Gantry crane
MG Rail Mounted Double Girder Gantry Crane (Heavy Duty)

Product Overview
The MG rail‑mounted double girder gantry crane is designed for heavy‑duty outdoor operations in yards, ports, rail terminals, and large construction sites. With rigid double‑box or truss main beams, rail travel, and a steel wire rope winch/trolley, it delivers stable handling under high duty classes. Remote and cabin controls, matched rails, and industrial‑grade electrics ensure precise, efficient, and safe lifting in demanding environments.
Product Advantages
Heavy‑Duty Rail‑Mounted Structure
Double‑girder design on fixed rails provides high rigidity, smooth long travel, and excellent stability for frequent lifting cycles.
Wide Working Envelope
Typical spans from 18–35 m with long travel on rails; supports A‑/U‑type frames and optional cantilever to increase working coverage.
Operator‑Focused Controls
Remote and cabin control configurations with insulated flooring, tempered glass, and safety accessories for long‑shift comfort and safety.
Industrial‑Grade Components
Q235/Q345 steel, shot‑blasted Sa2.5, epoxy zinc‑rich painting; electrics from CHINT/Siemens/Schneider; conductor via cable reel or busbar.
Documentation & Warranty
Machinery test report/inspection per listing, 1‑year warranty, and technical support for reliable lifecycle operation.
Application Scenarios
Open‑air warehouses and material yards
Precast and steel fabrication yards
Ports and rail freight stations
