Embodiment Construction

[0011] figure 1 Represents a schematic and simplified side view of a traction sheave elevator without counterweight applicable to the solution of the invention, this elevator comprising at least an elevator traction machine 5 with a traction motor, a traction sheave 6, an elevator control system 8, and the elevator car 1 located in the car hanger 2, which moves in a substantially vertical direction along the guide rail 4 and is suspended on the traction rope 3. The first end of the traction rope 3 is fastened to the top of the car hanger 2, the traction rope 3 is extended from the top of the car hanger 2 and passed around the traction sheave 6, and then passed around the traction machine 5 from below The deflection pulley 1 and then go around the traction sheave 6 again from above, so that it goes around the deflection pulley 9 fixed at the bottom of the elevator shaft from below, and then continues to the bottom of the car hanger 2, the first pulley of the traction rope 3 Th...

Abstract

The invention relates to an elevator and an elevator brake, which elevator contains at least a hoisting machine (5) equipped with a traction sheave (6), a brake (10) affecting the rotational movement of the traction sheave and provided with at least one brake shoe (12) and a braking surface (11a), and hoisting ropes (3), which are fitted to move by means of the traction sheave (6) an elevator car (1) that moves along guide rails (4) . In an emergency braking situation when the elevator car (1) is moving in the upward direction, the brake shoe (12) of the brake (10) is arranged to move in the direction of rotation of the braking surface (11a) .

Description

technical field [0001] The invention relates to an elevator as stated in the preamble of claim 1 and to an elevator brake as stated in the preamble of claim 4 . Background technique [0002] Elevators are required by regulation to include emergency brakes, which are activated in unusual situations, such as during a power outage. The usual holding brake of the elevator is used, for example, as an emergency brake, which normally holds the elevator car in its position when the car is at a certain landing. The deceleration of the car under normal conditions is usually achieved by motor braking. When an elevator without counterweight is traveling upwards, the engagement of the emergency brake combined with the gravity of the earth can cause a significant deceleration of the elevator car that could endanger the safety of passengers. The emergency brake should thus not slow down the elevator car of an elevator without counterweight too effectively or at all when traveling upwards...
