Product Range
Overhead Traveling Cranes (EOT Cranes)
Single Girder Overhead Cranes: Capacity up to 20 Tons, Spans up to 31.5 m. Low-headroom designs using European-type hoists to maximize hook approach and clear ceiling heights.
Double Girder Overhead Cranes: Capacity up to 500+ Tons, Spans up to 40 m. Duty rating up to FEM 5m / ISO A8 for high-frequency steel mill, foundry, and turbine hall operations.
Gantry Cranes
Full Gantry Cranes: Single or double girder, box type or truss type. Fitted with storm anchors, wind-speed monitors, and rail clamp locks for outdoor storage yards and ports.
Semi-Gantry Cranes: One leg runs on an elevated runway beam while the opposite runs on floor rails, saving floor space in dual-bay workshops.
Jib Cranes & Hoist Units
Wall-Mounted & Pillar Jib Cranes: Lifting capacities from 0.5 t to 10 t, rotation angles up to 360 deg. Equipped with electric chain or wire rope hoists for localized workstation handling.
Custom Crane Components & Hoists: End carriages, wheel blocks, drum assemblies, and wire rope hoists available as OEM modular kits.

Technical Applications
Steel Mills & Foundries
High-ambient temperature double girder cranes equipped with insulated ladle hooks, heat shields, and dual motor drives (Duty class FEM 4m/5m).
Heavy Equipment Fabrication
Precise inching control via Variable Frequency Drives (VFD) for mold positioning, alignment, and sub-assembly joining.
Power Plants & Hydro Installations
High-lift double girder gantry and overhead cranes for turbine maintenance, stator lowering, and valve gate operation.
Warehouse & Outdoor Logistics Yards
Rail-mounted gantry cranes fitted with automated grab attachments, container spreaders, or lifting magnets for continuous material transfer.
Structural Modifications: Box girder, truss structure, or compact low-headroom profile to fit existing building clear heights without structural renovation.
Drive & Speed Control: Schneider/ABB Inverter drives for 0.1 m/min precision micro-speed positioning; dual-speed squirrel-cage motors for standard applications.
Safety Interlocks & Monitoring:
Overload limiters with digital LED readouts.
Laser anti-collision sensors for multi-crane runways.
PLC-based fault diagnosis systems with real-time operational logging.
Environmental Treatments: Anti-corrosion C4/C5 marine epoxy paint systems, IP65 stainless steel control panels, and galvanization for high-humidity or corrosive atmospheres.
Structural Fabrication Standards: Submerged arc welding (SAW) on main box girders. Non-Destructive Testing (NDT) via Radiographic (RT) or Ultrasonic Testing (UT) per EN ISO 17640 applied to critical butt welds.
Deflection Ratio: Main girder deflection controlled strictly within 1/800 to 1/1000 of the span under full static load test.
International Certifications: Manufactured in accordance with ISO 9001:2015, ISO 14001, CE Directive 2006/42/EC (Machinery), EN 1090 structural steel execution, and FEM/CMAA design criteria.
Factory Acceptance Testing (FAT): Every unit undergoes 125 percent dynamic and static load testing prior to disassembly and shipment. Test reports and material mill certificates (EN 10204 3.1) are dispatched with project documentation.
Export Packaging, Logistics & Field Support
Export Packing Execution
Main girders are sectioned for standard 40ft OT/FR containers or shipped as breakbulk with marine-grade waterproof tarpaulin wrapping. Electrical cubicles and hoists are vacuum-sealed in fumigated wooden cases.
Documentation Suite
Structural load calculations, Foundation loading diagrams, Electrical schematic drawings, Maintenance manuals (EN), and Inspection Certificates.
On-Site Service
Turnkey installation supervision, runway alignment calibration, commissioning assistance, and overseas technical technician deployment upon request.
