Dump Body Side Rail Structure to Prevent Material Buildup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine bodies, such as dump bodies, experience material spillage and collection on top side rails during loading, leading to inefficiencies in material transport and potential deformation from impact during loading.
Innovation Solution
The design incorporates top side rails with an outwardly and downwardly sloping upper side surface and a flange extending upwardly from the surface, directing material away from the body cavity and protecting the surface from impacts using hardened steel flanges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the top side rail has a flat or inwardly sloping surface, then material can be contained within the body cavity, but material collects on the top side rail causing spillage and potential deformation
Solution Approach 1:
The upper side surface of the top side rail is inverted from the conventional flat or inwardly sloping design to an outwardly and downwardly sloping surface. This inversion causes material to be directed away from the body cavity and off the top side rail, preventing material collection and spillage while maintaining effective material containment within the cavity.
2Productivity
If the top side rail surface is exposed to direct material impact during loading, then loading can proceed efficiently, but the surface deforms from repeated impacts
Solution Approach 1:
The outwardly and downwardly sloping upper side surface converts the harmful impact force from loading operations into a beneficial directing force. Material impacting the sloped surface is automatically directed away from the body cavity, transforming the potential harmful effect of impact into a useful material directing function that protects the surface while maintaining loading efficiency.
3Loss of substance
If material is directed away from the body cavity during loading, then spillage is reduced, but the loading process may be affected
Solution Approach 1:
The top side rail is designed with differentiated local qualities: the flange portion provides a vertical barrier adjacent to the body cavity for material containment, while the upper side surface provides an outwardly and downwardly sloping direction for material discharge. This local differentiation allows material to be contained where needed while being directed away where appropriate, reducing spillage without interfering with the loading operation.

AI summary
The present disclosure provides a body for a machine. The body comprises a front wall at a front end of the body. First and second side walls extend from the front wall to a rear end of the body. The first and second side walls each comprising a top side rail. A base extends from the front wall to the rear end and between the first and second side walls. Thus the front wall, first and second side walls and base at least partially form a body cavity for receiving material. Each top side rail comprises an upper side surface and a flange extending upwardly from the upper side surface adjacent to the body cavity. The upper side surface extends downwardly and outwardly away from the flange for directing material from the top side rail and away from the body cavity.
