The invention discloses a machine-room-less elevator which aims at the application scene that two machine-room-less elevators are adopted, the top space of the machine-room-less elevator is opened, and a first motor driving device, a first traction rope wheel, a second driving device and a second traction rope wheel are arranged in the opened top space and respectively occupy the common shaft wall extension section space. Or each occupies a common hoistway wall extension section space and a part of a counterpart hoistway extension section space. In this way, the cross sectional area space, occupied by the two motor driving devices and the traction rope wheel, of the lifting well can be reduced on the whole, and when one motor driving device breaks down, elevator maintenance personnel can run or move to approach the fault motor driving device through the other normal elevator; and maintenance or part replacement operation and the like are achieved, more operation convenience can be brought to elevator maintenance personnel, and the operation safety risk can be reduced.

    本发明公开了一种无机房电梯,针对采用两台无机房电梯的应用场景,其顶部空间打通,第一电机驱动装置及第一牵引绳轮、第二驱动装置及第二牵引绳轮均配置在打通的顶部空间,并各自占用共同的井道壁延伸段空间,或者各自占用共同的井道壁延伸段空间以及一部分对方井道延伸段空间。这样不但能从总体上减少两个电机驱动装置及牵引绳轮占用的升降井道横截面积空间,而且在其中一个电机驱动装置出现故障时,电梯维修人员可以通过另一台正常的电梯运行或移动接近故障电机驱动装置,并实现维护或零件更换的操作等,能给电梯维修人员带来较多操作便利及减少操作安全风险。
