MTC just finished the assembling of a hgihway guardrail roll former. This highway guardrail roll former manufactures both W beam and 3 Wave guard rails without replacing different rolling tools and cutting dies.

Firstly, this roll forming machine has been known as the name w beam and 3 wave interchangeable highway guardrail roll forming machine. There are w beam or 2 wave highway guardrail roll forming machine and 3 wave highway guardrail roll forming machine in the markets. However, people prefer an interchangeable equipment that can produce both 2 wave and 3 wave guard rails because it could save more money and working areas.

Actually, it won’t take too much time switching between the production of 2 wave and 3 wave guardrails. “It’s esay to switch or make change between W beam and 3 wave or Thrie Beam. The last few roll forming stations of the equipment will be adjusted or diseffective, and also the cutting dies shall be changed for producing different guard rails (w beam or 3 wave).”

This highway guardrail roll former makes guard rails out of 1.8-3.5mm thick Galvanized steel strips with 480mm and 750mm widths adjustable. The punching tool stays at the feeding of the crash barrier roll forming machine with different punching holes compositions available. The equipment is running under the control of PLC system, which consists of HMI, Inverter and two Encoders. (More on product page INTERCHANGEABLE W & THRIE BEAM GUARDRAIL ROLL FORMING MACHINE )

Main components of this Highway Guardrail Roll Former, Guardrail Roll Forming Machine:

• Manual decoiler
• Feeding unit
• Hydraulic cutting tool
• Roll forming unit
• Transmission unit
• Cutting unit
• Hydraulic unit
• Control system
• Run-out tables

This machine has the same design as a 3 wave highway guardrail roll forming machine, like the roll forming stands structure, main components, transmission system and control system and so on.

To be specific, the roll forming stands structure is separate type, and transmission is gear-boxes and universal joint shafts. However, the different part is rolling tools. The rolling tools for the interchangeable equipment is compatible for both 2 wave and 3 wave forming rollers.
