Dual Trolley System:
Two trolleys operate independently or in tandem, enabling handling of long materials (e.g., pipes, steel beams) or separate loads simultaneously.
Lifting Capacity: 2.5+2.5 tons to 200+200 tons (combined capacity up to 400 tons).
Double Girder Structure:
Box welded girders (Q235B/Q345B steel) ensure rigidity and stability for spans from 10.5–31.5 meters (extendable to 50 meters for custom designs).
Supports A3–A8 work duty classes (ISO 4301-1), suitable for medium to extreme workloads.
Electric Hoist Performance:
Dual-speed lifting: Adjustable speeds from 0.4–10.7 m/min for precision tasks (e.g., QDX models with variable frequency drives).
Lifting Height: 6–60 meters (adjustable based on application needs).
Safety & Control:
Overload protection, anti-collision systems, and emergency stops.
Operated via pendant, remote, or cabin control for flexibility.

Steel Mills: Transporting coils, slabs, and long steel bars.
Ports & Shipyards: Loading/unloading ship components and oversized cargo.
Manufacturing: Handling machinery parts or structural components in assembly lines.
Logistics: Efficient stacking of long materials (e.g., timber, pipes) in warehouses.
Operational Flexibility:
Trolleys can lift loads horizontally and vertically, reducing manual intervention for balancing.
Space Optimization:
Double girder design maximizes vertical clearance while supporting heavy loads.
Safety Compliance:
Meets FEM/DIN/ISO standards with fail-safe brakes, thermal motor protection, and anti-collision systems.
Cost Efficiency:
Modular components and low maintenance reduce operational costs.
The Double Trolley Electric Hoist Double Girder Overhead Crane is ideal for industries requiring precise, high-capacity handling of oversized or complex loads. Its dual-trolley system and robust design ensure efficiency and safety in demanding environments like steel mills, ports, and logistics hubs. For tailored solutions, consult manufacturers like EOT Crane Kit or Tavol Group for configurations matching specific operational needs.
