摘要： An elevator system capable of reducing the overall installation area of elevators in a building while ensuring the number of passengers in the elevator. The elevator system arranges first and second elevator cars in a single elevator hoistway, having, at a lower portion of each of the first and second elevator cars, respectively, a pair of undercar pulleys are positioned to turn ropes vertically on the outer sides of the first and second elevator cars and horizontally at the bottom, where the arranging direction of the pair of the under-car pulleys of the first elevator car intersects with the arranging direction of the pair of under-car pulleys of the second elevator car when projected onto a horizontal plane.

摘要： An elevator system (2) comprising a hoistway (4), an elevator car (6) and a counterweight (8) arranged to move within the hoistway (4). The system (2) further includes a first counterweight guide rail and a second counterweight guide rail arranged to guide the counterweight within the hoistway (4) and a guide rail bracket (32) which connects the first and second counterweight guide rails together. An elevator machine (10) is arranged to drive a tension member (14), which couples the elevator car (6) and counterweight together (8), to move the elevator car (6) within the hoistway (4). The system (2) further includes a friction reducing element (36) arranged on the guide rail bracket (32) such that if the tension member (14) moves towards the guide rail bracket (32) during operation of the elevator system (2), the tension member (14) contacts the friction reducing element (36).

摘要： A mounting frame for being displaced and fixed in a shaft has a main frame, a first primary fixing component for supporting the mounting frame on a first shaft wall of the shaft and a secondary fixing component for supporting the mounting frame on a second shaft wall of the shaft opposite the first shaft wall in a fixing direction during fixing of the mounting frame in the shaft. The first primary fixing component and the secondary fixing component are arranged on the main frame. The first primary fixing component and/or the main frame can assume a transport position and a working position. A change of the first primary fixing component and/or the main frame from its working position to its transport position leads to a reduction in an extension of the mounting frame in an extension direction that differs from the fixing direction.

摘要： An installation device used in an elevator shaft has a first carrier with first and second carrier ends, a support element pivotably arranged on the first carrier end, and a holding apparatus holding a displacement apparatus by which installation material can be displaced in the elevator shaft. When the installation device is in an installation position, the first carrier end is supported against a threshold of an elevator shaft door opening by the support element and the second carrier end is supported at least indirectly against a shaft wall that is opposite the door opening. The holding apparatus is arranged on an upper side of the installation device in the installation position such that the displacement apparatus is supported from above on the holding apparatus.
