Extended Tandem Configurations

For long vehicles the Stertil-Koni 4 Post lift can be extended in tandem configuration, ideal for articulated buses and other long vehicles up to 11.5 metres.

The design of the Stertil-Koni 4 Post lift means that  jacking beams can also be mounted to the lift allowing for more space on the workshop floor for example with wheel changes.

Extended Tandem Configurations

Safety: Independent Locking System

Mechanical Locking: the highly safe Stertil-Kon patented gravity mechanical locking system works entirely independently of the lifting system
and is permanently enabled. 

Hydraulic: each lifting cylinder is fitted with an oil flow control valve that is enabled throughout the lifting process. The specially integrated overpressure valve prevents overloading on each lifting unit.
