Shaft Opening Fixing Device for Elevator Installation Frame Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transporting and introducing an installation frame into an elevator shaft is complex due to the frame's dimensions and weight, and the lack of a solid floor or temporary platform at the shaft opening.
Innovation Solution
A mobile transport device with a base frame and a bearing frame that supports the installation frame, allowing horizontal movement through the shaft opening, and a fixing device to secure the transport device to the shaft opening, preventing tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the installation frame is transported and introduced into the shaft manually, then the installation frame can be positioned in the shaft, but the process becomes complex and dangerous due to the frame's dimensions and weight
Solution Approach 1:
The transport device is divided into two separate frames: a base frame that remains outside the shaft and a bearing frame that carries the installation frame into the shaft. This segmentation allows each frame to perform its specific function independently, simplifying the overall introduction process while handling the heavy installation frame safely
Solution Approach 2:
The bearing frame acts as an intermediary device between the base frame and the installation frame. It facilitates the transfer of the heavy installation frame into the shaft by providing a movable platform that can be pushed through the shaft opening while the installation frame remains supported throughout the process
2Ease of operation
If the installation frame is pushed through the shaft opening, then the frame can be introduced into the shaft, but the transport device may tilt during the process
Solution Approach 1:
The fixing device provides counterbalancing support to prevent the base frame from tilting when the bearing frame is pushed into the shaft. By securing the base frame to the shaft opening structure, the fixing device counteracts the uneven weight distribution and forces generated during the introduction process
Solution Approach 2:
The base frame is fixed to the shaft opening using the fixing device before the bearing frame is pushed into the shaft. This preliminary action ensures that the base frame is securely anchored in advance, preventing tilting during the subsequent introduction of the bearing frame and installation frame

AI summary
A mobile transport device and a method for introducing an installation frame into a shaft, in particular an elevator shaft, are used for transporting an installation frame and for introducing the installation frame into the shaft. The installation frame has a base frame and a bearing frame on which the installation frame is supported from above. The transport device additionally has a fixing device arranged on the base frame for fixing the base frame to a shaft opening of a shaft wall of the shaft and for preventing the transport device from tilting. The bearing frame is supported by the base frame and is movable in the horizontal direction relative to the base frame such that, when the base frame is arranged outside of the shaft, the bearing frame, and thus also the installation frame, can be moved into the shaft from outside the shaft through the shaft opening.
