A method for introducing an elevator support into an elevator system includes a support brake device for controlling a drawing-in speed of the elevator support. The elevator support is wound on a support roller at a floor or in a machine room of a building. The elevator support is unwound from the roller and introduced into a shaft of the elevator system. The support brake device is arranged between the support roller and the shaft, and a drawing-in speed of the elevator support is adjusted by the support brake device. The support brake device contains a traction pulley for receiving the elevator support that is rotatably mounted in a support frame so that the elevator support can at least partly loop around the traction pulley. The traction pulley is braked by a pulley brake device, whereby the drawing-in speed can be controlled.

An arrangement for installing a set of elevator ropes includes one or more rope reels storing the set of elevator ropes, a rope wheel arrangement mounted on a fixed base comprising one or more rope wheels, a first rope guide detachably mounted in proximity of said one or more rope wheels of the rope wheel arrangement, and a second rope guide detachably mounted in proximity of said one or more rope wheels of the rope wheel arrangement. The ropes of the set of elevator ropes are arranged to pass from the one or more rope reels to said one or more rope wheels of the rope wheel arrangement via the first rope guide, which is arranged to guide the ropes to converge a rim of said one or more rope wheels at least substantially vertically, to turn around said one or more rope wheels, and to pass away from the one or more rope wheels via the second rope guide, which is arranged to guide the ropes to diverge from a rim of said one or more rope wheels at least substantially vertically. A method for installing a set of elevator ropes uses the disclosed arrangement.
