Pivoting Load Securing Device for Forklift Mast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load securing devices for lifting carriages restrict the operator's view and vertical height, increase dead weight, and reduce the maximum load capacity, especially when handling narrow or long loads, due to their inflexible design and requirement for hydraulic components.
Innovation Solution
A load securing device with a mast, holding element, and guide rail that allows vertical displacement and pivoting of the holding element, eliminating the need for hydraulic components and enabling compact, lightweight design with a large vertical adjustment range, allowing the holding element to be folded away when not needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a load securing device is installed on the lifting carriage, then load stability is improved, but the operator's view is restricted and vertical height is reduced
Solution Approach 1:
The holding element is designed to be pivotable between a horizontal load-securing position and a vertical retracted position. This dynamic configuration allows the device to provide load stabilization when needed while being folded away to restore the operator's view and vertical clearance when load securing is not required
Solution Approach 2:
The load securing function is separated from the main lifting structure through a独立的 holding element that can be independently positioned. This segmented design allows the holding element to be activated only when needed for specific load types, maintaining operational flexibility while providing stability when required
2Force
If hydraulic components are used in the load securing device, then holding force is improved, but device weight and complexity increase
Solution Approach 1:
The holding element utilizes the gravitational force of the load itself to maintain engagement. When the load is placed on the holding element, gravity automatically keeps the holding element in the horizontal position against the load, eliminating the need for hydraulic actuators or other complex force-application mechanisms
Solution Approach 2:
Hydraulic components and their associated hoses and actuators are completely removed from the design. The force application function is replaced by a passive mechanical arrangement that uses the load's own weight to generate the necessary holding force
3Reliability
If the holding element is always in horizontal position, then load securing is improved, but vertical adjustment range is reduced
Solution Approach 1:
The holding element transitions from a fixed horizontal position to a dynamic configuration that can pivot vertically. This allows the holding element to assume a vertical retracted position that clears the path for vertical movement of the lifting carriage, thereby restoring the full vertical adjustment range while maintaining load securing capability when needed
