Double-girder bridge crane for the paper industry – Intelligent lifting of heavy-duty paper rolls, efficiently empowering the entire papermaking process.
Heavy-duty load capacity, adaptable to all paper roll sizes. Utilizing a heavy-duty double-girder bridge structure, the rated lifting capacity covers 10t~100t+, enabling precise lifting of extra-large diameter heavy paper rolls (covering all types of paper rolls, including cultural paper, packaging paper, and specialty paper). A single unit can meet the heavy-duty lifting needs of paper rolls throughout the entire process from the production line and rewinding section to the finished product warehouse. The structural strength has been verified under heavy-duty conditions, exhibiting resistance to deformation and wear, making it suitable for high-frequency operation scenarios in paper mills.
Technical Parameters:
| Rated Lifting Capacity | 10t~100t / Single Unit | Customizable 120t | Ultra-heavyweight paper roll lifting | Covers Φ1.5m~Φ5m ultra-large diameter heavy-duty paper rolls |
| Span | 10.5m~35m | Suitable for large-span production workshops in paper mills | Matches production line - rewinding area - finished product warehouse cross-area layout |
| Lifting Height | 8m~25m | Customizable according to finished product warehouse stacking height | Meets the needs of multi-layer heavy-duty paper roll high-level stacking |
| Working Level | M5~M7 | Optional for heavy-duty high-frequency scenarios | M8 | Suitable for continuous high-intensity operations in paper mills |
| Positioning Accuracy | ±5mm | Frequency conversion + electronic control calibration optimization | Precise paper roll placement, avoiding collision damage |
| Lifting Equipment | Dedicated paper roll lifting equipment (hydraulic brake/adaptive type). Adaptable to the curved surface of paper rolls, anti-slip and anti-detachment, does not damage the edges of the paper rolls. |
Wireless Remote Control: Intelligent, Precise, and Unrestricted Control
Standard configuration includes a 50-100 meter wireless remote control system, allowing a single person to remotely control the start, stop, speed adjustment, steering, and precise placement of paper rolls, freeing them from cable constraints. The remote control panel integrates a heavy-load status display, monitoring paper roll weight, operating speed, and equipment status in real time, with control precision reaching ±5mm. This prevents bumps and wear during paper roll handling, ensuring paper quality.
Smooth Operation, Protecting Paper Roll Quality
Double beams with a variable frequency speed control system ensure smooth, shock-free starting and braking, and prevent paper roll swaying or displacement during operation. High-precision machined tracks, combined with a double-beam synchronous drive design, are suitable for long-distance, large-span workshop layouts in paper mills, enabling efficient flow of paper rolls from the production line to the storage area and significantly reducing manual handling losses.
Comprehensive Safety, Adaptable to Paper Mill Conditions
Equipped with multiple safety protection systems to address the unique environment of paper mills, characterized by humidity, dust, and heavy loads: overload limiter, upper and lower limit protection, anti-collision device, emergency stop button (remote control + vehicle-mounted dual configuration), and electrical leakage protection; the main beam and electrical system feature corrosion-resistant and moisture-proof designs, adapting to the high-humidity environment of paper mills and eliminating hoisting safety accidents.
High Efficiency and Durability, Cost Reduction and Efficiency Improvement
The double-beam structure design enhances the equipment's operational stability and service life; core components are made of wear-resistant alloy steel, resulting in long maintenance cycles; electric drive with zero emissions and low noise meets the green production requirements of paper mills; strong continuous operation capability matches the 24-hour operation rhythm of paper production lines, reducing downtime and lowering labor and equipment maintenance costs.
Applicable Scenarios
Widely used in various paper mill production lines for paper roll hoisting, rewinding section transfer, heavy paper roll stacking in finished product warehouses, and paper roll inter-workshop transfer, making it a core piece of equipment for heavy-duty paper roll hoisting in the paper industry.
