Hydraulic Dump Bed Cover With Sealing Frame for Dust Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transporting hazardous materials in dump trucks require manual labor to secure tarps, which are labor-intensive and limit the size of the dump bed, and necessitate multiple tarping stations, while also allowing residual dust to escape during transport.
Innovation Solution
A cover for dump beds with a skeleton structure, sealing material, and hydraulic operation that secures to the bed, allowing for automatic opening and closing, and includes tyne pockets for easy installation and removal, minimizing labor and preventing material loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual tarping is used to cover the dump bed, then the dump bed can be covered, but labor intensity increases and dump bed size is limited
Solution Approach 1:
The cover system is automatically deployed and secured using the vehicle's existing hydraulic system, eliminating the need for manual labor. The cover integrates with the dump bed structure and uses hydraulic actuators to open and close automatically, allowing the system to serve itself without external human intervention.
Solution Approach 2:
The cover system serves multiple functions: it seals the dump bed to prevent dust escape, provides structural support for larger bed sizes, and integrates with the existing hydraulic system. The universal design allows it to work with various dump bed configurations while eliminating the need for separate tarping operations.
2Productivity
If manual tarping is used, then the dump bed can be covered, but multiple tarping stations are required
Solution Approach 1:
The cover system merges the covering function directly into the dump bed structure, eliminating the need for separate tarping stations. The cover is integrated with the bed's hydraulic system, combining what were previously separate operations (bed operation and cover application) into a single unified system.
Solution Approach 2:
The cover automatically deploys and secures itself using the vehicle's hydraulic system, eliminating the need for external tarping stations and manual workers. The system serves itself by utilizing the existing hydraulic infrastructure to operate the cover without additional equipment or personnel.
3Reliability
If manual tarping is used, then the dump bed can be covered, but material loss occurs during transport
Solution Approach 1:
The cover utilizes a flexible material that conforms to the dump bed structure, creating an effective seal that prevents dust and material escape. The flexible nature of the cover material allows it to adapt to the bed's shape while maintaining a tight seal during transport.
Solution Approach 2:
The cover automatically seals the dump bed through hydraulic actuation, ensuring consistent and reliable sealing without manual intervention. The self-securing mechanism ensures the seal remains effective throughout transport, preventing material loss.
4Extent of automation
If a cover system is implemented, then labor requirements are reduced, but device complexity increases
Solution Approach 1:
The cover system utilizes the vehicle's existing hydraulic system to operate automatically, eliminating the need for separate control mechanisms. By leveraging the already-present hydraulic infrastructure, the system achieves automation without adding significant complexity.
Solution Approach 2:
The cover system serves multiple functions with a single integrated design: sealing the bed, providing structural support, and enabling automatic operation. This multi-functionality reduces the need for additional components, thereby limiting the increase in overall system complexity.

Function Achieved in This Case
The cover effectively seals the dump bed during transport, reducing labor requirements and preventing material escape, while accommodating larger dump beds and eliminating the need for tarping stations.
Implementation Method 1
one or more hydraulic arms connected thereto and having a free end configured to be anchored to the dump bed. The hydraulic arm(s) are configured to hydraulically connect to a vehicle hydraulic system and to operatively open and close the cover relative to the dump bed of the vehicle

AI summary
Covers for a dump bed of a vehicle have a skeleton of longitudinal side beams having a transverse rib extending therebetween, a head beam, and a tail beam. The skeleton can have a pair of tyne pockets at each of the sides and a cover material defining a closed top with terminal ends of each pair of the tyne pockets exposed. The skeleton can have hinges and hydraulic arms each configured to connect to a dump bed. The hydraulic arms are configured to operatively connect to a vehicle hydraulic system to open and close the cover relative to the dump bed of the vehicle. The generally parallel longitudinal side beams are spaced apart a distance to align with the elongate sides of the dump bed and have sealing material connected thereto and to the head beam and tail beam to sealing engage surfaces of the dump bed.
