Lift Report

The share of elevators requiring modernization and rehabilitation is rising steadily. One of the most important challenges associated with rehabilitation is retroactive attachment of new (or preexisting) guide rails to masonry hoistway walls. The present article is intended to provide a survey of the theoretical fundamentals that have to be observed here. It also presents one solution that the VdTÜV (association of technical inspection services) has worked out in cooperation with representatives of the elevator and screw anchors industries.

The EN 81-28 standard brought about the introduction of the telephone line to the control room as this standard requires new passenger lifts to be equipped with an emergency call system which has a voice connection to a constantly occupied location. It is only natural that modern lift manufacturers want to utilise this telephone connection for remote monitoring and remote parameter setting, so consequently, each manufacturer now offers a monitoring system designed for his own equipment.

Unabated economic expansion is creating a huge market for the elevator industry in China and at the same time offers development opportunities never seen before.

Economic policies characterized by reform and opening trade with the outside world have impacted the elevator industry. The injection of foreign investment funds and the adoption of advanced technologies and modern management techniques have brought about technical progress throughout the industry. As a consequence, the technical standards and quality of Chinese elevator products have joined the ranks of the world’s industry leaders. Above all, incorporating international technical standards and safety regulations has not only lowered the technical barriers to international markets; it has also increased system operating dependability. All this has made a contribution to the safety standard’s rising significantly – parallel to rapid growth in the number of installed systems.
