Compact Forklift Lifting Device with Integrated Sleeve Chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compact lifting devices have a limited crossing capacity and are prone to tilting during transport on forks, leading to potential falls due to suboptimal balance and space constraints for securing mechanisms.
Innovation Solution
Incorporating first and second sleeves on the chassis to receive forks, with a central undercut and indentation in the turret, allowing secure fork insertion and maintaining stability while allowing turret rotation and minimizing height for compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If sleeves are added to receive forks for stable transport, then transport stability is improved, but device complexity increases
Solution Approach 1:
The sleeves are integrated into the chassis structure and serve dual purposes: they provide structural support as part of the chassis framework while simultaneously functioning as receptacles for transport forks. This multi-functionality allows the device to achieve stable transport without adding separate, dedicated components, thereby improving transport stability while minimizing the increase in device complexity.
2Ease of operation
If sleeves are positioned close to the ground for easy handling, then ease of operation is improved, but available space on chassis is reduced
Solution Approach 1:
The chassis structure is segmented to create dedicated spaces for the sleeves at optimal low positions for handling, while other sections of the chassis accommodate the turret rotation mechanisms and cable routing. This segmentation allows the sleeves to be positioned close to the ground for easy handling without interfering with the space requirements of other critical components.
Solution Approach 2:
The sleeves are arranged in a specific spatial configuration on the chassis, utilizing the transverse dimension across from the turret. This dimensional arrangement allows the sleeves to be positioned low on the chassis for easy handling while the turret rotates in a different spatial plane, avoiding interference between the sleeves and turret movement.
3Reliability
If turret rotation mechanism is made bulky for reliable rotation, then reliability is improved, but space for sleeves is reduced
Solution Approach 1:
The turret rotation mechanism utilizes an asymmetric crown and gear system housed within the chassis, where the bulky components are strategically positioned to one side. This asymmetric arrangement creates an open space on the opposite side of the chassis where the sleeves can be installed, allowing both reliable turret rotation and proper sleeve placement without spatial conflict.

AI summary
A lifting device includes a chassis, a turret connected to the chassis so as to rotate around a vertical axis, and a lifting arm, extending between a first end connected to the turret, and a second end connected to a unit for carrying the load. It includes a first sleeve and a second sleeve, each able to receive a respective fork, arranged on the chassis, on either side of the turret, parallel to one another.
