Modernization Back to Services

Why modernize your elevator?

By allowing Davis & Newcomer to modernize your elevator, you can:

1. Eliminate high repair costs:

Worn out equipment is less dependable, less safe and more costly and time-consuming to troubleshoot. More often than not, delaying the process results in wasteful repair of obsolete components that cannot be absorbed in the needed modernization.

2. Ensure passenger safety & peace of mind:

Modernization brings new, more reliable equipment. More importantly, it brings state-of-the-art equipment whose technological advancements make for an installation that is safer and more readily maintained. It pays for itself.

3. Avoid costly downtime:

New components designed from new industry-wide advancements result in elevators that run. Equipment needing continual baby-sitting due to its marginal condition does not complement the needs of the building.

Components of A Typical Elevator Modernization

1. Controller & Fire Service Addition:

First and foremost, our controller is non-proprietary. We don't make controllers. We buy them from controller manufacturers who make that their only business. They design and assemble controllers using components and assemblies that are common in the industry. Nobody should hold the building owner hostage. Virginia Controls and Motion Controls Engineering, Inc., for example, supply us and countless others with first class equipment. This new controller system would be a solid state, microprocessor based, non-proprietary one, employing smoke detectors at the floors and machine room, working in concert with the new fire service I and II additions. The important functions of slow down, leveling, stopping, and direction of travel will come from a car top selector integrated into the system. Other possible components (different buildings have varying needs) in the elevator equipment room and hoistway could include:
bullet Furnish and install a new main line disconnect switch.
bullet Furnish and install a lockable disconnect switch to power the elevator car lights and alarm bell.
bullet Furnish and install a new approved stop switch with a new, G.F.I. duplex outlet.
bullet Furnish and install new wiring and electrical conduit/raceway to effect a complete system.

2. A.D.A. Modifications:

The Americans with Disabilities Act spells out accessibility standards for elevators. Listed are compliance items we have been making for a number of years now:
bullet New hall and car stations having location, style, height, and make up, in compliance with the Act (since existing stations, along with all their moving parts, are replaced, the maintenance profile of the installation is greatly enhanced).
bullet New emergency lighting and emergency alarm bell combine to provide:
- In-car illumination in the event of power failure.
- A solution for any trapped passenger(s).
- A readily operated, hands-free "phone" programmed to provide automatic access to and communication with designated assistance personnel.

3. Power Unit:

If hydraulic, replacement of the entire unit is generally recommended, as opposed to piecemeal (ala carte) replacement. All components would be new and it is less labor intensive than replacing items having different space and dimension characteristics. Most likely of submersible design, the motor, pump, and piping will be submersed. The unibody valve with built-in relief port is located at the top of the power unit for ready access. Purchase of a new power unit is priced on an OEM basis, compared with individually replaced components, priced at higher rates.

4. Infrared Curtain:

A replacement of the retractable car door safety edge & two beam electric eyes with an infrared curtain is an improvement and safety enhancement that would allow unlimited protection the entire door opening height, such that any obstruction would cause the doors to automatically retract. This system would replace the two beam electric eyes/safety edge that can cause serious injury.


5. Double Bottomed us a safety bulkhead. This safety bulkhead features an opening to limit the elevators descent should a failure occur in the double bottomed cylinder. The double bottom cylinder minimizes the risk from corrosion and leakage due to sealed PVC protection that encloses the entire cylinder.
