product description

1.Our 2 Wave 3 Wave Highway Guardrail Repair Machine straightens deformed W-beam & Thrie-beam guardrails, recycles damaged road safety barriers, high efficiency, stable drive, fully automatic for highway maintenance factories.

2 Wave 3 Wave Highway Guardrail Repair Machine

This 2 Wave 3 Wave Highway Guardrail Repair Machine is a specialized cold forming restoration equipment designed exclusively for repairing bent, twisted, dented waste highway guardrails, compatible with both standard 2-wave W-beam guardrail and 3-wave Thrie-beam guardrail widely used on national highways, expressways and provincial roads.

Instead of scrapping deformed guardrails after traffic collisions, this guardrail repair machine reshapes broken guardrail plates back to original standard profiles, drastically cutting raw steel procurement costs for road maintenance contractors, guardrail manufacturing plants and recycling yards.

Core Working Principle

Damaged waste guardrails are fed into the multi-group precision forming roller sets of the 2 Wave 3 Wave Highway Guardrail Repair Machine. Heavy-duty gear reducer and synchronous transmission system deliver constant rolling pressure to gradually straighten torsion, bending and surface indentation. After multi-pass calibration, the restored guardrail reaches factory standard flatness and wave size, reusable for road safety installation.

Key Product Advantages

1. Dual Profile Compatibility One single 2 Wave 3 Wave Highway Guardrail Repair Machine supports both 2-wave W-beam and 3-wave Thrie-beam guardrail restoration, no need to replace main machine frames, only simple roller adjustment to switch production modes, saving workshop space and equipment investment.
2. Heavy-Duty Stable Transmission Equipped with large-size cast iron gear reducer, solid transmission shaft and thickened alloy forming rollers. The whole frame adopts thick steel plate welded structure, anti-vibration, long service life under 24-hour continuous heavy load operation.
3. Automatic PLC Control System Independent electrical control cabinet with start/stop, emergency stop buttons, adjustable feeding speed. Operators only need to place waste guardrails on the feeding rack, the machine completes straightening and shaping automatically, greatly lowering labor intensity.
4. High Restoration Efficiency Processing speed up to 8–12 meters per minute, can handle hundreds of pieces of waste guardrails daily, perfectly matching mass guardrail recycling and repair production lines.
5. Low Operating Cost All forming rollers adopt wear-resistant alloy steel heat treatment, wear resistance and long service cycle; low power consumption, no secondary cutting or polishing required after repair, finished guardrails meet national highway safety component standards.
