PRODUCT DESCRIPTION
Comprehensive Introduction to STS Crane Traveling Wheel Sets
I. Basic Structure and Components
The traveling wheel set of an STS (Ship-to-Shore) crane consists of the following core components:
- Wheels: Made of high-load-bearing cast/forged steel (e.g., ZG430-640 or 65Mn alloy), surface-hardened through quenching (hardness HB300-350, hardened depth ≥20mm), designed to support the crane's full load and roll on tracks.
- Drive System: Includes powered driving wheels and passive driven wheels, enabling controlled movement via electric motors or hydraulic systems.
- Structural Components: Integrated axle boxes, bearings (e.g., angular contact bearings), and mounting brackets to ensure stability and lateral force resistance.
II. Key Features and Performance
High Load Capacity
Single-wheel load capacity ranges from 2.75 to 40 tons, with wheel diameters spanning 250-1000mm, tailored for heavy-duty port operations.Dynamic load design optimized via finite element analysis (FEA) to minimize track contact stress and wear.
Environmental Resistance
Saltwater corrosion-resistant coatings (e.g., ceramic coatings) or high-temperature alloys (e.g., 65Mn) ensure durability in humid, saline, and dusty port environments.
Precision Operation
Strict alignment control: vertical deviation ≤1mm, symmetric center error ≤0.07mm, preventing rail-gouging, noise, and abnormal wear.
III. Core Technologies and Innovations
Material and Manufacturing
Forged wheels outperform cast variants in structural density and fatigue resistance;
Polyurethane/nylon composite wheels are used for noise reduction (e.g., lab equipment), while steel wheels dominate port applications.
Smart Monitoring and Maintenance
Integrated vibration sensors and IoT systems enable real-time monitoring of wear, temperature, and lubrication, supporting predictive maintenance.
Modular Design
Rapid-replacement axle boxes and wheel assemblies (e.g., 800mm-diameter wheels with customizable single/double-sided configurations) minimize downtime.
IV. Applications and Maintenance Guidelines
- Typical Applications: Container terminal operations, heavy-load shipboard equipment handling, and high-frequency material transport.
- Maintenance Standards:
- Replacement Threshold: Wheels must be replaced when uniform wear reaches 15-20% or rim wear exceeds 60%;
- Lubrication: Regular application of high-temperature grease to extend bearing life.
V. Customized Solutions
- Parameter Customization: Adjust wheel rim profiles and materials based on track curvature and slope (e.g., widened rims for enhanced grip);
- Special Requirements: Explosion-proof designs or lightweight carbon fiber composite wheels (for energy efficiency) available upon request.
