Characteristics

  • Project: 56 new low-floor trams from Duisburger Verkehrsgesellschaft AG (DVG)
  • Category: Infrastructure
  • Employees: over 800 employees
  • Passengers per year: 48.8 million
  • ASSA ABLOY components: +CLIQ master key system from the IKON brand with over 6,300 locking cylinders to date
  • ASSA ABLOY partner: Eisen Schütz Nachfolger GmbH, Duisburg

The challenge

For over 140 years, Duisburger Verkehrsgesellschaft has stood for reliable local public transport in an important transport hub in Germany. Between the Rhine and the Ruhr, DVG ensures that buses and trains travel safely and efficiently on a network of 541.8 kilometres on a daily basis. Around 48.8 million passengers use the service every year - which corresponds to more than 133,700 people per day. This scale places high demands on the locking technology used. A master key system was therefore sought for the new low-floor trams, which could be used to flexibly assign individual access authorisations for employees and external service providers.

Solution

Based on the individual consultation as well as the intensive cooperation and coordination between the project participants - Duisburger Verkehrsgesellschaft AG (DVG), the vehicle manufacturer and ASSA ABLOY - the decision was made to use the mechatronic locking system +CLIQ from IKON. In combination with the SK6 mechanical master key system, +CLIQ enables modern, flexible management of access authorisations and also offers long-term investment protection. Mechanical and mechatronic components can be combined within a system - for example for particularly sensitive areas or applications with increased flexibility requirements. Locking lever cylinders, half-cylinders as well as double and external cylinders, some of which are specially developed for the railway sector, are used. The robust, durable construction, compact design and high reliability meet the requirements of demanding daily operation.
