This line elevators is ideal for mid to high rise buildings where speed and efficient traffic flow are primary considerations. With speeds ranging from 0.75 m/s to 7 m/s, and capacities from 210 kg to 1890 kg, a variety of combinations are available to satisfy most traffic handling requirements. BF elevator geared elevator systems utilize micro-processor based dispatching and control systems to ensure smooth, trouble free operation. The mechanical advantage within the drive unit allows for the use of lower power motors, when compared to hydraulic elevators, for efficient elevator operation.
