The MG Type Double-Girder Gantry Crane is a heavy-duty lifting solution designed for efficient material handling in outdoor and large-span applications, such as freight yards, construction sites, ports, and steel fabrication facilities. Featuring a robust double-girder main bridge with a box-shaped welded steel structure, this crane ensures exceptional rigidity, stability, and load-bearing capacity, making it ideal for lifting loads ranging from 5 to 200 tons (or higher, customizable to requirements).
The MG Series excels in handling bulk materials, containers, steel coils, and prefabricated components, offering versatility across industries. Its ergonomic control options-pendant, radio remote, or cabin-operated-ensure user-friendly operation, while low-maintenance components maximize uptime. Suitable for both indoor workshops and harsh outdoor conditions, this crane is engineered to optimize productivity and safety in demanding lifting operations.
Features of MG type double girder gantry crane:
High stability and reliability, suitable for large-span and heavy-load operations.
Flexible operation modes including ground control, cabin control (enclosed or open type), and remote control. The cabin is equipped with rainproof devices, with optional accessories such as air conditioning and intercom systems.
Wide operating temperature range (-25℃ to +40℃), adaptable to high-humidity environments (≤85% RH) and altitudes ≤2000 meters.
Multi-layered safety systems including:
1. Overload alarm
2. Anti-hook collision protection
3. Phase-failure and overcurrent protection
4. Automatic limit stop devices.
Customizable designs to meet diverse operational requirements.
Application scenarios of MG type double girder gantry crane:
Large-scale outdoor material handling:
Widely used for bulk cargo and container handling at port terminals, railway freight stations, open-air warehouses, and storage yards, particularly in areas lacking fixed support columns.
Specialized material handling:
Compatible with electromagnetic chucks, grab buckets, and specialized lifting tools, extending applications to steel mills and cement product facilities for handling unique materials.
Alternative to overhead cranes:
Preferred solution for indoor/outdoor environments (e.g., workshops, construction sites) where overhead cranes cannot be installed due to absence of corbels or support columns.
-
Main Girder Typically constructed with box girder or truss girder structures, welded from high-strength steel plates (e.g., Q235B, Q345B). -
Legs Rigid legs provide strong load-bearing capacity, while flexible legs adapt to uneven tracks, working together to maintain stable span alignment. -
Trolley Driven by variable frequency motors, equipped with brakes and limit switches, ensuring smooth operation and precise positioning. -
Operator Cab Designed as a fully enclosed structure with air conditioning, anti-vibration seats, and a control console (handles, buttons, display screens). -
Lifting Hook Forged from alloy steel and heat-treated, featuring high toughness and fatigue resistance. -
Wheels Made of cast steel or alloy steel, offering high pressure resistance and wear resistance.
