Abstract (en)
An elevator arrangement (1) comprising a cabin (3) and a counterweight (5) being displaceable in traveling directions (4, 6) within an elevator shaft (11), an elevator controller (13) for controlling motions of the cabin (3) and the counterweight (5), and a safety monitoring device (15) is proposed. The safety monitoring device (15) comprises a 2D-sensor (19) for contactless supervising a supervision plane (21) extending away from the 2D-sensor (19) in an extension direction parallel to the traveling directions and for determining a distance (d) between the 2D-sensor (19) and an object (28) located within the supervision plane (21). Therein, the safety monitoring device (15) is adapted for initiating safety measures upon detecting that the determined distance (d) is smaller than a predetermined allowable minimum distance (d m ). The safety monitoring device (15) may be a relatively simple device such as a scanning laser distance measurement sensor (20). By suitably arranging its supervision plane (21) for example underneath the counterweight (5), serious collisions between the counterweight (5) and for example an extremity of a technician (23) may be avoided.
