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.

Full-colour touchscreen control

The ST 4175 and ST 4250 incorporates Stertil Koni's revolutionary ebright Smart Control System. This is a 7" fullcolour touchscreen with owner/user-configurable options. ebright allows two 4-Post lifts in tandem configuration to be operated at the same time. Presenting all relevant information at a glance. 

Four Post Tandem Ramp

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 active throughout the lifting process. The specially integrated pressure-relief valve prevents overloading on each lifting unit.
