Self-Climbing Elevator Arrangement for High-Rise Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art jump-lift systems for high-rise building construction are complex, expensive, and require significant space, limiting the number of floors that can be serviced by the elevator and necessitating intermediate platforms to prevent material fall, which complicates the construction process.
Innovation Solution
A self-climbing elevator arrangement that integrates key functions, eliminates the need for intermediate crash decks, and uses guide rails for climbing, allowing the elevator to operate with minimal vertical space, enabling early installation and reuse across different construction sites, without requiring special interfaces in the shaft walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If prior art jump-lift systems are used to increase hoisting height, then the elevator can reach higher floors, but the system becomes more complex and requires special interfaces in the shaft walls
Solution Approach 1:
The elevator machine room is equipped with self-climbing means that enable it to climb automatically along the guide rails in the shaft without external assistance. This self-service capability eliminates the need for complex intermediate platforms and special shaft interfaces, allowing the system to achieve greater hoisting heights while reducing overall system complexity
Solution Approach 2:
The system transitions from a static installation requiring pre-built shaft interfaces to a dynamic self-climbing mechanism that adapts to the shaft structure. The machine room can move dynamically along the guide rails, eliminating the need for fixed special interfaces at each level
2Length of stationary object
If prior art jump-lift systems are used, then the elevator can service high floors, but intermediate platforms (crash decks) are required to prevent material fall
Solution Approach 1:
The harmful intermediate platforms (crash decks) are completely removed from the system. Instead of requiring these intermediate structures to prevent material fall, the invention uses a containment approach where the elevator car itself and its loading mechanism prevent material from falling into the shaft
Solution Approach 2:
A intermediate container or loading mechanism is introduced between the elevator car and the shaft environment. This intermediary structure prevents material from falling into the shaft while eliminating the need for fixed intermediate platforms, allowing the elevator to service high floors without the complexity of crash decks
3Length of stationary object
If prior art jump-lift systems are used, then the elevator can reach higher floors, but significant vertical space is required above the machine room deck
Solution Approach 1:
The machine room uses its own onboard climbing means to ascend along the guide rails, eliminating the need for extensive vertical clearance above it. This self-service climbing capability allows the machine room to reach higher floors without requiring significant vertical space above its position, as it climbs rather than being hoisted from below
4Length of stationary object
If prior art jump-lift systems are used, then the elevator can service high floors, but the number of floors that cannot be serviced increases
Solution Approach 1:
The system changes the parameter of machine room positioning by enabling continuous or near-continuous climbing along the guide rails rather than being restricted to fixed jump levels. This parameter change allows the elevator to service floors much closer to the top of the shaft, minimizing the number of unserviced floors and improving overall productivity

AI summary
The arrangement comprises a self-climbing installation platform comprising two consecutive decks, a machine room deck suspended from the installation platform and an elevator car suspended from the machine room deck. Each deck, the machine room deck and the car are supported movably with guide means on guide rails and locked and unlocked with locking means to the guide rails and/or to guide rail fixing means. Lifting means powered by a power source move the two decks in relation to each other. The installation platform climbs stepwise along the guide rails by alternatingly locking and unlocking the lower deck and the upper deck to the guide rails and/or to the guide rail fixing means and thereafter raising the unlocked deck.
