Outdoor Heavy Lifting: Stable, Accurate, and Powerful – Double-Girder, Double-Hook Gantry Crane
No More Worries About Large-Tonnage Operations. Are containers in open yards being lifted crookedly? Is lifting heavy steel billets taking half a day with frequent power outages? Is operating from the operator's cab at height always a safety concern? This industrial rail-mounted double-girder gantry crane (double hooks + cable reel + wireless remote control) completely eliminates all the headaches associated with outdoor heavy-tonnage lifting.
Technical Parameters:
| Load Capacity | Rated Load Range | Dual Hook Configuration (Main/Auxiliary Hook) | Working Class (GB/T 3811) |
| Medium | 50~100 tons | Main hook: Rated load; Auxiliary hook: 20~40 tons (independent lifting) | A6 (Medium-frequent heavy-duty operations) |
| Heavy | 100~200 tons | Main hook: Rated load; Auxiliary hook: 30~60 tons (independent lifting) | A7 (Frequent heavy-duty operations) |
| Extra-heavy | 200~300 tons (expandable) | Main hook: Rated load; Auxiliary hook: 50~80 tons (independent lifting) | A8 (Extra-heavy continuous operations) |
Why is it a leading player in outdoor lifting?
1. Double Girder, Double Hook: Stable and Level Lifting Even for Large Tonnages
Rated load capacity covers 50~300 tons (ultra-heavy-duty can be customized). The double hooks support synchronous/independent lifting: They can balance the load on long wind turbine towers and irregular steel components, preventing tilting and collisions; a single hook can also lift small-tonnage goods independently, making it a versatile machine.
1. **Double-beam structure for high rigidity:** Deflection during hoisting is less than 1/1000 of the span, ensuring stable suspension of heavy loads and allowing for seamless alignment with trucks/racks.
2. **Cable reel power supply:** Uninterrupted outdoor operation. No need for temporary cable runs or frequent battery changes—the cable reel automatically winds up and unwinds cables, suitable for long-distance rail-mounted operation in open areas. It can operate continuously for over 8 hours without interruption, perfectly meeting the continuous operation needs of freight yards and construction sites.
3. **Remote control + ladder:** Maximum safety and efficiency. Wireless remote control operation within 100 meters eliminates the need to climb into the cab or stand next to heavy loads, avoiding the risks of falls and load swaying. Equipped with dual emergency stop buttons (remote control + machine body) for one-button stop in case of emergency.
The built-in ladder and top guardrail eliminate the need for scaffolding for equipment maintenance, making high-altitude maintenance easier and safer.
4. Rail-Mounted Operation: Precision "Down to the Millimeter" The fixed rail route ensures lifting and positioning accuracy of ±5mm, allowing for "one-shot" container docking with trucks, billet loading into furnaces, and component placement, increasing lifting efficiency by 30% compared to ordinary cranes.
These scenarios are where it's most effective:
Open-air freight yards/ports: Loading, unloading, and transshipment of containers and heavy bulk cargo containers;
Heavy manufacturing plants: Cross-regional transport of large-tonnage workpieces such as billets and machine tool beds;
Wind power/infrastructure construction sites: Installation and placement of large components such as towers and precast beams;
Metallurgical/chemical storage areas: Storage and relocation of heavy storage tanks and reactors.
