HYDRAULIC ELEVATORS: TYPES & BENEFITS
The mechanics of the high-rise elevator systems mentioned above consist of cables and sheaves, also known as pulleys, which run between the elevator cab and elevator machine room, counterweights that balance the elevator cab, the electric motor, and the braking system. These mechanical elevators are also referred to as “traction elevators.” Traction elevators are recommended for NYC skyscrapers due to their energy efficiency, smooth ride, and high-speeds that whisk passengers to their desired floor, faster than its passengers can ‘name the tune’ of the elevator ‘muzak’ played inside the cab.To get more news about elevator counterweight, you can visit cntrueplate official website.
However, a traction elevator whisking building residents, tenants, and passengers to their destination in seconds may be superfluous if one owns or manages a three-story garden-style apartment or condo, or a small office building less than seven stories high. Hydraulic elevators would better serve the need of these buildings.
The difference between the traction and hydraulic lifts are distinct. Traction elevators are composed of an electric motor moving the heavy-duty metal cables and pulleys and counterweights. In contrast, hydraulic elevators use electric motors to drive a hydraulic jack of fluid-filled pistons inside a cylinder to lift the elevator cab. What hydraulic jacks lack in high-speed energy efficiency, moving passengers at an approximate speed of 150 feet per minute, is made up for with its cost-efficiency. Elevators with a hydraulic jack take less time and expense to install, requires less maintenance cost, and takes up less space within buildings of low or mid-rise height. Such elevators are, however, a bit noisier than the traction elevator. |
