Mitsubishi PLC Control Tunnel Plate Roll Forming Machine Thickness 2-6mm

Tunnel Liner Plate is one of the most versatile segmental corrugated steel plate systems on the market today. Designed specifically for lining soft ground tunnels and relining existing conduits under highways and railroads, its applications extend to caissons, vertical shafts, mine entries and much more. Since complex tunnel lining equipment is not required, installation is quick and easy with minimal disruption to road users and the surrounding environment. A variety of material options and coatings are available to optimize service life requirements.

Feeding & leveling

The leveling roller's mechanical property such as rigidity and roughness concentration of the surface are rising very much after hardening and tempering. It includes pinch roll and leveling roll. The pinch roll can adjust along. The leveling roll uses the whole structure. There are two adjusting point at the front and the end. It can form a certain banked angle to improve the leveling quality. The feeding port of the leveling machine has a pair of guide plain-barrelled roll and two pairs of guide vertical roll. The guide vertical roll can moves centered or moves at the same time. It is adjusted by hand wheel, so it is convenient to centered
