Elevator Modernizations on the Rise

An overview of several vertical-transportation modernizations delivered by ETA Melco

The vertical-transportation industry has been abuzz with modernization across the world, especially in markets where elevators have been in use for more than 20 years. The U.A.E. (specifically, Dubai, Abu Dhabi and Sharjah) is a relatively new market, having a limited number of elevators, primarily installed during the late 1970s. ETA Melco is one of the earlier companies to have installed Mitsubishi elevators and escalators for prominent projects in the country. 

The U.A.E.’s growth has forced the world to turn its attention toward its fast-paced metro cities. The first step toward modernization is a process called the “pre-modernization” evaluation. Some of the factors focused on prior to suggesting modernizations are sound, vibration, waiting time, roundtrip time, acceleration, deceleration, door-opening time, etc.

Increasing tenant demands for improved reliability escalates the pressure on facility-management executives. For most riders, a well-serving elevator is always a “faster” elevator. However, the industry knows it is more important to focus on improved destination dispatch, shorter wait times and optimal roundtrip times, etc. Aesthetics are also important to end users. An aesthetically pleasing elevator is not the only expectation of building owners. They also expect fewer breakdowns, more significant safety features, optimal power factors (low energy consumption), reliability and shorter maintenance downtime.

The industry has been particularly focused on code requirements for fire alarms, building-management systems, entrapment rescue procedures, compatibility between older power generators and the latest models of solid-state drives, and local fire-brigade procedures for carrying out pre-modernization evaluations.

ETA Melco has completed many significant modernization projects in its 21 operating countries. Details of a few recently completed and in-progress projects follow.
