Our UCMP OX-250U consists of detection subsystem (OX-240BU OSG, UKZ-01 control power box) and stopping subsystem . (OX-250 wire rope brake device). It uses UKZ-01 control power box to detect car door open or closing signal and provide the signal to OX-240BU OSG in time. The OSG then effectively mark or unmark car position according to car door open or closing state. When the elevator over speed upward or unintendedly moved under the open door state, the OSG OX- 240BU will decide and output triggering signals through the mechanical cable which connected with OX-250 wire rope brake device. Finally the stopping subsystem (OX-250 wire rope brake device) realizes car movement control through traction wire rope. This car unintended movement protection device combined the two functions of UCMP (unintended car movement protection) and ACOP (ascending over- speed protection).
