases
Solution Approach 1:
The patent replaces manual mechanical maneuvering from the working platform with remote control operation. The operator uses a remote control unit to operate the lift during loading, eliminating the need to physically access the platform and thereby reducing injury risk while maintaining operational capability.
Solution Approach 2:
The remote control unit serves as an intermediary between the operator and the lift system during loading operations. This intermediary allows the operator to control the lift from a safe distance, avoiding direct exposure to potential hazards while the lift is being maneuvered onto the transport platform.
2Ease of operation
If the lift is kept in working position during loading, then the operator can control it from the platform, but the operator is exposed to injury risks when getting off the platform
Solution Approach 1:
The patent applies preliminary action by requiring the lift to be folded into a compact configuration before the loading maneuver begins. This pre-positioning eliminates the need for the operator to be on the working platform during critical loading operations, removing the injury risk associated with exiting the platform while the lift is in an extended working position.
3Volume of moving object
If the lift is folded to compact transportation position, then it is easier to transport, but it requires additional folding movements and time
Solution Approach 1:
The patent requires the lift to be folded into its compact transportation configuration before being loaded onto the transport platform. This preliminary folding action reduces the overall volume and footprint of the lift during transport, making it easier to handle and transport while accepting the additional time required for the folding operation.

AI summary
A method for loading an aerial lift onto a trailer, the lift including a wheeled chassis, a working platform, a lifting structure including a lifting boom and a pendulum, a remote control unit and an operating unit configured to move the lifting structure, the working platform and the wheeled chassis based on data from the remote control unit.In a loading position and in a compact folded transportation position, the pendulum arm is folded underneath the lifting boom. The method comprises, in order to load the aerial lift onto a trailer, a step of making the lifting structure and the working platform move up to the loading position and a step of using the remote control unit to make the chassis move in order to position the lift, which is in the loading position, on the trailer.
