Extruded Chain Rail for High-Speed Trailer Unloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reciprocating floor slat conveyer systems for unloading trailers are slow and inefficient for palletized loads, limiting unloading speed and maximizing the gross hauling weight of trailers.
Innovation Solution
A modular chain rail loading system comprising independently mountable elongated rails with endless chains and rotatable sprockets, allowing for high-speed loading and unloading, and designed for easy installation and removal on existing trailer floors using hollow extrusions and adjustable fastening systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If reciprocating floor slat conveyer systems are used for unloading trailers, then the system can handle bulk materials, but the unloading speed is slow and inefficient
Solution Approach 1:
The floor slat conveyer system is divided into multiple independently controllable sections or modules. Each section can be activated or deactivated based on the unloading requirements, allowing for optimized throughput and reduced bottlenecks in the unloading process
Solution Approach 2:
The conveyer system incorporates variable speed control and dynamic adjustment capabilities, allowing the unloading speed to be optimized in real-time based on load characteristics and destination requirements, thereby increasing overall productivity
2Productivity
If reciprocating floor slat conveyer systems are installed in trailers, then unloading capability is provided, but the gross hauling weight is reduced
Solution Approach 1:
The conveyer system utilizes thin, lightweight floor slats and support structures that provide the necessary mechanical function while minimizing weight. The flexible design allows for adequate support with reduced material usage, preserving gross hauling weight
Solution Approach 2:
The conveyer components are constructed using composite materials that offer high strength-to-weight ratios, providing durable unloading functionality while keeping the overall system weight minimal to maximize trailer hauling capacity
3Adaptability or versatility
If conventional conveyer systems are built into the trailer floor, then unloading function is integrated, but installation complexity increases
Solution Approach 1:
The conveyer system is designed as modular segments that can be independently installed and removed. Each module contains integrated mounting features that simplify attachment to the trailer floor, reducing overall installation complexity while maintaining adaptability
Solution Approach 2:
The conveyer system incorporates universal mounting interfaces and standardized components that can be adapted to different trailer floor configurations. This multi-functional design allows the same system to be installed across various trailer types without custom fabrication

AI summary
The load conveyer system includes a pair of rails that carry endless chains. Each rail is an extrusion that has extruded side channel portions that allow the adjustable positioning of mounting bracket fasteners. This allows mounting brackets to be used to removably mount the rails to a preexisting floor surface without substantially modifying the floor during the rail installation or removal process.
