Hand-Held Clinch Unit ULG SN4

Hand-Held Clinch Unit ULG SN4

The pneumo-hydraulic BTM clinch and pierce unit ULG SN4 combines high joining force with rapid cycle time.

The integrated air-oil-booster runs silently and completely vibration-free. 6 bar air supply activates the drive system. The joining stroke can be released by a hand lever. Also a foot pedal release is available. BTM ULG clinch units offer an high level of integrity in use. The well-balanced, light-weight and ergonomical construction of this unit minimizes the stress on the user.

The modular design of the mobile clinching units ULG-SN4 allows the use of a wide range of tool holders, such as C-frame, scissor heads and various special holders. These can be changed in just a few steps while the drive unit remains the same.
