Product Description
Engineered and built at our specialized metallurgical machinery base in Jingjiang, our Steel Plate Turnover Machine is a heavy-duty mechanical handling unit installed in the finishing lines of medium-and-heavy plate mills to rotate steel plates 180 degrees from one side to the other. Drawing upon 26 years of heavy fabrication experience supplying top-tier steelmakers like Baowu and POSCO, we manufacture each Steel Plate Turnover Machine utilizing a twin-arm crank-and-rocker mechanism powered by an electric motor and heavy-duty gear reducer. By synchronizing the turnover arms with an offset 120-degree crank geometry, this robust Steel Plate Turnover Machine delivers continuous, low-speed, high-torque rotation with minimal dynamic impact, enabling surface inspectors to evaluate both plate faces thoroughly without scratching the product or slowing the finishing pace.
Applications
Medium & Heavy Plate Finishing Lines: Turning heavy plates 180° for two-sided visual and ultrasonic surface inspection.
Plate Grinding & Conditioning Bays: Flipping conditioned plates for deburring, edge milling, and defect grinding.
Shipbuilding & Pressure Vessel Plate Processing: Handling thick structural plates prior to ultrasonic testing and marking.
Clad Steel Plate Lines: Turning composite and clad plates to verify bond integrity and surface finish on both faces.

Customization Capabilities
Adjustable Linkage Geometry: Threaded or modular link rods allow operators to adjust turnover arm strokes, minimizing impact on thin gauges while maintaining torque for thick plates.
Continuous One-Direction Motor Rotation: Mechanical linkages convert unidirectional motor rotation into a complete 180° turn and return stroke, simplifying electrical control logic and reducing motor wear.
Surface-Cushioned Arm Liners: Contact surfaces fitted with replaceable polyurethane, brass, or soft-alloy wear strips to prevent marking of stainless, alloy, or clad plates.
Synchronized Multi-Stand Layouts: Modular mechanical tie-shafts or electronically synchronized multi-stand setups to accommodate extra-long plates without twisting.
Zero MOQ Restriction: Custom-designed for single finishing-line retrofits or complete greenfield processing lines.
Quality Control
Manufacturing Accreditations: ISO 9001:2015, ISO 14001:2015, and ISO 3834-2 welding quality management.
Full Process QR Code Traceability: Every forged crank, turnover arm, main pivot shaft, and bearing housing carries a serialized QR code linked to certified test records.
Weld & Stress Verification: 100% Ultrasonic Testing (UT) and Magnetic Particle Testing (MT) on all structural arm welds; stress relief annealing performed on all heavy weldments.
Shop Load & Kinematic Testing: Complete workshop dry-run and load simulation to verify 120° crank synchronization, arm trajectory, and noise levels.
Heavy Export Packaging: Robust steel transport bases, greased machined journals, moisture barrier wrapping, and timber crate protection for ocean transit.
FAQ
Q: How does the crank-and-rocker mechanism reduce impact when flipping heavy steel plates?
A: The 120° crank offset geometry slows the turnover arm down near the transition dead center. Combined with adjustable connecting rods and variable-frequency motor control, this ensures the plate transfers smoothly from the lifting arm to the receiving arm with minimal shock.
Q: What is the typical manufacturing lead time for a plate turnover unit?
A: Fabrication and shop testing typically take 3 to 4 months from engineering drawing approval to factory dispatch.
Q: What warranty coverage do you provide?
A: We provide an 18-month warranty from site arrival or 12 months from commercial operation (whichever comes first), backed by responsive technical support.
Q: What payment terms and currencies do you support?
A: We operate under EXW and FOB terms. Payments follow our standard schedule: 30% advance deposit, 40% manufacturing milestone payment, and 30% balance prior to export shipment, payable in USD, EUR, or RMB.
