procedures for the examination of the treibfähigkeit a driving sheave

摘要

In order to provide a method for testing the drive capability of a drive pulley (1) of an elevator installation (10), wherein the elevator installation (10) of the further at least one over the drive pulley (1) is guided within the supporting cable (2), one at one end of the supporting cable (2) suspended first elevator body. (3) and a on the other end of the supporting cable (2) suspended second elevator body. (4) and said two elevator body. (3, 4) as a function of an angle of the drive pulley (1) are movable in opposite directions to one another, comprising: a) moving the first elevator body. (3) according to the top, b) brakes of the drive pulley (1),c) measuring a brake acceleration of the first elevator body. (3), which provides an improved is not at all, it is proposed that an acceleration of at least as a function of the measured brake acceleration, a mass of the first elevator body. (3), a proof mass (9), a safety factor being taken into account and the gravitational acceleration is calculated in such a way that the calculated acceleration in the case of hypothetical carrying out the steps aa) moving the first elevator body. (3) with the proof mass (9) according to the bottom, bb) brakes of the drive pulley (1), a hypothetical brake acceleration of the first elevator body. (3) in step bb), and the driving ability is judged to be adequate when the calculated acceleration of a hypothetical delay of the first elevator body. (3) in step bb) corresponds to.n="17"
