"Long travel" typically refers to the long distance a bridge crane travels along the length of the workshop (i.e., the direction of the trolley's movement). This places higher demands on the trolley's traveling mechanism, power supply system (such as the conductor rail), and overall stability.
Weihua Long Travel Overhead Bridge Crane Design and Configuration
To achieve stable operation over long distances, Weihua cranes typically employ the following designs and configurations:
1. Double-beam structure as the primary feature: Long travel are often accompanied by large spans or heavy loads. A double-beam box-girder structure provides higher rigidity and load-bearing capacity, ensuring smooth operation.
2. Flexible power supply solutions: Long-distance movement requires a reliable power supply, often achieved through safety conductor rails or cable reels.
3. Precise control and positioning: To ensure positioning accuracy over long distances, variable frequency speed control and micro-speed/inching functions are commonly used; high-end equipment also features automatic positioning systems and anti-sway functions.
4. Automation and Intelligence: In scenarios such as scrap yards and stockpiles, long travel
overhead cranes can be configured with a fully automated unmanned operating system, integrating 3D warehouse scanning and 5G transmission for remote scheduling.
Long travel overhead cranes primarily serve the needs of covering large work areas:
Steel and Metallurgy: Spans up to 28.5 meters, enabling fully automated grabbing, dumping, and transfer in harsh environments with high temperature, high humidity, and high dust.
Warehousing and Logistics: Highly efficient for transporting heavy raw materials or finished products on tracks up to 180 meters long.
Power Generation and Manufacturing: Used in turbine plants or heavy assembly workshops for the safe transport of precision heavy equipment over ultra-long distances.
