Stacker Crane Systems 42CrMo Free Forging Forged Trolley Wheel For Port Crane

Forged Trolley Wheel Free Forging for Heavy-Duty Port Crane and Stacker. Systems is a high-strength forged component engineered for repetitive load-bearing and rolling operations in harsh port and industrial environments. Manufactured from premium alloy or carbon steel grades such as 42CrMo4, these wheels are designed for exceptional surface hardness, impact resistance, and fatigue life—ideal for cranes operating under frequent start-stop cycles and lateral stress.

With precision open-die forging and heat treatment processes, each wheel achieves uniform grain structure and dimensional integrity. Forged profiles can include integrated flanges, bores, and customized tread geometries to meet the operational demands of gantry cranes, bridge cranes, RTGs, container stackers, and rail-guided systems.

Key Features:

• Superior fiber grain flow and dense internal structure for enhanced durability

• High surface hardness with a tough core for long service life under heavy loads

• Capable of integral forging of flanges, hubs, and bore sections to ensure concentricity

• Supports various heat treatment options such as normalizing, quenching & tempering, and surface hardening

Common Types:

• Flanged forged wheels for guided rail operations (e.g., RTG and gantry cranes)

• Non-flanged wheels for unguided rolling systems

• Solid or hollow designs, depending on load and weight optimization needs
