Dump Body Mounting With Sliding Channel Connection for Faster Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of dump bodies to truck chassis is time-consuming due to the need for multiple adjustments and connections in the hinge and lifting assemblies, leading to increased assembly times.
Innovation Solution
The use of a subframe with C-shaped mounts on the dump body's underside, which slidingly receive a connecting member of the dump body lifting assembly, reducing the number of parts and assembly time, and facilitating the connection to the truck chassis, along with a hinge assembly connected on both the dump body and subframe for easier pivoting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hinge assembly and lifting assembly are installed using conventional methods with multiple adjustments, then the connection is secure and functional, but the assembly time increases significantly
Solution Approach 1:
The hinge assembly components are pre-assembled on the dump body before installation on the truck chassis. The connecting members are pre-positioned in the channels of the mounts, and the hinge pins are pre-installed on the dump body. This preliminary assembly reduces the number of adjustments needed during final installation, thereby reducing assembly time while maintaining connection security.
Solution Approach 2:
The hinge assembly is divided into separate components that can be independently assembled and positioned. The hinge body, hinge pins, and connecting members are separate elements that can be pre-assembled on the dump body and then quickly connected to the chassis, eliminating the need for complex in-situ adjustments.
2Reliability
If multiple separate components are used for the hinge and lifting assemblies, then the connection is secure and adjustable, but the number of parts increases and assembly complexity increases
Solution Approach 1:
The hinge assembly components are combined and pre-assembled on the dump body as an integrated unit. The hinge body, hinge pins, and connecting members are assembled together on the dump body before installation, reducing the number of separate parts that need to be handled and connected during final assembly.
Solution Approach 2:
The hinge assembly is designed to perform multiple functions: it provides the pivot connection between the dump body and chassis, and it also serves as the mounting structure for the lifting assembly connecting members. The channels in the mounts serve both as structural elements and as guides for the lifting assembly connecting members, reducing the need for separate components.
3Ease of operation
If the hinge assembly is provided as a complete unit for connection to chassis and dump body, then installation is straightforward, but adjustments are needed that increase assembly time
Solution Approach 1:
The necessary adjustments and positioning are performed in advance on the dump body. The hinge pins are pre-installed, the connecting members are pre-positioned in the channels, and the alignment is pre-established. This preliminary preparation eliminates the need for time-consuming adjustments during final installation on the chassis.
Solution Approach 2:
The hinge assembly incorporates movable elements such as the connecting members that can slide in the channels, allowing for easy adjustment and positioning. This dynamic design enables quick adaptation during installation without requiring complex adjustment procedures, thereby reducing assembly time while maintaining installation simplicity.

AI summary
A dump body pivotally connected to a subframe mounted on a chassis of a truck. The dump body has a floor and at least one mount connected to an underside of the floor, and the at least one mount defines a channel having an open end. The truck further has a dump body lifting assembly operatively connected between the subframe and the dump body for pivoting the dump body relative to the subframe, the dump body lifting assembly having a connecting member received in the open end of the channel. A method of assembling the dump body to the subframe is also provided.
