Mobile Base for Dump Body Cylinder Lateral Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing equipment with pivotably mounted dump bodies experiences strong lateral pressure on the body lift cylinder when lifting a dump body on uneven surfaces, leading to potential damage due to direct transmission of deflection angles.
Innovation Solution
A mobile base is mounted on the frame to allow transversal inclination of the body lift cylinder, comprising a support with tubular shafts and holding sleeves or an annular support with rotating and tilting capabilities, enabling the cylinder to extend in a straight line even under lateral torsion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the body lift cylinder is rigidly mounted to the frame, then the structure is simple and stable, but strong lateral pressure and torsion are transmitted to the cylinder when lifting on uneven surfaces
Solution Approach 1:
The mobile base is designed with degrees of freedom that allow it to dynamically adapt its position and orientation in response to lateral forces and torsion during dump body lifting. The base can move transversally and rotate to accommodate frame inclination, converting the rigid mounting into a dynamic system that absorbs harmful stresses while maintaining operational stability.
Solution Approach 2:
The mobile base acts as an intermediary element between the frame and the body lift cylinder. It absorbs and redistributes lateral pressures and torsional forces through its mobile structure, preventing these harmful factors from being directly transmitted to the cylinder while still providing stable support for the lifting operation.
2Device complexity
If the body lift cylinder is rigidly mounted to the frame, then the mounting structure is simple, but the cylinder is damaged due to direct transmission of deflection angles
Solution Approach 1:
The mobile base introduces dynamic movement capabilities with specific degrees of freedom that allow the cylinder mounting point to adjust its position and orientation. This dynamic adaptation protects the cylinder from damage caused by deflection angles and lateral torsion during operation on uneven surfaces.
Solution Approach 2:
The mobile base serves as a protective intermediary between the frame and the body lift cylinder. It absorbs and dissipates the harmful effects of frame inclination and lateral forces, preventing direct transmission of stress to the cylinder and thereby improving its reliability and service life.
3Object-affected harmful factors
If the mobile base is allowed to pivot transversally, then lateral pressure on the cylinder is reduced, but the device complexity increases
Solution Approach 1:
The mobile base is designed with controlled degrees of freedom that enable transversal pivoting and rotation. This dynamic capability allows the base to automatically adjust its orientation to counteract lateral pressures and torsion during dump body lifting, reducing stress on the cylinder while maintaining a relatively simple overall structure.

AI summary
Disclosed is an equipment of the type comprising a frame on which is mounted a dump body liftable by means of a body lift cylinder having two opposite ends, a first one of these ends being connected to the frame and the other one to the dump body in order to lift it up when the cylinder is extended. This equipment is characterized in that the first end of the cylinder connected to the frame is mounted on a mobile base which is fixed onto the frame in such a manner as to have some liberty of transversal inclination and thus to allow the cylinder to extend in a constant straight line even if a lateral torsion is applied onto the cylinder by the dump body when said dump body is lifted up.
