European Type Single Girder Gantry Crane
Products Description
Key Features of European-Type Single Girder Gantry Cranes:
Single Girder Design
Uses one main beam (typically an I-beam or box girder) for the bridge, making it lighter and more cost-effective than double girder cranes.
Suitable for light to medium-duty lifting (usually up to 20 tons, but can vary based on design).
European-Style Hoist
Equipped with a wire rope hoist or chain hoist (e.g., from brands like Demag, ABUS, or Konecranes).
Smooth and precise lifting with variable speed control options.
Modular & Flexible Structure
Adjustable span, lifting height, and runway length to fit different workspace requirements.
Can be fixed or movable (with end carriages and wheels for rail or floor movement).
High-Quality Materials & Safety
Made from high-grade steel for durability.
Includes safety brakes, overload protection, limit switches, and emergency stop functions.
Power Options
Electric-powered (common for heavy-duty use).
Manual operation (for lighter loads or limited power availability).
Control Systems
Pendant control (wired or wireless).
Radio remote control for safer and more flexible operation.
