How do you install a new lift?
Installing a new elevator requires a comprehensive understanding of elevator systems and safety protocols. Installation of a new elevator needs professional expertise it's not a job one can learn theoretically it requires expert professionals. Here's a detailed step-by-step guide for technicians working in the elevator industry:-
1. Site Assessment:- Conduct a thorough site inspection to determine the ideal location for the elevator. Examine the available space, considering dimensions, load-bearing capacity, and accessibility for construction. Verify the electrical and structural integrity of the site. Ensure compliance with local building codes and regulations. Also, check working conditions for employees there is proper support available from building staff.
2. Design Review:- Review elevator system drawings and specifications to understand the project requirements. Confirm that the design aligns with safety standards and manufacturer guidelines. Inspect architectural plans, confirming the alignment of elevator specifications with the overall building design. Pay attention to door placements and alignment with floor openings.
3. Foundation Preparation:- Prepare the foundation according to the specifications provided by the manufacturer. Ensure the foundation is sturdy and meets structural requirements. Excavate the pit area, ensuring it meets the required depth and dimensions. Pour concrete for the foundation, allowing ample time for curing.
4. Hoistway Construction:- Build the hoistway structure based on the elevator dimensions. Follow precise measurements to accommodate the elevator components. Erect vertical beams and install horizontal supports for the hoistway structure. Use precise measurements to align the hoistway components accurately.
5. Pit Construction:- Construct the pit below the elevator for the buffer, safety gear, and other components. Verify that the pit depth adheres to the manufacturer's recommendations. Construct the pit walls using reinforced concrete. Install pit ladder and lighting for maintenance access.
6. Installation of Guide Rails:- Install guide rails in the hoistway for proper alignment and movement of the elevator car. Ensure accurate placement and secure fastening of the guide rails. Securely anchor guide rails to the hoistway structure. Confirm proper alignment of guide rails using a plumb line.
7. Elevator Car Assembly:- Attach the elevator car platform to the guide shoes on the guide rails. Assemble the elevator car, including the platform, walls, and safety features.
8. Counterweight Installation:- Install the counterweight system to facilitate smooth elevator movement. Verify the balance and alignment of the counterweight. Attach counterweight assemblies to the counterweight guide rails. Check the balance by ensuring the counterweight moves freely.
9. Installation of Control System:- Mount the motor and connect the control panel, ensuring all wiring is secure. Test the control system for accurate communication with the elevator components. Mount the control panel securely on a dedicated wall space. Connect wiring according to the manufacturer's diagrams and guidelines.
10. Safety System Setup:- Configure and test the safety features, including emergency brakes safety gear, over-speed governor, car top maintenance box, manual rescue system, buffer switch, pit emergency stop, COP & LOP working, final and slowing limits switch, ARD system, intercom, emergency alarm, fireman system working, Floor leveling, and door interlocks. Conduct a comprehensive safety inspection to meet regulatory standards. Configure emergency brakes and safety switches as per the provided instructions. Conduct a trial run to ensure the working of every safety.
11. Testing and Commissioning:- Perform a series of tests to ensure the elevator operates smoothly. Conduct load tests with the specified weight capacity. Gradually introduce loads during the load testing phase. Conduct safety gear or OSG tests, Fireman systems working, check automatic rescue devices working, etc. Conduct initial tests without passengers to check for any abnormal noises or movements.
12. Certification and Compliance:- Obtain certification from relevant regulatory bodies. Confirm compliance with the local building code and safety regulations.
13. Training:- Provide training to building staff or operators on the proper use and maintenance of the elevator. Train building staff on basic troubleshooting and emergency procedures. Provide documentation on the location of emergency tools and contact details for maintenance. Supply manuals and documentation for future reference.
14. Maintenance Plan:- Establish a routine maintenance schedule to ensure the elevator's ongoing performance and safety. Create a maintenance checklist covering regular inspections of critical components. Establish a schedule for routine maintenance tasks, including lubrication and sensor checks. Document all installations and maintenance activities for future reference.
Following these steps meticulously will contribute to a successful elevator installation while prioritizing safety and adherence to industry standards. By incorporating these basic details into each step, the elevator installation process becomes more comprehensive, ensuring a smoother and safer outcome.
