Double-girder bridge crane
Double girder overhead crane is high‑performance heavy‑duty lifting equipment. Adopting rigid double box‑girder structure, it features small deflection and stable running. Multiple control ways and safety devices are equipped. Span, lifting height and working class can be customized. It supports OEM and non‑standard design, widely applied in workshops, steel mills, warehouses and other industrial sites for heavy goods lifting and handling.

- High rigidity double‑girder structure, minimal deflection and vibration for continuous heavy‑duty operation
- Flexible load capacity, optional single or dual trolley for long and irregular workpieces handling
- Full set of safety protections including overload limiter, travel limit switches, anti‑collision buffer and dual emergency brakes
- VFD variable frequency drive, smooth start‑stop, low load swing and accurate positioning
- High‑strength steel and premium welding workmanship, excellent anti‑wear and anti‑corrosion performance
- Energy‑efficient design, standardized modular components, easy inspection and low maintenance cost
- Customizable span, lifting height and travelling speed to match different workshop layouts
- Dual control options: operator cabin and wireless remote control for convenient operation
- Support intelligent retrofit with remote monitoring, fault self‑diagnosis for industrial IoT connection
