PURPOSE:To lower the landing running speed of a cage before landing to the same speed as that of a rope type by taking the speed of a plunger into a speed control system, and constituting a speed control system strong to a disturbance. CONSTITUTION:When a cage approaches a target floor, the cage is run at a rated speed up to a time t4 when the output of a cage position detecting circuit regularly detecting the position of the cage becomes a determined value by the output pulse 11a of an encoder 11, deceleration is then started, and the speed is lowered close to a stop position, and rendered to a landing speed at a time t5. Then, at a time t6 when a stop position signal 6a from an inductive type position detector 6 is outputted, an operation instructing relay 43 is off, and the cage is stopped. At a time t8, an electromagnetic brake 16 is closed, and at a time t9, a starting compensation instructing output relay 21 is off and the cage operation is terminated. |
