Abstract

A braking appliance (1) positioned on the load-suspension device (24) holds the load-suspension device fast by means of frictional engagement on its guide rails (2) while the load suspension device is at a standstill; and overrides the frictional engagement by means of a corresponding command. The load-suspension device is raised by elastic supports (27). The braking appliance contains sensors (8) for detecting the vertically directed brake holding loads.

Description

technical field

[0001] The present invention relates to a device and method for preventing vertical deflection and vertical vibration of the load carrier of a vertical conveyor when it is stopped, by means of frictional engagement to fasten the load carrier to its guide rails at the stop so as to obtain the The desired effect is that this frictional engagement is released when a corresponding control command is present. Background technique

[0002] The following description refers to passenger or freight elevators representing a particular type of vertical conveyor. Accordingly, the elements are denoted by corresponding technical terms related to the field of elevators. For example, a load carrier is represented as an elevator car or car.

[0003] EP0346195 discloses an electromagnetically actuated caliper brake specially designed to restrain the car or counterweight of an elevator to its guide rails by means of frictional engagement. The brake has two double-armed lever...
