Abstract:
A testing device includes a receiving unit for electromagnetic signals arranged on a carrier element to be tested to generate test data from received electromagnetic radiation. The test data are evaluated in a processing system to determine a deviation of the test data from a nominal state of the carrier element. The testing device is used to test a carrier element of an elevator installation on which the elevator car is suspended.

Abstract:
With this set or reference value transmitter which is controlled by a set or reference value clock pulse generator or transmitter regulation of the running-up or acceleration of electric motors, such as asynchronous motors, can be kept under control also in the upper rotational speed ranges of the motor by adapting the displacement path-reference value characteristic curve to the displacement path-actual value characteristic curve. For this purpose the reference value transmitter comprises a correction member, by means of which the displacement path-regulation deviation is supervised in such a way that if the greatest displacement path-regulation deviation associated with the maximum power of the adjusting or positioning members is exceeded, the clock pulse frequency of the reference value clock pulse transmitter is reduced proportionally to the excess. The displacement path-reference values are supplied to the displacement path regulation circuit in correspondingly larger time intervals until the greatest displacement path-regulation deviation is fallen short of, whereupon the reference value transmitter continues to operate with the original clock pulse frequency.

Abstract:
A method, a system and a computer program product for computer-assisted furnishing of materials in elevator construction, wherein materials are provided with a readable or writable data transmitter, these materials are furnished, data of the data transmitter are written or read with computer assistance and these data are checked with computer assistance.
Abstract:
An elevator system with a car or platform to transport passengers and/or goods as well as with a counterweight, which are arranged as traversable or movable along a travel path, and which are coupled and/or with a drive by a suspension element interrelating their motion. The suspension element is guided and/or driven by a traction sheave and/or a drive shaft and/or a deflecting pulley. The suspension element is sheathed and/or belt-type, with a first layer made of a first plasticizable and/or elastomeric material, containing a first exterior surface, and with at least one tension member—rope-type, tissue-type, or comprising a multitude of partial elements—that is embedded in the first layer of the suspension element. A manufacturing procedure for one of the suspension elements is provided.
Abstract:
An elevator the drive unit is arranged laterally in a top section of an elevator shaft and, as seen from a shaft door opening, at a side wall of the elevator shaft. At least one cable is guided over deflecting rollers of a support frame of the elevator car and over deflecting rollers of the counterweight and serves as a support and drive cable for the elevator car or the counterweight. The cable is guided over a drive pulley of the drive unit and is arranged transversely to the side wall. The support frame is constructed as a rucksack frame with an upright frame guided by guide rails and a horizontal base frame on which the elevator car is arranged. On travel to the uppermost stopping point, the upper part of the elevator car travels past the drive unit.
Abstract:
In this wireless remote control system, control signals and reporting-back signals are bidirectionally transmited between at least one portable transmitter-receiver unit, a stationary transmitter-receiver unit and a control. The portable transmitter-receiver unit contains a microprocessor and is carried, for example, by hand or in a clothing pocket. Control commands are input, depending upon their frequency of occurrence, by way of a ten-key keyboard, fixed keys or stored in a storage and transmitted as control signals via an operating mode selector switch selectively in either one of the operating modes "manually by push-button" or "automatically, permanently". The signalling is non-public and on an indicator. The stationary transmitter-receiver unit with microprocessor is mounted stationarily in the transmission range of the associated portable transmitter-receiver unit and communicates the received control commands to the control. This remote control permits location-independent input of public and non-public operating requests into elevator installations and thereby a conveniently and secure call issue to protected storys. The method and the equipment can likewise be used for operating doors, escalators, turnstile and so forth and thus are generally suitable for controlling access and facilitating personnel traffic in buildings.
