Access for allSafety and comfort of an elevator go hand in handwith smooth operation and stopping accuracy.Eliminating trip hazards between car and landingfloor is not only necessary for elderly people, peoplewith handicaps or passengers pushing a baby buggyor shopping cart, but the new European GuidelineEN 81-80 (SNEL Safety Norm for Existing Lifts)explicitly requires accessibility by avoiding any riskof stumbling or falling.

Economically and ecologically soundBeyond comfort and safety for passengers, operatorsand owners of buildings demand an economical andecological operation of their elevators. As the liftsconsume a significant amount of energy in a build-ing, responsible energy usage helps to cut oper-ational costs. With a Schindler DR VCB or DR VAByou put these demands into practice. Successfully.

Driving with comfortSchindler state-of-the-art frequency convertersdeliver full and precise control of velocity and motorpower from zero to full speed. This not only leadsto comfortable acceleration and deceleration butalso to precise and safe levelling accuracy. Thepassengers benefit from a comfortable ride with norisk of tripping when stepping in or out of the car.

On time arrivalA modernised elevator also increases the level ofavailability. Thanks to shorter travel times, optimizedtiming and driving cycle, the elevator is alwaysready when you need it.
