ATL single-arm pantograph has a number of advantages over ТЛ-13У1 series pantographs:
- Lightweight;
- Lower reduced weight of moving parts that ensures a better handling of wire drops and therefore a better pantograph/wire contact, minimizes contact strip damages (spalls) and improves current collection.
Pantograph is equipped with wear-free atmosphere-resistant bearings allowing for a reliable and lifetime operation.
All said solutions reduce operating costs, extend pantograph service life and slow the wear of strips and contact wire.
