Constantia Teich - Longer service life
With a vehicle fleet of nearly 100 electric forklift trucks and more than 100 traction batteries, it is always worth taking the time to look at ways to lengthen battery service life. At Constantia Teich GmbH, the solution is battery chargers from the Fronius "Selectiva" range with Active Inverter Technology.
Constantia Teich GmbH is one of the specialists for packaging material. The company, with headquarters at Weinburg in Austria, 60 km west of Vienna, is part of Constantia Flexibles, a world leading supplier of flexible packaging materials.
The manufacturing processes vary hugely and are carried out on different machines that need to be linked in the production flow. This role is fulfilled by a fleet of forklift trucks consisting of about 95 electric forklifts.
It was primarily the short service life - a mere three to four years - of what are expensive batteries that led to a move at Constantia Teich GmbH to look more seriously at the question of "batteries and charging technology". In the past, the company simply took the word of the forklift truck manufacturers and followed their suggestions in terms of chargers. For the most part, they proposed and supplied 50 Hz transformer technology.
Investigations demonstrated that service life was significantly impaired by the battery heating up during the charging process.
The main aspects that won Constantia Teich over were the compact, space-saving design of the Fronius devices and easy programming of the ideal charging characteristics on the integrated display. "With heavy-duty everyday use, the batteries now achieve a service life of six to seven years and significantly more with light use. This is what really counts for us", added Franz Schmied.
