Side Shifter Actuator Embedded in Load Bearing Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing side shifters for forklift trucks face challenges in protecting the hydraulic actuator from damage while maintaining a clear view and minimizing weight and cost, as the actuator is often exposed and additional protection measures add weight and cost.
Innovation Solution
The actuator is embedded within and surrounded by the weight-bearing components of the side shifter, specifically the fork base top bar and back carriage top bar, providing protection and a larger unobstructed view by integrating it into the structural design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the actuator is exposed in traditional side shifter designs, then the structure is simpler and easier to access, but the actuator is vulnerable to damage and requires additional protective measures that add weight and cost
Solution Approach 1:
The actuator is integrated into the weight-bearing components of the side shifter (fork base top bar and back carriage top bar), merging the protective function with the structural support function. This eliminates the need for separate protective armor while providing robust protection against damage.
Solution Approach 2:
The weight-bearing components serve dual purposes: they provide structural support for the side shifter and simultaneously protect the actuator. This multi-functionality reduces the need for additional protective components, thereby reducing overall weight.
2Reliability
If additional protective measures are added to the actuator, then the actuator is better protected from damage, but the cost and weight of the side shifter increase
Solution Approach 1:
The protective function is merged with the existing weight-bearing components, eliminating the need for separate protective parts. This reduces manufacturing complexity and cost while maintaining actuator protection.
Solution Approach 2:
The weight-bearing components inherently provide protection to the actuator through their structural design. The system uses its own structural elements to protect critical components, eliminating the need for additional protective measures.
3Reliability
If the actuator is embedded in weight-bearing components, then protection and unobstructed view are improved, but the structural design becomes more complex
Solution Approach 1:
The actuator is embedded within the weight-bearing components, merging the protective enclosure with the structural support elements. This integration provides protection while maintaining structural integrity without requiring separate protective housings.
Solution Approach 2:
The weight-bearing components serve multiple functions: structural support, load transmission, and actuator protection. This multi-functionality reduces the need for additional components and simplifies the overall design despite the embedded arrangement.

AI summary
A side shifter configured for use on a lift truck with an actuator of the side shifter embedded in and almost completely surrounded by the weight bearing components of the side shifter, particularly the fork base top bar and back carriage top bar. This arrangement provides additional protection to the actuator. Embedding the actuator in the weight bearing components of the side shifter also provides for a larger unobstructed view through the middle side shifter.
