Communication Cabinet Level-Lift Caster Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transporting heavy communication cabinets, such as fiber optic equipment cabinets, is challenging due to their weight and increasing size, which poses safety risks during tilting and maneuverability issues, especially when navigating obstacles like elevator gaps and thresholds.
Innovation Solution
A lifting and transport system with large caster wheels and support bars that attach to the cabinet frame, allowing safe lifting and maneuvering without tilting, enabling clearance for pallet removal and easy traversal of obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional pallet jacks or dollies are used to transport communication cabinets, then the cabinets can be moved across floors, but the cabinets must be tilted which creates safety risks and requires special tools
Solution Approach 1:
Instead of tilting the cabinet to use a conventional pallet jack, the invention inverts the approach by using a lift system that raises the cabinet vertically while keeping it level. The lift assembly with crank mechanism elevates the cabinet body, allowing the pallet jack to safely remove the pallet from underneath without requiring the cabinet to be tilted, thereby eliminating tipping hazards and the need for special tools
Solution Approach 2:
The invention introduces a lift assembly as an intermediary mechanism between the communication cabinet and the pallet jack. This lift assembly includes a crank mechanism and lift arms that raise the cabinet body to a sufficient height, enabling the pallet jack to remove the pallet safely. The intermediary lift system mediates between the heavy cabinet and the transport mechanism, avoiding direct contact that would require tilting
2Quantity of substance
If the communication cabinet height increases to meet customer density requirements, then more equipment can be housed, but there is limited clearance above the cabinet to facilitate tilting
Solution Approach 1:
The invention inverts the traditional tilting approach by using vertical lifting instead. The lift assembly raises the cabinet body upward while maintaining its level orientation, eliminating the need for overhead clearance that would be required for tilting operations. This allows tall, dense cabinets to be transported without compromising maneuverability
Solution Approach 2:
The invention transitions from horizontal/angled movement (tilting) to vertical movement (lifting). By changing the dimension of the transport operation from lateral tilting to vertical elevation, the system accommodates taller cabinets with higher equipment density without being constrained by overhead clearance limitations
3Ease of operation
If integrated caster systems with small casters are used, then the cabinet can move across floors, but the casters cannot traverse obstacles like elevator gaps and thresholds
Solution Approach 1:
The invention changes the critical parameter of caster size from small (conventional) to large (greater than 4 inches). This parameter change enables the casters to traverse obstacles such as elevator gaps, thresholds, and elevation changes that would be impassable for smaller casters, while still maintaining the ability to move across floors
4Power
If conventional lifting solutions that lift from below are used, then the cabinet can be raised, but additional tools are required and the process is more complex
Solution Approach 1:
The invention merges the lifting function and transport function into a single integrated system. The lift assembly with crank mechanism combines the elevation capability with the caster-based transport system, eliminating the need for separate lifting equipment and tools. This unified approach reduces device complexity while maintaining full lifting capability

AI summary
A communication cabinet lift and transport system is provided including a lift and transport assembly having a support bar with at least one attachment bracket configured to be attached to a frame of the communication cabinet and a caster jack disposed near a either end of the support bar. Each caster jack including a bar mount configured to affix the caster jack to the support bar, a caster wheel disposed at an end of the caster jack, and a jack assembly configured to extend and retract the caster wheel relative to the bar mount. The communication cabinet lift and transport system is configured to raise and lower the communication cabinet relative to a surface, and translate the communication cabinet about the surface when the lift and transport system is in a raised position.
