摘要： A braking system for an elevator includes an electromagnetic brake operably connected to an elevator car. A control circuit is operably connected to the electromagnetic brake and includes a switching mechanism to selectively modify a rate of engagement of the electromagnetic brake to selectively modify deceleration of the elevator car. A method of engaging an electromagnetic brake for an elevator system includes detecting one or more operational characteristics of the elevator system and selecting a first position or a second position of a switching mechanism disposed at a brake control circuit depending on the sensed operational characteristics. Electrical current is directed through one or more components of the brake control circuit, depending on the position of the switching mechanism, to determine a rate of engagement of the electromagnetic brake. A flow of electrical current through the brake control circuit is stopped, thereby causing engagement of the electromagnetic brake.

摘要： A machine assembly for use in an elevator system is provided including a drive sheave (52) configured to rotate about a first axis of rotation (R). A first roller shaft (54) is configured to rotate about a second axis of rotation (S) substantially parallel to the first axis of rotation. Rotation of the first roller shaft about the second axis of rotation is configured to rotate the drive sheave about the first axis of rotation. A first motor is operably coupled to the first roller shaft and is configured to rotate the first roller shaft about the second axis of rotation.

摘要： The present invention relates to a mechanical device for reducing the energy absorbed by an electric motor of a hoisting plant. The device according to the invention comprises at least one first rotating member moved by the motor of the hoisting plant. The device also comprises a second rotating member connected to the first member through first transmission means. At least one third rotating member is connected to the second rotating member through second transmission means with flexible elements, which develop a transmission ratio equal to unity. The device further comprises a fourth rotating member operatively connected to the rotor of the electric motor. The fourth rotating member and the third rotating member are connected through third flexible-element-transmission means, which develop a transmission ratio equal to unity. The transmission means of the device according to the present invention are designed to enable rotation of said fourth rotating member in a direction of rotation concordant with that of said first rotating member.

摘要： The invention provides an elevator apparatus comprising a cage 1 disposed inside a path of upward or downward movement vertically movably, a counterweight 2 vertically movable with the upward or downward movement of the cage 1, and a lift drive mechanism for driving the cage 1 upward or downward. The drive mechanism comprises a sheave 42 disposed inside the path, ropes 3 extending along a route around the sheave 42, and a drive device 5 in engagement with the ropes 3. The drive device 5 comprises a belt transmission provided alongside the ropes 3 and revolvingly movable along the rope extension route, a mechanism for pressing a belt surface of the belt transmission into contact with the ropes 3, and a drive motor for driving the belt transmission. The cage can be driven upward or downward without using any traction sheave, while the cage can be reduced in weight.
