Mobile Flatbed Servicing Platform with Lateral Shift and Safety Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stationary worker platforms for servicing flatbed trucks and trailers often have excessive space between the platform and the flatbed, making servicing difficult and potentially unsafe.
Innovation Solution
A mobile, elongated worker platform that can laterally shift towards and away from the flatbed using a power-operated linear actuator, equipped with a foreign object detection system to prevent collisions and safety gates for protection, allowing for closer positioning and safer access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stationary workers platform is used, then the structure is simple and stable, but the space between the platform and flatbed is excessive making servicing difficult and unsafe
Solution Approach 1:
The platform is transformed from a stationary structure to a mobile one with lateral movement capability through linear actuators. This dynamic adjustment allows the platform to move closer to the flatbed for better servicing access while maintaining structural integrity through the support structure and guide rails that constrain the movement.
2Ease of operation
If the platform moves closer to the flatbed, then servicing becomes easier and safer, but the risk of collision with foreign objects increases
Solution Approach 1:
A photo-electric detection system provides real-time feedback about the presence of foreign objects in the path of the moving platform. When an object is detected, the system automatically stops or reverses the platform movement, preventing collisions while allowing the platform to move close enough for safe and efficient servicing.
3Adaptability or versatility
If a mobile platform with lateral shifting is used, then positioning flexibility is improved, but the device complexity increases
Solution Approach 1:
Manual positioning is replaced with automated linear actuators that provide precise lateral movement control. The actuators are guided by rails to ensure accurate and safe movement, reducing the complexity of manual operation while enhancing positioning flexibility and adaptability.
4Reliability
If safety gates and detection systems are added, then worker safety is improved, but the device complexity and cost increase
Solution Approach 1:
Safety measures including photo-electric detection systems and physical gates are implemented in advance to prevent dangerous situations before they occur. The detection system continuously monitors for foreign objects and automatically stops platform movement when hazards are detected, while gates provide physical barriers, collectively ensuring worker safety through proactive prevention rather than reactive protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates safer and more efficient servicing of flatbeds by allowing the platform to adjust its position relative to the flatbed, preventing collisions and ensuring worker safety through the use of a photo-electric safety system and safety gates.
Implementation Method 1
A foreign object detection apparatus is provided to halt movement of the platform toward the flatbed if an object, such as a person, is detected between the platform and the flatbed

AI summary
A flatbed servicing station provides a mobile elevated workers platform with an elongated deck. The platform is selectively moved toward and away from a flatbed and has safety features for stopping movement of the platform toward the flatbed when a foreign object is detected between the platform and the flatbed. A plurality of side-by-side safety gates are provided on the side of the deck adjacent the flatbed and a guard gate is provided which is positionable across the rear of the flatbed. Safety apparatus is provided to prevent injury of personnel disposed between a platform and a flatbed being serviced.
