Abstract

Die Erfindung betrifft eine geführte Hebeeinrichtung mit einer Bühne, einem Korb oder einer Kabine,
- mit mindestens einer Führungsschiene (42), an welcher die Bühne, der Korb oder die Kabine verfahrbar geführt ist,
- mit einer Fangvorrichtung, die direkt oder indirekt an der Bühne, dem Korb oder der Kabine befestigt ist und eine Anlagefläche (45) für eine in Bewegungsrichtung verlaufende Bremsschiene oder für die Führungsschiene (42) aufweist,
- sowie mit einer Auslöseeinrichtung (14, 15, 16, 17, 18) für die Fangvorrichtung, welche bei einer vorgegebenen unzulässigen Beschleunigung der Bühne, des Korbs oder der Kabine derart mit der Fangvorrichtung zusammenwirkt, dass die Anlagefläche (45) in reib- bzw. kraftschlüssigen Kontakt mit der Bremsschiene oder der Führungsschiene (42) tritt, um die Bühne, den Korb oder die Kabine abzufangen,
- wobei die Fangvorrichtung so ausgelegt ist, dass die durch den reib- bzw. kraftschlüssigen Kontakt zwischen der Anlagefläche (45) und der Bremsschiene oder Führungsschiene (42) maximal erzeugbare Bremskraft die Gewichtskraft der Bühne, des Korbs oder der Kabine unter Volllast überkompensiert. Außerdem ist ein mit der Fangvorrichtung zusammenwirkendes Dämpfungsglied (52, 53, 55, 60) für ein rampenartiges Ansteigen der Bremskraft vorgesehen, wobei das rampenartige Ansteigen der Bremskraft so gewählt ist, dass eine nicht voll beladene Bühne, ein solcher Korb oder eine solche Kabine zum Stillstand kommt, bevor die maximale Bremskraft wirkt.

The invention relates to a guided lifting device with a stage, a basket or a cabin,
- With at least one guide rail (42) on which the stage, the basket or the cabin is movably guided,
- having a safety device directly or indirectly fixed to the platform, the basket or the car and having a bearing surface (45) for a direction of movement of the brake track or the guide rail (42),
- And with a triggering device (14, 15, 16, 17, 18) for the safety gear, which cooperates with the safety device for a given impermissible acceleration of the stage, the basket or the car in such a way that the contact surface (45) in rubbing or force-locking contact with the brake track or guide rail (42) to intercept the platform, basket or cab;
- Wherein the safety gear is designed so that by the frictional or non-positive contact between the contact surface (45) and the brake rail or guide rail (42) maximum producible braking force overcompensates the weight of the stage, the basket or the cabin under full load. In addition, a cooperating with the safety device attenuator (52, 53, 55, 60) is provided for a ramp-like increase in braking force, wherein the ramp-like increase in braking force is selected so that a not fully loaded stage, such a basket or such a cabin for Standstill comes before the maximum braking force acts.
