SERVICE ON DEMAND ESCALATORS IN LAHORE

***DIRECT FROM THE MANUFACTURERS*** WE ARE NOT RESELLERS*** SERVICE ON DEMAND ESCALATORS Technology outline: An add-on feature on conventional escalator systems can be designed to detect passenger presence and stop when no activity has been detected for a period of time. The system will only be re-started automatically once a passenger has been detected. Since the operation of the escalator is determined by the presence or absence of passengers, it is known as "service-on-demand" (SOD) escalator. There are basically two types of SOD Controllers (a) Automatic start/stop control When an approaching passenger is detected, the escalator will start running and complete the traveling cycle. The escalator will stop after a period of time when no further passenger is detected. (b) Automatic two-speed control (crawl mode) Similar to the arrangement of auto on-off controlled escalator, the auto two-speed control SOD escalator will be actuated by the presence of passenger to run at rated speed. The auto two-speed controlled SOD escalator will run at a lower speed (crawling speed) when it detects no passenger for a set period of time. The crawling speed is usually set at about 0.2m/s, while the rated operating speed is 0.5m/s to 0.75m/s. Optical IR beam sensors is employed for sensing the presence of passenger. The detectors for monitoring the approaching passengers shall be integrated into the post installed at the entry of the escalator, or they can alternatively, be incorporated into the handrail entry of the escalator. How it can save energy? Service-on-demand control units are designed to detect the presence of passengers and either stop or slow down when no activity has been detected for a period of time. Hence, energy can be saved when the escalator is idle or operate at lower speed. How much energy may be saved The amount of saving depends on the type of buildings and passenger flow pattern. Based on statistical records from data available online (U.S. Electrical and Mechanical services Department), the energy saving of escalators integrated with service-on-demand control unit can be up to 52% and 14% for automatic start/stop and two-speed escalator respectively in an office building.
