Function and Applications
Forged Crane Rail Wheels are critical for guiding rail-mounted cranes along tracks, providing stability and load-bearing capacity under dynamic and static stresses. Their flange design (single or double) ensures precise alignment, preventing derailment and minimizing wear on rail systems. Commonly used in:

· Port Machinery: Powering gantry cranes, quay cranes, and container handling equipment for efficient port logistics.

· Sugar Plants: Supporting rail-mounted cranes and transfer carts handling heavy, abrasive materials.

· Steel Mills: Enabling overhead cranes to transport molten metal or heavy slabs.

· Mining Operations: Facilitating rail-based cranes for ore and equipment transport.

· Heavy Industry: Used in cement plants, shipyards, and manufacturing facilities for bulk material handling.

WALKSON’s crane rail wheels are designed to endure high axial loads (up to 100 tons per wheel), corrosion, and abrasive conditions, reducing downtime and maintenance costs. Contact us at info@walkson.com (mailto:info@walkson.com) to discuss your crane wheel requirements.

Material Grades (EN and ASTM Standards)

WALKSON selects premium forged steel grades to ensure strength, toughness, and resistance to wear and fatigue. Commonly used materials include:

· EN Standards:

· S355J2 (EN 10025): A high-strength, low-alloy steel for general-purpose crane wheels.

· C45E (EN 10083): A medium-carbon steel offering balanced strength and machinability.

· 42CrMo4 (EN 10083): A chromium-molybdenum alloy steel for high-load, wear-resistant applications.

· ASTM Standards:

· AISI 1045 (ASTM A29): Equivalent to C45E, providing excellent toughness for crane wheels.

· AISI 4140 (ASTM A29): Equivalent to 42CrMo4, ideal for high-stress crane applications.

· AISI 4340 (ASTM A29): A high-strength alloy for extreme conditions in port or mining cranes.

Materials are chosen based on load, environmental exposure, and wear requirements. WALKSON provides material certification per EN 10204 3.1 or 3.2 standards, ensuring traceability and compliance.

Modern and Standardized Manufacturing Process

WALKSON employs a state-of-the-art manufacturing process for Forged Crane Rail Wheels, adhering to international standards at every stage:

· Material Sourcing: High-quality steel ingots are sourced from certified suppliers, verified for chemical composition and purity.

· Forging: Hot forging at 1,100–1,250°C using hydraulic presses (up to 10,000 tons) to create a dense, uniform grain structure for superior strength and fatigue resistance.

· Standard: ISO 6892-1 (tensile testing), ASTM E8/E8M.

· Heat Treatment: Normalizing, quenching, and tempering to achieve optimal hardness (HB 229–269 for 42CrMo4) and toughness.

· Standard: EN 10083-3, ASTM A29.

· Machining: CNC lathes and milling machines ensure precise flange profiles, wheel diameters, and surface finishes (Ra 3.2 or better).

· Standard: ISO 2768 (tolerances), ASME Y14.5 (GD&T).

· Surface Treatment: Optional induction hardening (HRC 50–55) or anti-corrosion coatings (e.g., zinc-rich primer) for enhanced durability in corrosive environments.

· Standard: ISO 12944 (corrosion protection).

· Inspection: Comprehensive quality checks using advanced equipment (detailed below).

Our ISO 9001:2015-certified facilities ensure consistent quality and traceability. We comply with EN 13262 (railway wheels, applicable for crane rail systems) and ISO 6506 (hardness testing) for relevant standards.
