Quenched Alloy Steel Crane Wheels for Container Terminals
Quenched alloy steel crane wheels are specifically engineered to withstand the extreme operational demands of container terminals. Forged from premium alloy steels such as 42CrMo4 and 65Mn, and treated through quenching and tempering, these wheels deliver superior hardness, wear resistance, and fatigue strength, ensuring long service life under heavy loads and continuous operation.
Key Features:
High surface hardness with a tough core for excellent load-bearing capacity.
Outstanding wear resistance to minimize rail and wheel damage.
Precision forging and machining ensure dimensional accuracy and smooth rolling performance.
Heat treatment optimized for impact resistance and extended operational life in demanding port environments.
Applications:
These quenched alloy steel crane wheels are widely used in gantry cranes, rail-mounted container cranes, ship-to-shore cranes, and other heavy lifting equipment in container terminals. Their durability and reliability guarantee safe, efficient cargo handling in 24/7 port operations.
| Item | Details (Quenched Alloy Steel Crane Wheels – Container Terminals) |
|---|---|
| Material | 42CrMo4, 65Mn, or customized alloy steels – optimized through quenching and tempering to achieve high surface hardness with a tough, impact-resistant core. |
| Forging Capability | Hydraulic Hammers: 5T / 8T / 12T – Support forging of medium to large crane wheels with excellent grain flow and internal compactness. |
| Main Application | Designed for container terminals, including rail-mounted gantry cranes, ship-to-shore cranes, and yard cranes, where heavy loads and continuous operation require exceptional durability. |
| Production Process | Forging → Quenching & Tempering → Rough Machining → Final Machining (if required) – Ensures hardness, wear resistance, and precise dimensional control. |
| Deformation Ratio | Forging Ratio ≥ 3.5 – Strengthens fiber structure, improves fatigue performance, and extends wheel service life under rolling and impact loads. |
| Delivery State | Supplied quenched and tempered, available as rough-machined blanks or fully finished wheels with stress relief to guarantee service stability. |
| Inspection Tools | Equipped with spectrometer, ultrasonic flaw detection, hardness testing, tensile & impact testers, dimensional gauges, and crack detection to ensure zero-defect performance. |
| Service Package | We provide complete solutions from forging, quenching & tempering, machining, inspection, to custom export packing and sea freight logistics — tailored to port crane operators’ specifications and international quality standards. |
The steel forgings production flow:
Material inspection → unloading → quality check → preheating → forging → heat treatment → intermediate inspection → rough machining → NDT testing → final inspection → packing → delivery.
Frequently Asked Questions (FAQs)
Q1: What size range of forgings can you produce?
We are capable of manufacturing forgings weighing from about 100 kilograms up to 7,000 kilograms, making them suitable for medium-duty applications as well as very large industrial machinery.
Q2: Do you provide heat treatment and machining options?
Yes. All major heat treatment processes are carried out in-house, and we can deliver parts either in rough-machined form or as fully finished components using advanced CNC machining to meet customer drawings.
Q3: What industries typically use your products?
Our forgings are widely applied in wind energy, port cranes and material handling systems, heavy construction and mining equipment, and high-performance power transmission assemblies.
Q4: How long does it usually take to complete an order?
For standard inventory products: about 30 days
For tailor-made forgings: usually 40–45 days, depending on dimensions, material, and processing requirements
Q5: Where are you located?
Our facility is situated in Changzhou, Jiangsu Province, close to Shanghai. This location allows us to ship efficiently through Shanghai Port to customers worldwide.
