Converting gravity into electricity has been an important strategy for those seeking to improve the energy efficiency of lift installations.
In 2009 EMSTF replaced the lifts at the Sheung Shui Police Married Quarters with regenerative lifts, which convert the energy generated from the lift motor driven by gravity into electricity for other uses. Compared to conventional lifts, regenerative lifts are 20-30% more energy efficient.
Another new feature is the use of coated steel belts rather than traditional suspension ropes for more even distribution of pressure and longer service life. The belts' condition is monitored around the clock to ensure safety. Because there is less vibration during acceleration and deceleration, regenerative lifts offer a more comfortable ride.
The Sheung Shui Police Married Quarters is the first government quarters to be installed with regenerative lifts. This energy efficient installation provides a green lift option for client departments to consider applying in their venues.
