Server Rack Lift Attachment for Low-Clearance Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual movement of mobile server racks in data centers is difficult due to their large size and weight, and fork lifts cannot be used because of low ground clearance, making it challenging to maneuver and relocate equipment efficiently.
Innovation Solution
A lift attachment that attaches to a lift truck, featuring sidewalls, lift plates, and a connector to engage with the lifting mechanism, allowing for the attachment to be used with both powered and autonomous lift trucks, enabling the lifting and transport of server racks with low ground clearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual pushing and pulling is used to move server racks, then no special equipment is needed, but the movement is difficult and inefficient due to large size and weight
Solution Approach 1:
The patent introduces a forklift attachment as an intermediary device that connects the forklift to the server rack. This attachment includes fork receptacles that receive the forklift forks and a lifting mechanism with plates that engage the rack perimeter, enabling mechanical assistance for moving heavy racks without direct manual handling.
2Force
If fork lifts are used to move server racks, then lifting capability is provided, but they cannot be used due to low ground clearance
Solution Approach 1:
The patent solves the ground clearance problem by changing the dimensional approach - instead of lifting from the bottom (requiring vertical clearance), the attachment engages the rack from the sides and top. The fork receptacles receive forks horizontally, and the lifting plates engage the rack perimeter from above, eliminating the need for bottom clearance.
Solution Approach 2:
The forklift attachment serves as an intermediary that adapts the forklift's lifting capability to work with low ground clearance racks. The attachment includes components specifically designed to engage racks regardless of their bottom clearance, making forklifts compatible with a broader range of rack types.
3Productivity
If manual repositioning of servers and networking equipment is performed, then no additional equipment is required, but the process is time-consuming and labor-intensive
Solution Approach 1:
The forklift attachment acts as an intermediary tool that enables efficient relocation of entire rack units without manually moving individual servers and networking equipment. The attachment securely engages the rack perimeter and allows the entire assembly to be lifted and repositioned as one unit, dramatically reducing relocation time and labor requirements.

AI summary
A lift attachment includes a first sidewall and a second sidewall, each of the first sidewall and the second sidewall being disposed in an upright position and substantially parallel to one another. The first sidewall and the second sidewall are spaced apart from one another and include inner surfaces that face one another and define a bay therebetween. The lift attachment further includes at least one lift plate having a ledge that extends from a bottom of the first sidewall and the second sidewall. The ledge includes an inner edge that defines an opening through a bottom of the lift attachment and through the entrance of the lift attachment. A connector of the lift attachment is configured to connect with a lifting mechanism of a lift truck such that the lift attachment moves up or down with the lifting mechanism.
