As a complementary equipment, a 3 wave highway guardrail roll forming machine has been designed for the manufacturing of 3 waves or thrie beams guard rails for highway or expressway construction.
There are always two types of road beams or crash barriers placed on the two sides of highway, or expressway: Two wave guard rails or W-shaped beams, and Three wave or thrie beam crash barriers. Most of the guard rails are 2 wave or w shaped beams (More about w beam or 2 wave highway guardrail roll forming machine) but in some occasions, 3 wave or thrie-beam crash barriers are necessary to installed on the highway or expressway (the most common applications for 3 wave or thrie-beam guardrails are bridges on highways , or exit and entrance of tunnels on highways).
Brief introduction of 3 wave highway guardrail roll forming machine:
This 3 wave or thrie beam crash barrier roll forming machine is a cost-effective and heavy duty production line. It produces 3 wave guard rails fully automatically and continuously out of galvanized steel (sometimes cold rolled steel) of 2-3.5mm thickness in the same way as a 2 wave or w beam highway guardrail roll forming machine does, from material feeding all the way until running out from the main machine.
Not like a 2 wave or w beam highway guardrail roll forming machine We offer only gear-box and universal-joint shafts transmission system, and separate forming stands structure for a 3 wave or thrie beam crash barrier roll forming machine. (There is interchangeable highway guardrail roll forming machine for the production of both w beam and thrie beam.)
Main components for a thrie beam or 3 wave crash barrier roll forming machine are listed as a 10 Ton hydraulic decoiler with coil car, a feeding guide, a leveler, a hydraulic punching tool, a roll forming part, a hydraulic cutting tool, a transmission system, a PLC control cabinet, a hydraulic oil pump and runout tables.
