Jumping Elevator Machine Room Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional jumping elevator systems require an elevator machine room to be arranged within the hoistway, which limits flexibility and increases construction costs, as the machine room must be lifted and rearranged as the building height increases.
Innovation Solution
The jumping elevator system separates the elevator machine room from the jumping platform, allowing it to be fixed outside the hoistway on a landing, eliminating the need for the machine room to jump or be lifted. This design simplifies the structure, reduces the lifting power required, and allows for easier relocation and reuse of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the elevator machine room is arranged within the hoistway and lifted with the jumping platform, then the elevator system can serve higher landings, but the structure becomes more complex and construction costs increase
Solution Approach 1:
The system divides the elevator components into two independent segments: the jumping platform (with guide rails and temporary working platform) that moves vertically to enable higher travel, and the elevator machine room that remains stationary outside the hoistway. This segmentation eliminates the complexity of lifting the entire machine room while still achieving extended traveling height.
Solution Approach 2:
The elevator machine room is extracted from the jumping platform and positioned independently outside the hoistway. This extraction removes the machine room from the lifting system, reducing structural complexity while maintaining the ability to serve higher landings through the jumping platform's vertical movement.
2Area of stationary object
If the elevator machine room is arranged within the hoistway, then the elevator system can be compact, but the lifting power required increases
Solution Approach 1:
The elevator machine room is extracted from the jumping platform and positioned independently outside the hoistway. This extraction removes the machine room from the lifting system, significantly reducing the lifting power required while the compact hoistway space is optimized for guide rails and temporary working platform only.
3Length of moving object
If guide rails need to be extended and newly extended guide rails need to be positioned and mounted on the hoistway, then the traveling height can be increased, but the operation becomes more complex and time-consuming
Solution Approach 1:
The guide rails are pre-assembled in sections outside the hoistway before the jumping operation. The temporary working platform is positioned in advance to facilitate this pre-assembly work. This preliminary preparation simplifies the on-site installation process and reduces the time required during actual jumping operations.
Solution Approach 2:
The temporary working platform serves as an intermediary structure that provides access and support for installing guide rails at elevated positions. This intermediary platform simplifies the complex task of positioning and mounting guide rails by providing a stable working surface and safe access points.
4Device complexity
If the machine room is fixed outside the hoistway, then construction costs are reduced and operations are simplified, but the elevator system cannot serve higher landings
Solution Approach 1:
The system segments the elevator into independent components: the stationary machine room outside the hoistway and the movable jumping platform with guide rails inside. This segmentation allows the machine room to remain fixed and simple while the jumping platform extends the traveling height through vertical movement.
Solution Approach 2:
The jumping platform and guide rails are designed as dynamic components that can move vertically to different positions, enabling the elevator to serve higher landings. This dynamic capability is achieved without moving the machine room, maintaining structural simplicity while extending travel range.

AI summary
The present disclosure relates to a jumping elevator system and a jumping method used in construction process of building. Embodiments of the jumping method comprise: preliminarily positioning and mounting, by means of a temporary working platform (160) at a first height, a guide rail (930) on the hoistway (910) substantially corresponding to the first height; removing the temporary working platform from the position, corresponding to the first height, of the hoistway; lifting, by use of a lifting assembly, a jumping platform (150) from a second height to a third height, wherein the third height is greater than the second height and less than or equal to the first height; and lifting, by use of the lifting assembly, the elevator car (110) to extend its traveling distance in the hoistway, and operating, during lifting of the elevator car, on the top of the elevator car for reinforcing the mount of the guide rail.
