Guardrail machine
The XINNUO XN-W4.0 is an industrial-strength roll forming system engineered for the production of standard W-beam highway guardrails from heavy-gauge material. Designed to handle steel thicknesses up to 4.0mm (235MPa yield strength), this line features a reinforced 450H frame and an massive 115mm solid shaft system. Driven by high-torque dual 15kW motors and equipped with a 2-set precision punching unit, the XN-W4.0 ensures maximum structural stability and consistent profile geometry for long-distance highway safety projects where superior impact resistance is required.
Product Overview
This XINNUO XN-W4.0 production line is a dedicated solution for manufacturers supplying high-specification road safety barriers. By utilizing a 115mm solid shaft architecture and a dual-motor configuration, the machine eliminates the risk of profile deviation when processing 4.0mm thick coils. The integrated hydraulic pre-cutting and 2-station punching systems allow for the high-precision creation of bolt holes, ensuring every finished W-beam panel meets strict international transport infrastructure standards.
Main Features
- Dual 15kW High-Torque Drive: Utilizes two 15kW main motors (30kW total) to provide the immense force required for uniform forming of 4.0mm high-strength steel.
- 115mm Reinforced Solid Shafts: Oversized 40Cr solid shafts with a 115mm diameter provide unmatched rigidity, preventing any "spring-back" or bending under heavy loads.
- Extra-Stable 450H Frame: Built on a heavy-duty 450H steel chassis with a 30mm medium plate structure, designed to absorb vibration during high-thickness forming.
- 2-Set Precision Punching: Includes two dedicated hydraulic punching stations for accurate bolt hole and connection slot placement, fully adjustable via PLC.
- Premium GCr15 Rollers: Rollers are manufactured from GCr15 bearing steel, precision-machined and vacuum heat-treated to HRC 58-62 for long-term wear resistance.
- 2.5-Inch Industrial Chain: Features a heavy-duty 2.5-inch chain transmission for efficient power delivery across all 18 forming rows.
