Wedge Type Hydraulic Decoiler with Trolley

**Applications and Features**
The Wedge-Type Hydraulic Decoiler with Trolley integrates a wedge-type mandrel structure-characterized by high expansion force-with a hydraulic loading trolley, making it the flagship model for high-end production lines. This wedge-type hydraulic decoiler with trolley is capable of handling heavy steel coils weighing over 12 tons while simultaneously enabling rapid coil changeovers of varying specifications via the trolley; it is particularly well-suited for mixed-line production environments involving multiple product varieties and small batch sizes. The equipment comes standard with a PLC-controlled closed-loop tension system, automatic centering, and a remote monitoring interface. Choose the Wedge-Type Hydraulic Decoiler with Trolley to achieve automated and flexible heavy-duty decoiling operations.

**Structure and Operation**
The main unit features a wedge-type expansion mandrel (comprising inclined dovetail slots, wedge blocks, and a large-diameter hydraulic cylinder), offering an expansion stroke that is 40% greater than that of standard models, thereby providing exceptional adaptability to variations in steel coil inner diameters. The loading trolley of the Wedge-Type Hydraulic Decoiler with Trolley operates on an independent hydraulic system, allowing for stepless speed control during both lifting and lateral travel; the trolley cradle is equipped with lateral guide wheels to prevent the coil from rolling off. The operational sequence is as follows: Trolley retrieves coil → Lifts to center height → Moves forward to insert coil onto mandrel → Mandrel expands to secure coil → Trolley retracts. Additionally, the frame of the wedge-type hydraulic decoiler with trolley features hydraulic lateral shifting capabilities, and a heavy-duty support arm is positioned at the front of the decoiling drum. The gearbox utilizes a forced lubrication and water-cooling system, while the variable-frequency drive enables a maximum decoiling speed of 20 m/min, effectively meeting the requirements for low-speed, high-tension processing of thick-gauge plates.

**Customization and Service**
Mandrel dimensions and trolley parameters can be customized to accommodate specific requirements regarding maximum coil weight, width, and inner diameter range. The Wedge-Type Hydraulic Decoiler with Trolley is available for order starting from a single unit, with customizable color options. Payment terms are 30% upfront deposit and 70% balance payment; trade terms include EXW, FOB, and DDP. The equipment comes with a one-year warranty and undergoes comprehensive machine-wide joint commissioning prior to shipment; we offer on-site installation services or video-guided installation support, and third-party inspections are welcome. Large components are shipped as bare cargo, while smaller parts are packed in wooden crates. Choose the Wedge-Type Hydraulic Decoiler with Trolley to experience a comprehensive, one-stop solution for heavy-duty decoiling.
