Real Case A
We had experience of Russian type Guardrail, there are four lines totally:① two wave guardrail roll forming machine, ② U post roll forming machine,③ connection punching line and ④end wind punching line.
This connection is very poplar in Russia to protect the guardrail and car drivers, it works as a buffer strip when there is a impact. The normal thickness is around 4mm. So we adopt forged iron stands and gearbox driving to make sure this machine can work longly in a stable situation in the following 20 years. The punching speed can up to 70 times/minute.
