Reach Forklift Load Wheel Mounting With Top-Insert Wheel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Replacing a load wheel on a reach type forklift truck is cumbersome and requires external jack equipment, 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 the reach legs to be lifted for replacement without external jacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional load wheel replacement method is used, then the load wheel can be replaced, but external jack equipment is required and the process is time-consuming
Solution Approach 1:
The wheel assembly is divided into separable components (wheel assembly and outer frame) that can be independently handled. The wheel assembly can be detached from the outer frame and replaced without moving the entire forklift or using external jacking equipment, enabling quick replacement by simply separating and reattaching the wheel assembly unit.
Solution Approach 2:
The forklift's outer frame itself provides the lifting function through its structure, eliminating the need for external jack equipment. The wheel assembly is designed to be inserted downward from the top of the outer frame and secured with bolts, allowing the forklift to service its own wheel replacement without external assistance.
2Ease of repair
If conventional load wheel replacement method is used, then the load wheel can be replaced, but the process is difficult and requires external equipment
Solution Approach 1:
The wheel assembly is extracted as a separate, self-contained unit from the forklift's outer frame. This extracted wheel assembly can be easily removed and replaced without requiring external jack equipment or complex disassembly procedures, simplifying the repair process significantly.
Solution Approach 2:
The outer frame is designed with universal features that can accommodate wheel assembly replacement without specialized equipment. The standardized interface between the wheel assembly and outer frame allows for easy attachment and detachment using only basic fastening mechanisms, making the system universally serviceable.
3Strength
If the wheel assembly is secured with multiple bolts, then the connection is strong, but the assembly and disassembly process becomes complex and time-consuming
Solution Approach 1:
Instead of using multiple bolts distributed around the wheel assembly, the design uses a minimal number of bolts (two bolts) positioned strategically to provide sufficient connection strength. This partial action approach achieves adequate fastening with fewer fasteners, reducing assembly time while maintaining connection integrity.

AI summary
The present disclosure provides a load wheel mounting structure for a reach type forklift truck, which is used to mount a load wheel on a pair of reach legs that extend forward of the reach type forklift truck, the load wheel mounting structure including: a wheel assembly including the load wheel which is rotatably mounted; and an outer frame that holds the wheel assembly, wherein, after the wheel assembly is inserted downward from the top of the outer frame, the wheel assembly is assembled to the outer frame by a first bolt that is inserted from a side.
