Overview of Rolling Bridge Cranes

What is a Rolling Bridge Crane? A rolling bridge crane, commonly known as an overhead rolling crane or movable overhead crane, is a robust material handling device utilized in industrial settings. It operates by spanning the width of a workspace via elevated runways, utilizing a bridge that moves horizontally along the designated path. This bridge supports a hoist mechanism, enabling the lifting, movement, and precise positioning of heavy loads with ease and accuracy.

Components and Structure

• Bridge: The primary structural component of a rolling bridge crane, the bridge, is the horizontal beam that spans the width of the workspace. It travels along elevated runways using wheels or tracks attached to the crane runway beams.
• Hoist Mechanism: Mounted on the bridge, the hoist mechanism comprises a lifting hook or other load-bearing attachment. It utilizes ropes or chains wound around a drum to hoist and lower loads.
• End Trucks: These components are found at both ends of the bridge and house the wheels or tracks that allow movement along the runways.
• Runway Beams: Elevated tracks or beams serve as the path for the bridge to move horizontally within the workspace. They provide support and stability for the entire system.
• Controls: Rolling bridge cranes are operated using control panels or consoles. These controls manage the movement, lifting, and positioning of loads, ensuring precision and safety during operations.
