Crane rail clips are essential fastening components used to secure crane and heavy equipment rails to their supporting structures, ensuring operational safety and stability under high load and high-frequency conditions. Based on the installation method, GNEE RAIL offers two primary types of crane rail clips: Bolted Crane Rail Clips and Welded Crane Rail Clips. These clips feature excellent flexibility, adaptability, and durability, and are widely applied in industrial environments such as ports, steel mills, and mining facilities.
1. Bolted Crane Rail Clip
Bolted crane rail clips utilize bolts as the core fastening elements. With advantages such as ease of installation and maintenance flexibility, they are commonly used in various crane rail systems. These clips consist of a base, upper cover, wear-resistant axle, and related fasteners that work together to lock the rail securely onto the foundation. This ensures reliable load-bearing while also allowing convenient future disassembly and adjustments.
Key Advantages & Application Scenarios:
GNEE RAIL's bolted crane rail clips are versatility and adaptability:
Easy Installation & Maintenance: No welding is required; installation is completed via bolting. This allows for simple disassembly, repositioning, or replacement-ideal for temporary rail systems such as construction tracks or mobile crane installations.
Reliable Performance: Wear-resistant axles made from NM360 or NM400 steel reduce frictional loss between the clip and rail. Corrosion-resistant coatings such as hot-dip galvanizing and painting make these clips suitable for harsh environments like high-humidity ports and dusty steel plants.
Balanced Load Capacity: While slightly lower than welded types, bolted clips can still handle 120–180 kN loads, making them suitable for overhead cranes, gantry cranes, and high-frequency applications in steelworks, warehouses, and mining.
Structure & Material Specifications:
Bolted crane rail clips typically consist of seven components:
Base Plate: Provides stable support and anchors the rail to the foundation.
Upper Cover: Holds and protects the rail, enhancing clamping force.
Wear-Resistant Axle: Distributes rail load and reduces friction wear.
Flat Washer: Increases the contact area of the bolt, dispersing stress.
Bolt & Nut: Deliver fastening force.
Shims & Adjustment Pads: Used to fine-tune rail height and level alignment.
GNEE RAIL uses high-quality materials to ensure smooth crane operations. Axles are made from NM360 or NM400 wear-resistant steel; base plates, covers, and pads are available in Q235, Q345 carbon steel or 40Cr, 45# high-strength steel. Stainless steel options (304, 316) are available for enhanced corrosion resistance.
2. Welded Crane Rail Clip
For applications with extreme loads, high stress, and harsh environments, GNEE RAIL offers welded crane rail clips designed for rigid, permanent attachment. These clips are welded directly to the foundation (concrete beams or steel girders), providing unmatched stability and long-term reliability-ideal for heavy-duty equipment.
Key Advantages & Application Scenarios:
GNEE RAIL's welded rail clips are designed for strength and durability:
Maximum Stability: Welding eliminates bolt-loosening risks and allows the clips to handle high dynamic loads-ideal for port gantry cranes, mining operations, and continuous-duty setups.
Low Maintenance Requirements: With no mechanical fasteners to wear out, these clips require less frequent servicing over their lifespan-perfect for heavy-duty systems.
Shock Absorption & Noise Reduction: The rigid connection reduces rail vibrations, which lowers wear on equipment and suppresses operational noise-especially beneficial in high-temperature environments such as foundries or steel plants.
Structure & Material Specifications:
Welded crane rail clips have a simplified four-part structure:
Base Plate: Welded to the foundation, providing stable support.
Upper Cover: Secures and reinforces the rail position.
Wear-Resistant Axle: Distributes loading and minimizes wear.
Weld Joints: The core connection ensuring overall rigidity.
Wear-resistant axles are made from NM360 or NM400 steel. Other components can be made from 40Cr, 45# carbon steel, or high-strength NM-series steel to balance mechanical strength and corrosion resistance.
