Telescoping Bridge Crane | Underhung & Toprunning Options

Product Description

Limited by building column grids and runway spans, traditional bridge cranes fall short when trying to reach dead zones like behind columns or into adjacent bays. Kunfeng Crane offers telescopic bridge cranes as a practical solution to expand hook coverage without structural modifications. These cranes effortlessly bypass architectural obstacles, granting direct access to previously unreachable areas for maximum operational flexibility.

Profile Options for Telescopic Structures: I-Beam vs. G-rail Enclosed Track Systems

When designing telescopic bridges, selecting the right profile type is crucial for balancing load capacity and operational smoothness. There are two primary options commonly used in the industry:

Telescopic I-Beam Design and Structural Integration: I-beams operate in unison to telescope outward and retract, while the crane's primary framework cleverly doubles as the runways. This open-profile design relies on structural rigidity to manage extended reaches, integrating the load-bearing frame directly into the motion path.

Lightweight G-rail Enclosed Track Systems: Suspended from two trolleys on a primary lightweight crane, the G-Rail telescoping bridge features a retractable design. When a transfer unit needs to pass through, the bridge retracts out of the path. This flexible retraction capability effectively eliminates deadlocks and spatial conflicts, ensuring smooth, interference-free coordination between multiple material handling systems in the same workspace. For standard configurations, this technology integrates seamlessly with our KBK steel light bridge crane systems.
