Elevators/Lifts

Two lift types used

Currently, two types of lifts are used in buildings: the hydraulic lift and electric lifts.

Hydraulic lift

The pistons and cylinders of a hydraulic lift are operated by a hydraulic power station. This system is typically suited for buildings that have up to 6 storeys. The machinery in this type of lift is generally smooth and quiet depending on whether you opt for a hydraulic underground, surface or telescopic surface cylinder lift.

Electric lift

The electric lift is the most commonly used model in today's buildings, especially in buildings with more than 6 floors. The electric lift is faster and more economical than the hydraulic lift. Its machinery is composed of several sub-functions. These include gearless lifts, which do not have a hoist. There are also lifts with a drum hoist and traction lifts, which entails a pulley connected to a geared motor.

How a lift works

To operate a lift, mechanical cables are used to raise or lower the car along with guides, while a counterweight ensures the car's safety. Various safety systems program the lift's speed, the landing doors opening on each floor, and a car blocking in the event of an incident.

The machinery of different lift models includes the drive mechanism and motor. It is usually stored in a dedicated technical area, which is either in the basement of the building, in the highest part, or directly in the shaft of the device.

Our vibro-acoustic solutions for lifts

There is a lot of machinery, high traction forces along with the guides, and the cabin's constant lifting and descending movements. As a result, lifts are prone to vibration and noise pollution. This is why Paulstra has developed a range of anti-vibration and acoustic solutions:

• Metal anti-vibration mounts,
• Elastomeric anti-vibration mounts,
• acoustic foams,
• Low-frequency mount.

In addition to improving user comfort, Paulstra's anti-vibration and acoustic solutions will extend the lift's service life. Constant vibration contributes to premature wear and tear of machinery components. Limiting its structure-borne vibration supports the equipment's service life.
