Automatic Line for 2 and 3 Bumps Crash Barriers Production

Line able to produce crash barrier 2 and 3 bumps production with the same machine.


OMM provide wide and flexible solutions by its latest automatic line for 2 and 3 bumps crash barriers production with cutting and punching on fly high accuracy making suitable this machine for barriers production plant.

OMM’s automatic line for 2 and 3 bumps crash barriers can easily be operated and carried thanks to its user-friendly interface.

The process starts from coils properly cut to the correct width for 2 and 3 bumps that are loaded on the decoiler drum. The ribbon goes ahead in order to meet the shearing machine where is cut the initial part and the final part of the coil because the end of the coil will be welded at the same time with the initial part of the new coil in feeding, that means saving time. Then there is a movable profiling machine that translates rails based on the production done because the same profiling machine is able to realize barrier with 2 bumps or barrier with 3 bumps that means to have only one line and produce the complete production range and save money.

The machine has been designed to accept the flattened sheet and to cold forming giving a profile conform the ASHTOO – RAL A – RAL B and SINA norms.

Tecnichal and main features

After the forming machine follows a truck motorization group for punching side slots, central slots and the barrier cutting. During the blank sliding, in flight, at the same time in only one descent stroke are made the side slots, the central slots and the barrier cutting through hydraulic cylinders. After this station the barrier is ready to go on the unloading station for the following stacking and unloading. The barriers packs are ready to be galvanized.
