ELEVATOR WARRANTY AND MAINTENANCE

Elevator equipment warranty policy

Elevator equipment warranty is one of the crucial factors ensuring the quality and durability of the elevator system throughout its lifespan. The company is committed to providing all elevator equipment that is 100% new, unused, and fully meets the technical specifications and characteristics stated in the contract. This gives customers peace of mind regarding the origin and quality of the product.

During the inspection, acceptance testing, or installation process, if any equipment is found to be technically unsuitable or of substandard quality, the elevator company will be responsible for timely replacement or repair. All costs related to repair or replacement will be borne by the company, ensuring maximum protection of customer rights.

Equipment maintenance not only helps maintain the stable operation of elevators but also minimizes the risk of damage, ensuring user safety. Components such as traction machines, control cabinets, traction cables, magnetic brakes, and ARD rescue systems are thoroughly inspected and warranted according to technical standards .

Elevator maintenance

The free warranty period for elevators is 24 months from the date of acceptance and handover of the project for use. During this period, the elevator company commits to fully comply with all regulations regarding project warranties according to current regulations.

Elevator maintenance

Elevator maintenance is essential to maintain operational efficiency and ensure user safety. During the 24-month warranty period, the company performs scheduled maintenance every two months according to established technical maintenance procedures.

Each time maintenance or repair is performed, the user's representative will sign the work order, ensuring transparency and tracking the maintenance history of each piece of equipment. This helps to detect early signs of wear and tear or damage so that timely action can be taken, avoiding disruptions to elevator operation.

After the warranty period expires, the company and the customer will sign a comprehensive maintenance contract with flexible terms ranging from 1 year, 5 years to 10 years. Spare parts and components are always kept in stock to ensure prompt maintenance and warranty service.

Scheduled maintenance procedure

• Inspect the machine room and elevator shaft environment: Ensure there is no dust, moisture, or obstructions that could affect elevator operation.
• Inspect the mechanical components: The traction machine, guide pulleys, magnetic brakes, guide shoes, rails, and rail supports are inspected, calibrated, and properly lubricated.
• Check the electrical and control systems: Control cabinets, switches, power supply boxes, ARD emergency response units, and speed limiters are checked for stable operation.
• Cabin and door inspection: Doors, door motors, cabin control panel, cabin lights, fan, display system, and emergency bell are inspected and maintained.
• Safety checks: Safety switches, door interlocks, limit switches, safety devices, and rescue components are thoroughly inspected.
• Record keeping and reporting: All maintenance work is documented in detail on the maintenance sheet, including equipment condition and items serviced, repaired, or replaced.

Training on safe and efficient elevator use.

Alongside warranty and maintenance services, elevator user training plays a crucial role in ensuring safety and extending equipment lifespan. After acceptance and handover, the elevator company organizes training courses for users with the following basic content:

• Safety principles for elevator construction and operation: These principles help users understand regulations and accident prevention measures.

In addition, the company provides complete technical documents, drawings, equipment catalogs, elevator inspection reports, and user and maintenance manuals for customers to easily access and manage.

Detailed elevator maintenance form

An elevator maintenance log is an important tool for documenting the condition and work performed during maintenance. A standard maintenance log includes the following items for inspection:

• Engine room: Engine room environment, switches, power supply box, traction machine, magnetic brake, guide pulley, control cabinet, encoder head, speed limiter, ARD rescue unit, engine oil, engine room beam.
• Cabin roof: Cabin frame, cabin roof pulley, cabin guide shoes.
