Industrial & Crane Rail Track Solutions
GNEE RAIL supplies crane rail fastening components for container terminals, shipyards, steel mills, industrial plants, and automated warehouse systems. The product range includes crane rail clamps, baseplates, continuous sole plates, rail pads, anchor bolts, weldable shoulders, and related fixing hardware.
Crane runway systems differ from conventional railway tracks because the rail is usually installed on a steel girder, concrete runway beam, or another fixed industrial structure. Selection therefore depends on more than the rail profile. Wheel load, rail base width, support structure, clamp spacing, fixing method, and required lateral adjustment all affect the fastening arrangement.
Crane Runway Installation Conditions
Crane and industrial rail systems can be installed on steel girders, concrete runway beams, or other engineered support structures. The fastening arrangement changes with the foundation and the way the rail is adjusted or fixed.
Several factors normally need to be checked before selecting the components:
Concentrated Wheel Loading: Crane wheels transfer loads through relatively small contact areas. The rail support and baseplate arrangement therefore needs to match the specified wheel load and supporting structure.
Lateral Wheel Forces: Skewing, braking, acceleration, and crane travel can generate transverse forces at the rail. Clamp geometry and fixing strength are selected according to the required lateral restraint.
Rail Alignment: Crane runways generally require controlled rail gauge, straightness, and elevation. Adjustable clamps, slotted mounting holes, shims, or other adjustment features can be used where the runway design requires them.
Support Arrangement: Some systems use continuous steel sole plates below the rail, while others use individual baseplates or discrete fastening points.
Components for Crane and Industrial Rail Systems
The fastening arrangement can be supplied as a complete system or as individual components for installation, replacement, and runway maintenance.
Adjustable Crane Rail Clamps
Adjustable clamps provide the connection between the crane rail and its supporting structure while allowing the rail position to be set during installation.
• Weldable Clamps: A lower base is welded to the steel girder, with the upper clamp securing the rail flange through a bolt connection.
• Bolted Clamps: The clamp base is fixed with embedded anchor bolts or through-bolts, commonly used with concrete runway structures.
• Adjustable Designs: Slotted holes, clamp geometry, and synthetic or rubber noses can be incorporated where lateral rail adjustment is required.
• Synthetic / Rubber Nose: The elastomer contact element provides a compliant interface between the clamp and rail while accommodating the specified clamping arrangement.
Crane Rail Baseplates and Sole Plates
The supporting plate configuration depends mainly on whether the runway uses discrete or continuous rail support.
• Discontinuous Baseplates: Individual cast QT450-10 or forged steel plates can be installed at specified fastening points beneath the rail.
• Continuous Sole Plates: Steel plates run beneath the rail along the runway and can be supplied with drilled holes corresponding to the supporting girder arrangement.
• Rail Seat Geometry: Flat or formed rail seats can be produced according to the rail profile and approved installation drawing.
Steel-Reinforced Rail Pads
Rail pads are placed between the crane rail and its steel or concrete support.
• Construction: Synthetic rubber such as NBR or EPDM can be combined with an embedded flat steel strip for applications requiring additional resistance to lateral extrusion.
• Material Options: EVA and polyurethane are also available where specified by the application.
• Typical Functions: The pad provides a resilient interface between the rail and support structure and can reduce direct contact, impact transmission, and local surface irregularities.
Crane Rails and Fixing Hardware
Crane rail systems can also be supplied with the associated rail connection and fixing hardware.
• Rail Sections: DIN 536 profiles including A45, A55, A65, A75, A100, A120, and A150; CR73 and CR100; MRS87A, QU70, QU80, QU100, QU120; and selected flat-bottom rail sections.
• Fixing Hardware: Anchor bolts, hook bolts, weldable studs, shims, leveling plates, and related fixing components can be matched to the approved runway design.
Rail Profiles and Installation Parameters
The rail section, wheel load, support structure, fixing method, and adjustment requirements are normally defined together in the crane runway design.
