Heavy Duty Double Head Hydraulic Decoiler for High-Speed Roll Forming

The double head hydraulic decoiler manufactured by Hebei Xinnuo provides an industrial-grade uncoiling solution engineered for continuous, high-speed metal roll forming operations. Featuring an innovative dual-station rotary structure, this heavy-duty uncoiler allows operators to safely load and prepare a secondary steel coil on the idle mandrel while the primary mandrel feeds material smoothly into the production line. This synchronized workflow effectively eliminates coil changeover downtime and maximizes overall production output.

Equipped with high-precision hydraulic expansion mandrels, our double head hydraulic decoiler automatically expands to clamp raw coils firmly from the inside diameter, preventing slippage and lateral deviation during high-speed unwinding. It handles various materials including galvanized steel (GI), pre-painted galvanized steel (PPGI), cold-rolled carbon steel, and aluminum coils. Built with a rigid welded chassis, it ensures vibration-free continuous operation even under demanding factory workloads.

This automated uncoiling system is engineered to integrate seamlessly into complete roll forming lines, serving as the primary feeding unit for advanced CZ purlin roll forming machines and high-capacity double layer roll forming machines. Backed by over 30 years of manufacturing excellence in Hebei Xinnuo's 100,000 m² production base, each machine delivers long-term durability, precise strip guidance, and reliable automated performance for global steel building manufacturers.

Key Features & Advantages

• Rotary double station design, non-stop coil change: One coil feeding in production while another coil is pre-loaded on the second mandrel. Swapping coils requires zero full line shutdown, greatly boosting overall line efficiency.
• Hydraulic expanding mandrel: Automatically clamps steel coils securely to prevent slipping and sheet deviation. An optional tension brake maintains uniform strip feeding for superior purlin profile accuracy.
• Heavy-duty frame with multiple tonnage options 3T/5T/8T/10T: Rigid welded steel chassis provides dependable stability for heavy coil loading and 24/7 continuous operation.
• Perfect match with C/Z purlin roll forming machine: Works smoothly with GI, PPGI, carbon steel, and aluminum coils, pairing perfectly with levelers in automated roll forming lines.
• Easy operation & labor saving: Single-operator hydraulic control for mandrel expansion and rotation, fully interlocked with the main line PLC for synchronized processing.
• Safety protection & export standard: Built with mechanical and electrical limit protections, an IP54 electrical cabinet, anti-corrosion painting, and robust components for overseas environments.
