The special gun of the TAURUS 2 Axial eco can be integrated in assembly benches, installations or partially automated workstations and facilitates flexible and ergonomically efficient manual working procedures in applications with restricted access that therefore require riveting from above. In order to make sure that the parts to be riveted make contact without any gaps and that the setting head is in contact with the material, the TAURUS 2 Axial eco can also be supplied with a spring-loaded trigger system. A compressed air supply is additionally required for reliable mandrel evacuation. Depending on the application, this is preferably achieved via the balancer with valve or the time delay valve. The TAURUS 1–4 Axial eco series is an inexpensive entry-level model for special applications.
