Double Girder & Double Hook: Efficient Partners for Heavy-Duty Scenarios
Adopting a box-type double main girder structure, it boasts stronger rigidity and superior resistance to torsional deformation, easily handling heavy-duty lifting needs with a 160t main hook + 50t auxiliary hook. The coordinated operation of the main and auxiliary hooks enables precise coordination of "main hook lifting weight, auxiliary hook leveling," and also allows for the simultaneous lifting of two materials with different loads, significantly improving workshop lifting efficiency. For scenarios involving high-temperature steel coils in hot rolling mills and large components in heavy industry, the uniform stress design of the double-beam structure effectively reduces the risk of main beam wear and deformation, ensuring long-term stable equipment operation.
Wireless remote control for flexible operation in complex conditions: Equipped with an industrial-grade wireless remote control system, the remote controller has an IP65 dustproof and waterproof rating, suitable for complex environments with high temperatures and dust levels in workshops, with an effective remote control distance of over 100 meters. Operators can perform full-function control of lifting, luffing, traveling, and speed adjustment within a safe field of vision, eliminating the limitations of blind spots in the cab; the micro-motion control function achieves millimeter-level positioning, allowing precise docking of hundreds of tons of steel coils with the transfer flatcar, reducing the time cost and safety hazards of manual alignment.
Multi-dimensional protection, a safety barrier for heavy-duty hoisting
Built-in multiple safety protection systems: Both main and auxiliary hooks are equipped with overload protection devices, automatically alarming and cutting off the operation when the load exceeds the limit; physical stops and limit switches are installed at both ends of the track, providing double limit protection to prevent derailment; laser anti-collision sensors monitor surrounding obstacles in real time, automatically slowing down when too close; dual control modes of cab and remote control, combined with a high-definition monitoring system, enable full visibility and control of the hoisting process, building a solid safety barrier for personnel and equipment.
From steel coils rolling off the production line in the hot rolling mill to equipment assembly in heavy industry bases, and tower transfer in energy projects, this industrial double-girder bridge crane, with its robust performance of "stability, accuracy, and strength," has become an indispensable hoisting core in heavy manufacturing scenarios, laying a solid foundation for enterprises to reduce costs, increase efficiency, and upgrade safety.
