Double-girder BRidge Crane for Heavy Industrial Workshops
Double-girder bridge cranes for heavy industrial workshops are core equipment suitable for large-tonnage, large-span, high-frequency and heavy-load scenarios. Composed of a double-girder bridge frame, a trolley hoisting mechanism, and a carriage running mechanism, it covers the entire workshop area through three-dimensional movement (longitudinal for the carriage, horizontal for the trolley, and vertical for the hook), and is naturally suited to the heavy industry's "heavy lifting and wide span" needs.
Technical Parameters:
| Lifting Capacity | 5~550 tons (including main and auxiliary hooks, such as 80/20 tons) |
| Span | 10.5~31.5 m |
| Lifting Height | 6~30 meters (customizable up to 50 meters) |
| Work Duty | A5 (medium load) ~ A7 (extremely heavy load) |
| Lifting Speed | 0.5~10m/min (variable frequency, dual-speed mode) |
Precisely adapted for heavy industry scenarios
Metallurgical workshops: Lifting ladles (200-300 tons) and steel coils (50-100 tons). High-temperature-resistant coating (600°C resistant) and forced cooling ensure motor operation in high-temperature environments ≤70°C.
Power industry: Lifting generator set stators (80 tons) and transformers. Micro-motion accuracy of 0.1m/min and millimeter-level docking base.
Heavy machinery: Handling machine tool beds (90 tons) and pressure vessels. Positioning accuracy of ±5mm ensures machining and assembly precision.
Port terminals: Loading and unloading heavy containers (50-100 tons) and ship sections (500 tons). Double-beam torsional resistance ensures hoisting levelness ≤0.5°.
