Traction Lifts versus Hydraulic Lifts
Did you know that the first elevator shaft was installed in the Cooper Union Foundation building, New York, four years before the elevator was invented? Designed and built by Elisha Otis, the first commercial passenger lift opened new doors in the development of buildings making today’s skyscrapers possible. Since their initial invention, lifts are now a common consideration in most public buildings and even homes. We take a look at two of the most common types, traction and hydraulic and you should consider both before installing.
Traction lifts are the most common type with lift itself pulled up through the lift shaft by rolling steel ropes via a pulley system. The weight of the lift is balanced by a counterweight. With ongoing developments, some traction lifts now feature flat steel belts instead of ropes; these are lighter and feature a high-friction coating meaning no oil or lubricant is required.
Benefits of a traction lift:
Uses less energy than a hydraulic lift due to the use of a counterweight
Modern traction lifts tend to be quicker than hydraulic lifts
Traction lifts provide a smooth ride
During the 1980’s, hydraulic lifts accounted for around 80% of installations in the UK and are still considered the best choice for a lot of new lift installations. Hydraulic lifts work with a system that contains two pistons connected by a tube. A pumping system with fluid is used and moves the lift up.
Benefits of a hydraulic lift:
Often cheaper to install than a traction lift
Take up less space with the hoistway alone requiring about 10% less room
More effective for use to transport heavy loads
