Double Girder Gantry Crane | Main and Auxiliary Double Hooks + Wireless Remote Control, the Ultimate Choice for Outdoor Operations
In open freight yards, busy construction sites, or harbors and docks swept by sea breezes, outdoor operations are always a rigorous test of equipment performance. Our double girder gantry crane, with its efficient configuration of main and auxiliary double hooks and flexible wireless remote control, is specifically designed for complex outdoor working conditions, making heavy-duty loading and unloading easier and safer.
Techanical Parameters:
| Rated Lifting Capacity | Main Hook: 5t~320t; Auxiliary Hook: 2t~80t | Main and auxiliary hooks can operate collaboratively or independently, meeting the needs for switching between light and heavy loads. |
| Span | 10m~35m | Large span solutions can be customized according to site width. |
| Lifting Height | Main Hook: 10m~30m; Auxiliary Hook: 12m~32m | Suitable for outdoor high stacking, high-altitude installation, and other scenarios. |
| Working Class | A5~A7 | Meets the working conditions requirements for frequent outdoor operations and heavy loads. |
| Lifting Speed | Main Hook 0.5~10 m/min; Auxiliary Hook 2~18 m/min (Variable frequency speed control, precise fine-tuning available) |
| Crane Traveling Speed | 10~30 m/min (Windproof and anti-slip design, stable operation in rainy/snowy weather) |
| rolley Traveling Speed | 5~20 m/min (Double-girder structure, smooth and stable trolley operation) |
🛠️ Main and Auxiliary Double Hooks, Double Efficiency at Your Fingertips
The double girder structure combined with the main and auxiliary double hook design breaks the limitations of single-hook operation: the main hook stably carries heavy goods, while the auxiliary hook cooperates synchronously for loading and unloading, enabling "one lift and one standby" or "collaborative lifting," significantly improving loading and unloading efficiency. Whether it's the bulk transfer of steel and building materials or the precise docking of wind turbine towers, flexible switching between light and heavy loads makes every lift more efficient.
🎮 Wireless Remote Control, Unlocking a New Outdoor Operation Experience
Free from cable constraints, the wireless remote control system allows for greater operational freedom. Operators can flexibly control the entire process of lifting, luffing, and traveling from a safe distance, with an unobstructed view, accurately responding to complex outdoor terrain and unexpected situations. No need to climb into the cab or be limited to a fixed operating position, ensuring personnel safety and making large-span, high-altitude operations more convenient.
🌬️ Outdoor-Specific Configuration, Fearless of Wind and Sun
Tailor-made for harsh outdoor environments: the main beam uses wear-resistant and corrosion-resistant steel, treated with sandblasting and epoxy zinc-rich paint for enhanced weather resistance; windproof rail clamps and anchoring devices effectively resist sudden gusts of wind; the sealed electrical box with waterproof connectors is impervious to rain, ensuring stable operation even in high temperatures, heavy rain, and dusty weather, providing robust protection for all-weather operations.
From the rapid turnover of containers in ports to the bulk loading and unloading of raw materials in steel mills, from the transfer of goods in railway freight yards to the installation of wind turbine towers in wind power bases, this double girder gantry crane adapts to all outdoor operation needs with its robust performance. We offer customized design services, tailored to your site dimensions, load requirements, and operating frequency. We also provide 24-hour after-sales support to ensure worry-free operation of your equipment. 🔹 Basic Core Parameters
