Straightener Roll Changing Overhead Crane: Automated Roll Handling for Straightening Machines
Straightener Roll Changing Overhead Crane is a specialized crane designed and manufactured for replacing straightening rolls in straightening machines within the metallurgical industry.
In metallurgical production, rolling different profiles requires timely and rapid replacement of the corresponding rolls. By integrating automatic control, precise positioning, anti-sway control, and a dedicated hydraulic clamping system, this crane enables fully automatic lifting, transfer, and replacement of straightening rolls. As a result, it significantly improves roll-changing efficiency and enhances the operational stability of the production line.
Technical Features of Straightener Roll Changing Overhead Crane
Automatic Precision Positioning Control
- Equipped with a PLC intelligent control system, enabling precise positioning of the lifting device in X, Y, and Z directions.
- Hoisting accuracy is maintained within ±1 mm, and travel positioning accuracy within ±3 mm, ensuring precise roll pick-up and placement.
Anti-Sway Control Technology
- The movable pulley system uses a staggered arrangement with multiple wire ropes intertwined, combined with a rope-pull encoder to monitor hoist sway in real time.
- Keeps the lifting device stable during transport, preventing roll swinging and ensuring safety and stability.
Fully Automatic Hydraulic Clamps
- Independently developed fully hydraulic hoisting device with automatic detection capabilities.
- Specialized roll clamps accurately grasp, hold, and release rolls, enabling fully automatic operation.
Multi-Roll Lifting Capability
- Supports simultaneous replacement of multiple roll sets (up to 10 sets), improving roll-changing efficiency.
- Multiple hydraulic clamps lift in synchronization under intelligent control, maintaining stability and levelness.
Precision Sensing and Monitoring
- Automatically monitors key work areas and the entire hoist operation process, issuing alerts when necessary.
- Dynamically detects swing and positioning deviations to ensure operational safety and equipment reliability.
Highly Integrated Intelligent Control
- Combines multi-set synchronized grasping, hydraulic clamps, and intelligent monitoring into a complete automated roll-changing solution.
- Can automatically perform roll-changing tasks based on commands, reducing manual intervention and enabling intelligent operation.
Functions of Straightener Roll Changing Overhead Crane
- Automatic Roll Gripping: The crane automatically identifies and grips the rolls to be replaced using fully automatic hydraulic clamps.
- Automatic Travel to Roll-Changing Position: It moves along a preset path, smoothly transporting the rolls to the roll-changing station of the straightening machine.
- Roll Placement and Replacement: The crane precisely positions and suspends the rolls into the straightening machine, completing the roll-changing operation.
