In the figure, 1 is a hoistway, and 2 has two car return cars 25 on the bottom surface. The car is suspended by main ropes 7 via the car return cars 25 and guided by car rails 3. The elevator car 5 in the hoistway 1 has a counterweight suspender 26 at the upper part thereof. The car 5 is suspended by the main rope 7 via the counterweight suspender 26 and guided by the counterweight rail 6. 1 is a counterweight that moves up and down, 8 is composed of a sheave 9 around which the main rope 7 is wound, and a motor section 10 that drives the sheave 9, and the rotating surface of the sheave 9 becomes horizontal and the sheave A hoisting machine located at the top of hoistway 1 so that 9 is below the motor section 10, 12 is a first directional pulley located at the top of hoistway 1, and 13 is a hoistway 2 is a second diverting pulley disposed at the top of FIG.
また、 主索 7はその一端を第 1の固定点 2 7に置き、 他端を第 2の固 定点 2 8に置く。 主索 7は、 第 1の固定点 2 7から、 釣り合いおもり 5 に配した釣り合いおもり吊車 2 6、 次いで昇降路 1の頂部に配置した第 1の方向転換プーリ 1 2、 次いで巻上機 8の綱車 9、 次いで昇降路 1の 頂部に配置した第 2の方向転換プーリ 1 3、 次いでかご 2の底面に配置 したかご下返し車 2 5を経て第 2の固定点 2 8に及ぶように掛けられて いる。 The main rope 7 has one end at a first fixed point 27 and the other end at a second fixed point 28. The main rope 7 is moved from the first fixed point 27 to the counterweight suspension wheel 26 arranged on the counterweight 5, then the first directional pulley 12 disposed at the top of the hoistway 1, and then to the hoisting machine 8. Sheave 9, then second diverting pulley 13 located on top of hoistway 1, then located on bottom of car 2 It is hung so as to reach the second fixed point 28 through the inverted car 25.
第 5図は第 4図における従来のエレベータ装置の昇降路 1の頂部を示 す断面図である。 図において、 ピボッ トアーム 2 9に常時接続されてい るとともに巻上機 8を配置したフレーム 3 0を示す。 ピボットアーム 2 9はピボッ ト軸 3 1によって、 破線で示す位置に回動可能となっている そのため、 従来のエレべ一夕装置は、 巻上機 8の取付け、 保守及び修理 作業を容易に行なうことができる点で有利であった。  FIG. 5 is a cross-sectional view showing the top of the hoistway 1 of the conventional elevator device in FIG. The figure shows a frame 30 which is always connected to a pivot arm 29 and on which a hoist 8 is arranged.
