New Types Heavy Duty Double Girder Overhead CraneCategory—General Industrial Crane
The MGB double-girder semi-girder semi-gantry crane is engineered for versatile material handling in facilities where full gantry movement is restricted. Its unique structural design features one leg traveling on ground-mounted rails, while the opposite side moves smoothly along elevated runway tracks installed on the existing workshop structure.
Core Structure & Operational Mechanism
Robust Double-Girder Framework: Constructed from high-grade Q235B/Q345B steel plates, the main girders are formed with seamless CNC-cut fabrication for uniform strength and extended service life.
Asymmetric Gantry Design: The crane’s single-leg configuration optimizes floor space utilization, allowing seamless integration with building columns and maximizing lateral workspace.
Precision Hoisting System: Equipped with a heavy-duty hook assembly that rotates on thrust bearings, combined with drop-forged lifting hooks and protected wire rope sheathing for secure load engagement.
Advanced Mobility System: Custom-engineered wheels manufactured through vacuum casting technology ensure stable movement along both ground and overhead rail paths, reducing wear and operational vibration.
Intelligent Control & Safety Integration
Operators benefit from multiple control options, including pendant stations and customizable wireless remote systems (F21/F23/F24 series) with speed variation capabilities. The integrated safety suite features:
Multi-directional overload protection with automatic cutoff
Phase failure detection and self-diagnosing circuit monitoring
Anti-collision barriers with dual audio-visual alarms
Weatherproofed components for outdoor applications
Automatic rail clamping systems for parked stability
Human-Centered Operation
The standardized operator cabin provides an ergonomic working environment with vibration-dampening seating, impact-resistant glazing, and optional climate control. All critical functions are accessible through intuitive controls while maintaining clear sightlines to lifting operations.
Technical Excellence in Components
Lifting Mechanism: F-class insulation hoists with precision-machined reducers and dual-speed options
Structural Protection: Triple-layer epoxy zinc-rich coating prevents corrosion in demanding environments
Load Management: Certified overload limiters integrated with drum and motor assemblies
Global Engineering Heritage
As an industry leader from China's primary crane manufacturing region, our facility combines advanced production capabilities with rigorous quality assurance. With documented exports across six continents and annual production exceeding 4,000 gantry systems, we maintain our position through continuous innovation and commitment to engineering excellence. All equipment undergoes comprehensive testing and conforms to international safety standards, supported by 120+ industry certifications including national high-tech enterprise recognition.
The BMG series double girder semi-gantry crane delivers adaptable material handling capabilities where conventional overhead cranes cannot operate. Its hybrid structure enables seamless transitions between indoor and outdoor applications, providing exceptional versatility across multiple sectors.
Industrial Manufacturing & Assembly Lines
Supports just-in-time production by transferring heavy components between adjacent workstations
Enables precision positioning of machinery during assembly processes with controlled lifting speeds
Facilitates die changes and equipment maintenance in manufacturing cells with limited headroom
Logistics & Distribution Operations
Streamlines cross-docking operations where loading areas connect to covered storage facilities
Handles palletized goods and containerized materials moving between warehouse and yard storage
Reduces transit times for mixed-load handling without requiring transfer between different crane systems
Construction Material Processing Yards
Manages structural steel and prefabricated elements in fabrication yards with partial sheltering
Transfers concrete elements and building materials from production areas to temporary storage
Supports modular construction projects where components are assembled then moved to staging areas
Port Infrastructure & Intermodal Facilities
Serves smaller wharves and inland ports with space constraints for full gantry systems
Handles break-bulk cargo transfer between vessels and adjacent covered storage sheds
Maintains operation during adverse weather conditions thanks to the sheltered portion of its run
Infrastructure Maintenance & Repair Centers
Assists in railway maintenance depots for handling traction motors and bogie assemblies
Supports utility service centers in managing transformers and switchgear components
Enables repair operations for mining and agricultural equipment requiring partial enclosure
Specialized Industrial Applications
Processes oversized components in fabrication shops with doorway access limitations
Manages raw material flow in recycling operations between outdoor stockpiles and processing lines
Handles specialized cargo in freight terminals with mixed indoor-outdoor operational requirements
This crane configuration eliminates the traditional boundary between enclosed and outdoor material handling, creating continuous workflow where other systems would require costly transfers or redundant equipment. The asymmetric design provides structural advantages in facilities with existing support columns or limited foundation preparation capabilities.
