Façade Lifting Jig With Pivot Linkage For Manual Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for lifting and installing façade elements in multi-storey buildings are time-consuming and labor-intensive, requiring significant manual effort and occupying valuable space on construction sites, with existing solutions being bulky and cumbersome.
Innovation Solution
A lifting jig with a base frame, lifting yoke, and link arrangement that allows for controlled, arc-shaped movement of the lifting yoke along guide profiles on the building, utilizing pivot arms and push rods with axially movable carriages to minimize manual labor and eliminate the need for powered actuators, enabling efficient engagement and lifting of façade elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gripping device is used to grip and move façade elements, then the façade elements can be lifted and installed, but the device becomes bulky and cumbersome requiring significant manual labor and time to move the gripping device into position
Solution Approach 1:
The gripping device is divided into multiple independent gripping elements that can move relative to each other along guide profiles. This segmentation allows each element to be positioned independently, reducing the bulkiness of the overall device and making it easier to maneuver into position while maintaining the capability to grip façade elements of various sizes.
Solution Approach 2:
The gripping device incorporates movable gripping elements that can dynamically adjust their position along the guide profiles during operation. This dynamic capability allows the device to transform from a compact configuration during transport to an extended configuration during gripping operations, reducing bulkiness without sacrificing gripping capability.
2Productivity
If conventional methods are used to lift and install façade elements, then the elements can be installed on the building, but the process is time-consuming and labor-intensive
Solution Approach 1:
The guide profiles are pre-installed on the building structure before façade element installation begins. This preliminary action allows the gripping device to be quickly positioned and operated without requiring complex alignment procedures during the actual installation process, significantly reducing the time required for unloading, transporting, and installing façade elements.
Solution Approach 2:
The guide profiles serve as an intermediary mechanism between the gripping device and the building structure. They provide a predefined path that guides the gripping device and façade elements into correct positions, eliminating the need for manual alignment and positioning operations that are time-consuming in conventional methods.
3Ease of operation
If façade elements are transported on pallets and lifted by cranes, then the elements can be moved to the building, but significant space on the construction site is occupied and a lot of manual labor is required
Solution Approach 1:
The gripping device with multiple movable gripping elements can handle various types and sizes of façade elements using the same basic mechanism. This universality eliminates the need for specialized equipment for different element types, reducing both manual labor requirements and the space needed for storing multiple different handling devices and pallets on the construction site.
