Double-girder gantry crane | The ultimate choice for heavy-duty outdoor operations
In outdoor work scenarios such as ports, open storage yards, and road and bridge construction, ordinary lifting equipment often falls short in the face of strong winds, intense sunlight, and frequent heavy loads. This double-girder gantry crane, with its robust configuration of cable reel power supply and main and auxiliary hooks, coupled with thoughtful designs such as maintenance ladders and sun and rain protection covers, becomes a reliable partner for heavy-duty outdoor handling.

✅ Core robust configuration, solving pain points in outdoor operations
🔧 Double-girder structure + cable reel power supply: Stable and uninterrupted operation
Adopting a box-type double-girder main beam design, it has a stronger load-bearing capacity and is suitable for heavy-duty lifting needs of 50-300 tons; the cable reel power supply system eliminates the constraints of external power sources, automatically retracting and extending the cable during track movement, maintaining stable power even during long-distance outdoor operations, and is not afraid of complex wiring scenarios.
🎯 Dual Hooks: Double Efficiency in One Machine
The main hook is responsible for the core lifting of heavy materials (such as containers and precast beams), while the auxiliary hook can simultaneously assist in the transport of lighter goods or precise positioning. This allows for combined "main lifting + fine-tuning" operations without additional equipment, increasing the efficiency of a single unit by over 30%.
☀️ Exclusive Outdoor Protection: Maximum Durability
Sun and Rain Cover: A full-coverage protective structure effectively isolates the equipment from direct sunlight and rain, protecting electrical components and wire ropes from corrosion and aging, extending equipment lifespan by 20%.
Maintenance Ladder + Platform Railing: Equipped with a non-slip ladder and maintenance platform, along with safety railings, making daily maintenance and troubleshooting safer and more convenient, reducing the risks of working at heights.
🌪️ Wind-resistant and Corrosion-resistant Design: Adaptable to Harsh Working Conditions
The main steel structure beams undergo sandblasting and rust removal followed by epoxy zinc-rich paint anti-corrosion treatment, achieving a wind resistance rating of over level 10. This allows for long-term stable operation under complex outdoor conditions such as high temperatures, heavy rain, and sandstorms, eliminating the need for frequent downtime maintenance.
