Whether To Repair Or Replace An Old Elevator

Deciding whether or not to repair or replace an old elevator is an important decision that requires a number of factors to be considered.The following aspects can help to evaluate the most suitable choice:

1.Service Life of Elevators

The design life of an elevator is usually between 15 and 20 years.If the elevator has exceeded its design life, key components may deteriorate,operating efficiency decreases and safety risks increase.In this case, replacing the elevator is usually a wiser choice.If the elevator's service life has not yet reached the replacement criteria,but its performance has deteriorated, you may consider carrying out the necessary repairs and maintenance.

2.Maintenance History of the Elevator

The frequency of breakdowns and repair history of an elevator are important bases for judgment.If the elevator breaks down frequently,the cost of repairs continues to increase,and the core problem cannot be completely solved,it indicates that the elevator may have entered a high-maintenance period.Frequent repairs are not only costly,but may also interfere with normal use and reduce occupant or office worker satisfaction.In this case,replacing the elevator may be a more economical and reliable long-term solution.

3.Safety of the Elevator

The safety of the elevator is the most important consideration.If an elevator has serious safety hazards,such as aging electrical system,severe wear and tear of mechanical parts,unstable braking system, etc.,it should be prioritized for replacement.A new elevator that complies with the latest safety standards will not only eliminate potential problems,but also improve operational efficiency and user experience.

4.Common Problems of Old Elevators

During long-term operation,the following common problems may occur in old elevators:

● Frequent Floor Jamming and Interruption of Operation:Aging of the control system or wear and tear of the mechanical parts will lead to frequent stoppage of the elevator.

● Excessive Running Noise:Due to the wear and tear of guide rails,motors or pulleys,the elevator will produce obvious noise when running,which affects the user experience.

● Elevator Door Failure:Elevator doors may not open and close properly,willing to include door control system failure or sensor failure.

● Speed Instability and Vibration:Unevenness during acceleration and deceleration may be caused by problems with the traction system or aging clicks.

● Button and Display Failure:Internal control panels, displays and floor buttons may be damaged by aging wiring or frequent use.

● Excessive Energy Consumption and Inefficiency:Older elevators usually consume more electricity and have high operating costs,making it difficult to meet modern energy efficiency standards.

5.Modernization and Function Upgrade Demand

With the development of technology,modern elevators have been significantly upgraded in terms of performance,energy saving,intelligence and comfort.If you want to improve the operational efficiency of elevators,optimize the management system and improve the user experience through functional upgrades,replacing elevators may be the best choice.In addition,replacing elevators can increase the overall value and attractiveness of the building.

6.Cost-benefit Analysis

The initial cost of maintenance is usually low,but if maintenance is frequent,the long-term accumulated cost may far exceed the cost of replacing the elevator.In addition, older elevators consume more energy and their operating costs will increase.Replacing an elevator has a higher initial investment,but in the long run,it can save energy, reduce maintenance costs,and has higher economic benefits.

7.Government Regulations and Policy Support

Attention needs to be paid to local safety regulations and policies.If the government puts forward stricter requirements on the safety standards of elevators,or if there are relevant subsidy policies to support the renewal of elevators,replacing elevators may become a more attractive option.

Common Problems Of Old Elevators

There are many common problems that may occur during the long-term operation of old elevators,which will affect the efficiency,safety and riding experience of the elevator.The following is a detailed description of common problems of old elevators:

1.Mechanical System Failure

● Wear and Tear of Guide Rail:The length of guide rail will wear out after use,resulting in unstable operation of elevator,vibration and noise.

● Aging of Traction Machine:Aging of the traction machine will lead to unstable running speed of the elevator,and the phenomenon of sliding or stuck floors may occur.

● Brake System Failure:Worn out or ineffective brakes can cause serious safety hazards,such as the elevator being unable to stop in time or the risk of falling.

2.Electrical System Problems

● Control Panel Malfunction:Aging control system may lead to malfunctioning of buttons,incorrect display of floors,or even interruption of elevator operation.

● Aging Wires:Aging wires and circuits can lead to short-circuiting and tripping,which may cause fire and other safety accidents in serious cases.

● Failure of Sensing Device:Failure of door control sensor or light curtain will lead to the elevator door not being able to open and close normally,and even the accident of pinching people.

3.Door System Problems

● Door Cannot Open or Close Normally:Damaged door system will lead to frequent jamming of elevator door and passengers cannot enter or exit the elevator normally.

● Door Lock System Failure:Failure of the elevator door lock may lead to the door not being closed when the elevator is running,which is extremely dangerous.

4.Deterioration of operation performance

● Ordinary Stoppages and Failures:Due to the aging of the equipment,the operation of the elevator is frequently interrupted,seriously affecting the normal use.

● Slow Running:Insufficient power of traction machine or failure of control system will lead to slow running of the elevator.

● Inaccurate Floor Station:The elevator stopping level is not aligned with the floor,which affects the safety of passengers getting on and off.

5.Noise and Vibration Problems

● Increased Running Noise:The elevator generates large noise when running, which may be due to the serious wear and tear of the motor,pulleys and guide rails.

● Apparent Running Vibration:Imbalance of traction system and balancing device may lead to obvious vibration when the elevator is running,which reduces the riding comfort.

6.Energy Consumption and Economic Problems

● High Energy Consumption:The motor and control system of the old elevator are inefficient and consume large amount of electricity,resulting in high operation cost.

● Increased Maintenance Cost:Old elevators require frequent maintenance,and the maintenance cost may exceed the replacement cost after long-term accumulation.

7.Hidden Safety Dangers

● Failure of Emergency System:Emergency alarm and power failure rescue system may fail,affecting the safety of passengers in emergency situations.

● Missing Fire Protection Features:Some old elevators may not meet the latest fire protection and emergency evacuation standards.
