The Forged Crane Wheel for Overhead Crane Trolley Running Mechanism
Components is engineered for demanding lifting environments where high load
capacity, stable operation, and long service life are essential.
Manufactured from premium alloy steels and produced through
precision open-die forging, each wheel provides exceptional
resistance to wear, deformation, and impact stress. Its refined
grain structure and controlled heat treatment ensure superior
mechanical performance and reliable stability during continuous
trolley movement.
Product FeaturesHigh-Strength Forged Structure: Open-die forged to achieve refined grain flow, providing
excellent load-bearing capability and fatigue resistance. Exceptional Wear Resistance: Special alloy steel composition and controlled quenching and
tempering deliver long-lasting durability under high-frequency
rolling conditions. Precision Machining Accuracy: Machined to tight tolerances to ensure smooth trolley operation,
reduced vibration, and minimal track wear. Custom Profiles Available: Ready for custom groove shapes, hardness zones, or surface
treatments based on specific crane designs. Enhanced Impact Toughness: Optimized heat treatment guarantees stable performance against
sudden load changes and operational shocks.
ApplicationsOverhead Crane Trolley Running Mechanisms in workshops, heavy fabrication plants, and steel mills Industrial Lifting Equipment requiring precise motion control and high load stability Material Handling Systems in production lines, assembly shops, and logistics centers Harsh Operating Environments where durability, reliability, and extended service life are
critical

Mechanism Components) |
|---|
| Material | 42CrMo4, 60Si2Mn, or tailored alloy steels – formulated to deliver
high wear resistance, stable hardness distribution, and strong
impact toughness required for overhead crane trolley travel
systems. | | Forging Capability | Hydraulic hammers and open-die presses: 5T / 8T / 12T – capable of
producing compact, high-strength forged wheels with uniform grain
flow ideal for continuous trolley operation. | | Main Application | Specifically designed for overhead crane trolley running mechanisms, including workshop overhead cranes, steel mill cranes,
gantry-type overhead cranes, and material-handling bridge cranes
where smooth running accuracy and load stability are essential. | | Production Process | Free Forging → Controlled Quenching & Tempering → Rough
Machining → Optional Finish Machining → Stress Relief → Final
Dimensional Inspection — ensuring precision rolling performance and
long service life. | | Deformation Ratio | Forging Ratio ≥ 3.0 – enhances fiber orientation, strengthens the wheel tread and hub
area, and increases fatigue resistance under repeated rolling and
starting/stop cycles. | | Delivery State | Delivered in quenched and tempered condition, available as near-finished wheel blanks or fully machined crane
wheels ready for installation on trolley assemblies. | | Inspection Tools | OES chemical analysis, ultrasonic testing (UT), magnetic particle
testing (MT), hardness testing, tensile & impact tests, and
precision dimensional gauges to ensure stable and defect-free
operation under dynamic loads. | | Service Package | Complete service covering forging, heat treatment, machining, NDT
testing, dimensional control, anti-corrosion packaging, and
logistics arrangements tailored for overhead crane manufacturers
and lifting equipment integrators. |
