Abstract

An elevator, preferably an elevator without machine room, in which the hoisting machine (10) engages the hoisting ropes (3) by means of a traction sheave (11), the elevator car (1) being at least partially supported by the hoisting ropes serving as a means of moving the elevator car (1). The elevator car is suspended on the hoisting ropes (3) by means of at least one diverting pulley (13,14) from whose rim the hoisting ropes go upwards from both sides and at least one diverting pulley (7,5) from whose rim the hoisting ropes go downwards from both sides of the diverting pulley. The traction sheave (11) engages the rope portion between these diverting pulleys (13,5).
