Forged Crane Wheel For Overhead Crane Trolley Running Mechanism Components

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 Features

• High-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.

Applications

• Overhead 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

Steel Forgings Production Flow

Raw material verification → careful unloading and organized storage → comprehensive quality assessment → controlled preheating to optimal forging temperature → precision open-die or closed-die forging → performance-enhancing heat treatment (quenching and tempering) → in-process inspection for structural integrity → preliminary machining as required → non-destructive testing (NDT) to detect internal and surface defects → final dimensional and quality inspection → protective packaging → shipment to customer.

Frequently Asked Questions (FAQs)

Q1: What is the size and weight range of your forged components?
We manufacture forgings ranging from approximately 100 kg up to 7,000 kg, accommodating both medium-scale machinery and large industrial equipment that require precise dimensions and high structural integrity.

Q2: Do you offer in-house heat treatment and machining services?
Absolutely. All heat treatment operations are performed internally, and we provide components either as rough-machined blanks or fully finished parts. Advanced CNC machining ensures that each component meets exact customer specifications.

Q3: Which industries commonly utilize your forged products?
Our forgings are extensively used in wind power, overhead and gantry cranes, material handling systems, heavy construction machinery, mining equipment, and high-performance power transmission assemblies.

Q4: What are the typical production lead times?

• Standard or stocked items: generally around 30 days

• Custom or non-standard forgings: typically 40–45 days, depending on material, size, and complexity of machining or heat treatment requirements

Q5: Where is your manufacturing facility located?
Our factory is based in Changzhou, Jiangsu Province, China, conveniently near Shanghai. This strategic location ensures smooth logistics and efficient export handling via Shanghai Port for international deliveries.
