Elevator Guide Rail Installation Hoist and Lever Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of elevator guide rails is labor-intensive and time-consuming, particularly in modern high-rise buildings, as existing methods require manual handling and alignment of guide rail elements, which prolongs the process.
Innovation Solution
A method involving a first hoist with a hook device and a lever device to lift and align guide rail elements, allowing controlled installation and attachment to the shaft walls, combined with a transport platform for connecting and securing the elements, either manually or automatically by a robot, to streamline the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual handling and alignment of guide rail elements is used, then installation precision can be maintained, but installation time and labor intensity increase significantly
Solution Approach 1:
The guide rail elements are pre-equipped with alignment features (alignment pins, alignment grooves, or alignment marks) during manufacturing. This preliminary preparation enables rapid and accurate alignment during installation without requiring time-consuming manual measurement and adjustment, thus resolving the contradiction between precision and installation time
Solution Approach 2:
Alignment aids such as alignment pins, alignment grooves, or alignment marks serve as intermediary elements that facilitate precise positioning of guide rail elements. These intermediaries guide the installation process, ensuring accuracy while reducing the time and skill required for manual alignment
2Length of stationary object
If multiple guide rail elements are connected end-on-end, then the required height coverage in high-rise buildings is achieved, but the complexity of installation and alignment increases
Solution Approach 1:
The guide rail system is divided into standardized modular elements of fixed lengths. Each element is designed with consistent connection interfaces and alignment features, allowing repetitive installation patterns. This segmentation reduces installation complexity compared to custom-length rails, as workers can systematically connect standardized units to achieve any required height
Solution Approach 2:
Connection plates and fastening mechanisms are pre-positioned or pre-configured on the guide rail elements during manufacturing. This preliminary preparation eliminates the need for complex on-site measurements and custom fabrication, allowing workers to simply connect pre-configured modules, thereby reducing installation complexity while achieving required heights

AI summary
The method comprises installing a lowermost first section of guide rail elements (25), moving a guide rail element upwards along a row of already installed guide rail elements with a transport apparatus (600), connecting the guide rail element to an upper end of the row of already installed guide rail elements and attaching the guide rail element to a wall (21) of the shaft from a transport platform (500), moving the transport apparatus downwards along the row of already installed guide rails in order to fetch a new guide rail element.
