Tilt Tray Vehicle Body Pivoting and Tilting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current load carrying vehicles, such as dump trucks and tilt tray vehicles, face challenges in safely unloading earthmoving machinery due to the difficulty in aligning ramps with the vehicle body, leading to safety risks and inefficiencies, especially on uneven ground, and require additional vehicles for transporting materials after machinery unloading.
Innovation Solution
A load carrying vehicle with a movable body capable of pivotal and tilting movement, equipped with releasable pivot means, rollers for support, and a lifting mechanism, allowing the body to be tilted or pivoted for safe and efficient unloading and loading of machinery and materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ramps are used to unload earthmoving machinery from the vehicle body, then the machinery can be transported to site, but the operator has poor visibility of the ramps making alignment difficult and creating safety risks
Solution Approach 1:
The load carrying body is made dynamically reconfigurable between two distinct operational modes: a transport mode with a level floor for stable machinery loading, and an unloading mode where the body tilts and pivots to create a ramp. This dynamic transformation eliminates the need for separate static ramps while providing both stable transport and safe unloading operations with proper operator visibility.
Solution Approach 2:
The load carrying body serves multiple functions: it acts as a stable platform for transporting machinery, transforms into an inclined ramp for unloading machinery, and functions as a dump body for unloading materials. This multi-functionality eliminates the need for separate ramps and additional vehicles, resolving the contradiction between operational ease and safety.
2Productivity
If ramps are used for unloading machinery, then machinery can be loaded and unloaded, but the ramps are heavy and difficult to manipulate, carry and store
Solution Approach 1:
The load carrying body itself is transformed into the unloading ramp through controlled tilting and pivoting movements, eliminating the need for separate ramp structures. This resolves the contradiction by making the ramp function inherent to the vehicle body rather than an external accessory that requires storage and manipulation.
Solution Approach 2:
The vehicle creates its own unloading ramp using its load carrying body, eliminating the need for external ramps. The body's own structure and movement capabilities are utilized to provide the unloading function, making the system self-sufficient and removing the burden of ramp storage and manipulation.
3Productivity
If a dump truck is used to transport earthmoving machinery, then machinery can be transported, but after unloading the vehicle cannot be used for carrying soil or materials requiring a second vehicle
Solution Approach 1:
The vehicle is designed with a load carrying body that can operate in multiple modes: transporting machinery on a level floor, unloading machinery via tilting and pivoting to form a ramp, and carrying materials in a dump body configuration. This multi-functionality allows a single vehicle to replace what would traditionally require two separate vehicles, resolving the contradiction between productivity and vehicle quantity.
4Device complexity
If the load carrying body is fixed in position, then the vehicle structure is simple, but the vehicle cannot tilt or pivot the body for safe unloading and loading operations
Solution Approach 1:
The load carrying body is designed with controlled mobility through pivotal and tilting mechanisms, allowing it to transition between a stable transport position and an inclined unloading position. This dynamic capability enables safe loading and unloading operations while maintaining relatively simple structural implementation through the use of pivot points and support rollers.

AI summary
A load carrying vehicle (10) having a mobile chassis (11) and a load carrying body or tray (15) mounted to the chassis (11) so as to be capable of pivotal movement about a pivot axis defined by a releasable pivot connection (16) between the chassis (11) and body (15) for tipping of the body about a pivot axis. Alternatively the load carrying body (15) may be mounted to the chassis (11) through rollers (19) which permit movement of the body longitudinally of the chassis (11) and tilting movement about a tilt axis.
