Elevators are usually taken for granted, but they need regular maintenance to work properly. A well maintained elevator usually lasts for about 25 years, but some parts may need to be replaced regularly.
Even if the elevator is well maintained, it may eventually need to be overhauled or replaced. Modifications to existing systems are referred to as modernization, and can be complete or partial. If the new track is added to the existing elevator, or a new elevator is installed from the beginning, the project is considered a new construction.
It's better to be proactive, not passive, but responsive. Elevators should be inspected by certified professionals every year.
In the city of New York, the building elevator Department oversees all elevator replacement projects. The department reviews proposals, problem permits, safety inspections and inspections.
If the components are no longer available, if the equipment is far beyond their life expectancy, or if the elevator meets the requirements of the specification of the repair, so that the replacement of the elevator is more cost-effective, you may need to replace the elevator.
The old equipment is closed, and the way of disassembly and disassembly varies with the size and scope of the building and its elevator. In most cases, the hoistway is fixed to prevent any accidental movement. Then remove the controller, drive the machine and door equipment. In some cases, it is necessary to clear the walls or ceiling of the computer room so as to get into the old equipment. Many buildings have a loophole in the machine room, so workers can remove old equipment and bring up new equipment on lower floors. The crane can also be positioned on the roof of the building to help the construction.
When the new elevator is installed, the controller is behind. It wired the elevator in a temporary position so that the worker could move it to the shaft manually. Then the elevator is fully connected to the new controller for automatic use. The elevator must be tested by the inspector and any relevant institution under full load. The elevator is ready to be used by passengers after receiving the boarding pass.
The cost of modernizing or replacing elevators may vary greatly. It depends on a number of factors, including the size of the building, its location, the equipment, and the choice of the cab.
If elevator maintenance is required, the building administrative staff and board members need to notify the residents ahead of schedule and update with the progress of the project. Some construction managers choose acceleration arrangements to minimize damage.
