Abstract: An elevator system for traveling on a rail attached to the outside of a high-rise building. One elevator has a telescopic arm attached for reaching any position on or above the building. The telescopic arm consists of two parts, which are interconnected with a pivoting mechanism. The crane portion has a rotating mechanism and a pivoting mechanism for supporting one end of the arm. A functional compartment is provided in a building, a sliding frame is mounted in this compartment, connected with jack mechanisms; with the help of these mechanisms the sliding frame can slide beyond the outer limits of the building and back. Smooth and safe sliding of the frame is ensured by its supporting wheels sliding in guiding rails mounted in the surfaces of the functional compartment. The sliding frame is equipped in its front part, with a receiving panel with the right and left “pocket” guiders on it.
