Abstract

PURPOSE:To economize space, secure the maintenance inspection work space, and reduce the number of necessary parts by installing a pulse generator on the upper part of a longitudinal shaft which is supported on a stand and rotates together with a pulley according to the speed of an elevator cage. CONSTITUTION:A pulse generator 33 is installed on the top edge of the horizontal upper part of a nearly U-figure-shaped installation plate 32 which is screw jointed to the upper part of a stand 15, while penetrating through the top part of a longitudinal shaft 20. When an elevator cage shifts, a sheave 11 is turned by a rope 12, and the longitudinal shaft 20 is turned by the transmission of a bevel gears 17 and 21, and pulse signals are sent into a microcomputer from the pulse generator 33, and the position of the elevator cage is detected by the calculation processing. Accordingly, a slit disc, supporting member, housing, and a pulse counter in the conventional method can be omitted.
