Double hook coordination for precision and efficiency.
Main and auxiliary double hook configuration: The main hook is responsible for heavy-duty lifting of large tonnage loads, while the auxiliary hook can flexibly assist in light-duty or precise positioning operations. The coordinated operation of the two hooks can meet the lifting needs of tens or even hundreds of tons, while achieving precise positioning and significantly improving operational efficiency.
Stable load-bearing structure: The double-girder main beam design ensures even stress distribution and strong torsional resistance, effectively distributing the load and ensuring structural stability and smooth operation under heavy-duty conditions, eliminating swaying and deviation during lifting.
Reliable Power Supply, Continuous Operation
Cable Reel Power Supply System: Utilizing a professional cable reel power supply system, it automatically retracts and extends cables as the equipment moves, avoiding cable tangling and dragging issues. This ensures continuous power supply during long-distance operations, significantly improving operational continuity.
Adaptable to Complex Conditions: Whether in open-air storage yards, port terminals, or industrial plants, cable reel power supply provides stable and reliable operation in harsh environments, ensuring 24/7 reliable operation.
Convenient Maintenance, Worry-Free Operation
Integrated Maintenance Access: Equipped with a dedicated ladder and maintenance platform, the equipment allows operators safe and convenient access to critical components such as the main beam, trolley, and electrical systems. Daily maintenance and troubleshooting are more efficient, significantly reducing downtime.
Safety Protection Design: Ladders and platforms are equipped with anti-slip pedals and guardrails, meeting industrial safety standards and providing comprehensive safety protection for maintenance personnel, making maintenance work more worry-free.
Wide Range of Applications, Superior Performance
Port Terminals: Efficiently handles the loading, unloading, and transfer of containers and heavy equipment, contributing to the efficient operation of port logistics.
Manufacturing Workshop: Suitable for hoisting and transferring heavy workpieces and large molds, ensuring smooth production line operation.
Logistics Yard: Enables precise scheduling of bulk goods and heavy components, improving warehousing and logistics efficiency.
Choosing our double-girder gantry cranes means choosing an efficient, safe, and reliable heavy-duty hoisting solution, freeing you from tedious and risky heavy-duty operations and providing dual guarantees for your production efficiency and operational safety.
