Elevator Drive Mounting Slide Using Shaft Head Ceiling Lift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting elevator drives in shaft heads face challenges with limited space between guide rails and the shaft wall, leading to cumbersome and expensive solutions, including the need for additional brackets and limited lifting height, which compromise safety and efficiency.
Innovation Solution
A method using a lifting device with a mounting slide consisting of a counterweight and bracket to lift the elevator drive to the desired height above the guide rails, allowing manual positioning and secure attachment, utilizing the space intended for the elevator car to maximize horizontal dimensions and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the lifting device is mounted on the guide rails near the shaft head, then the shaft space for the elevator car is preserved, but the maximum lifting height is significantly below the desired position and additional brackets are required
Solution Approach 1:
The lifting device is mounted on the shaft head ceiling (vertical dimension) rather than on the guide rails (horizontal dimension), enabling the elevator drive to be lifted directly to the desired mounting position above the guide rails without requiring additional vertical clearance or intermediate brackets
2Ease of operation
If the lifting device is set up in the shaft pit with rope diversion via pulley, then the installation space in the shaft head is solved, but the need for brackets and limited lifting height problems persist
Solution Approach 1:
The lifting device is extracted from the shaft pit location and repositioned to mount directly on the shaft head ceiling, eliminating the need for complex rope diversion systems and intermediate brackets while maintaining full access to the mounting area
3Area of stationary object
If the elevator drive is installed as close as possible to the shaft head ceiling, then space in the shaft head is maximized, but the lifting operation becomes dangerous due to unfavorable inclined lifting
Solution Approach 1:
The lifting device is positioned on the shaft head ceiling directly above the mounting position, creating a vertical lifting path that maintains gravitational equipotential alignment and eliminates dangerous inclined lifting conditions
4Area of stationary object
If the lifting device is mounted on the side facing away from the elevator car, then the shaft space is preserved, but the rope runs the risk of getting in the way of correct positioning
Solution Approach 1:
The lifting device is positioned as an intermediary on the shaft head ceiling, centrally located above the guide rails, which allows the lifting rope to run vertically without interfering with the horizontal positioning operations of the elevator drive

Function Achieved in This Case
This approach enables easy, safe, and efficient mounting of elevator drives with increased space for the elevator car, improving work safety and simplifying the installation process by eliminating the need for additional clearance and reducing the risk of tilting or entanglement during lifting.
Implementation Method 1
the elevator drive is lifted by means of a lifting device on a mounting slide - consisting of a mounting bracket and a counterweight - to the height of the intended mounting position
