Reach Forklift Load Wheel Mounting for Jack-Free Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reach type forklift trucks require external jack equipment for load wheel replacement, making the process difficult and time-consuming.
Innovation Solution
A load wheel mounting structure that includes a wheel assembly with a rotatably mounted load wheel and an outer frame, allowing for easy assembly and disassembly by a single bolt, and enabling load wheel replacement without external jacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional load wheel mounting structure is used, then the load wheel can be mounted on reach legs, but external jack equipment is required for replacement making the process difficult and time-consuming
Solution Approach 1:
The mounting structure is divided into separable components: the outer frame with integrated jack mechanism, the wheel assembly with side plates, and the bolt connection system. This segmentation allows the wheel assembly to be independently removed and reattached without requiring external jack equipment, directly resolving the contradiction between ease of replacement and structural complexity
Solution Approach 2:
The outer frame incorporates an integrated jack mechanism that enables the forklift to lift its own reach legs for wheel replacement without external equipment. The single bolt design allows the wheel assembly to be easily detached and reattached by manual operation, making the system self-sufficient and eliminating the need for external jack equipment
2Productivity
If conventional load wheel mounting structure is used, then the load wheel is securely mounted, but replacement requires external jack equipment and involves difficulties in assembling and disassembling
Solution Approach 1:
The outer frame is pre-configured with the jack mechanism and bolt holes positioned to automatically align with the wheel assembly during insertion. The tapered guide holes are预先 designed to guide the bolts into correct positions, eliminating the need for complex alignment procedures during assembly and disassembly, thus increasing replacement speed while maintaining ease of manufacture
Solution Approach 2:
The mounting structure transitions from a static rigid connection to a dynamic removable connection. The wheel assembly can be quickly inserted and secured with a single bolt, or rapidly removed by unscrewing the bolt. This dynamic design allows flexible adaptation between secure mounting and quick replacement, resolving the contradiction between productivity and ease of assembly
