Gantry Crane Wheel

Product Introduction

Gantry crane wheels are responsible for bearing the entire load of the crane, including the hoisted materials, and facilitating smooth, безопасный, and efficient longitudinal travel along the defined path. Engineered for extreme durability and performance, these wheels directly impact the crane’s operational safety, longevity, and noise levels. Manufactured from high-strength alloys and subjected to rigorous heat treatment, our gantry crane wheels are designed to withstand immense pressure, shock loads, and abrasive wear in the most demanding industrial environments, from steel mills and shipping ports to heavy fabrication workshops.

Gantry Crane Wheels Key Features

• 1. Exceptional Durability & Wear Resistance

  • Forged from high-carbon steel or alloy steel (НАПРИМЕР., 65Мнжен, 42CRMO), our wheels offer superior tensile strength and hardness.

  • Advanced heat treatment processes like quenching and tempering create a hard, wear-resistant outer surface (rim) while maintaining a tough, shock-absorbing core.

• 2. High Load-Bearing Capacity

  • Precisely engineered to handle static and dynamic loads, ensuring stable performance under the full rated capacity of the crane without deformation.

• 3. Optimized Tread Profile & Flange Design

  • The tread profile is machined to perfectly match the contour of the crane rail (НАПРИМЕР., ARA, KRUPP, flat rail), ensuring maximum contact area and reducing point stress.

  • The flange is designed to provide secure guidance, preventing derailment while minimizing friction and wear against the rail side.

• 4. Прецизионная обработка

  • Each wheel undergoes precision machining and grinding to achieve strict tolerances on diameter, concentricity, and surface finish. This ensures smooth rotation, reduces vibration, and extends the life of both the wheel and the rail.

• 5. Robust Bearing Seats

  • The bore and keyway are accurately machined to ensure a perfect fit with the axle and bearings, guaranteeing efficient power transmission and preventing slippage or premature failure.

• 6. Customization Options

  • We provide fully customizable wheels tailored to your specific requirements, including diameter, width, bore size, flange height, and material grade to suit your unique gantry crane model and application.

Types of Gantry Crane Wheels

Gantry crane wheels are categorized based on their flange type and material/construction.

А. Classification by Flange Type

• 1. Double Flange Wheels:

• • Самый распространенный тип, featuring flanges on both sides of the tread.
  • Приложение: Used on runways with standard rails where positive guidance is required from both sides to prevent derailment. Ideal for straight and slightly curved tracks.

• 2. Single Flange Wheels:

  • Feature a flange on one side only, with the other side being flat.
  • Приложение: Typically used in pairs on a single axle. Often found in crane systems where one side is guided by a rail while the other side runs on a flat surface or to accommodate specific track alignment and thermal expansion.

• 3. Flangeless Wheels:

  • Have no flanges and a flat or slightly convex tread.
  • Приложение: Used in conjunction with separate horizontal guide rollers. Common in large, specialized gantry cranes (НАПРИМЕР., container handling, shipbuilding) where extreme lateral forces are managed independently, allowing for sharper curves and reducing scrubbing.

Беременный. Classification by Material & Строительство

• 1. Forged Steel Wheels:

  • Manufactured through a forging process that aligns the grain structure, resulting in superior strength, impact resistance, and fatigue life. They are the premium choice for heavy-duty and high-cycle applications.

• 2. Cast Steel Wheels:

  • Made by pouring molten steel into a mold. A cost-effective solution for standard-duty applications. The quality is highly dependent on the casting process to avoid internal defects.

• 3. Alloy Steel Wheels:

  • Made from steel alloys like 42CrMo or 65Mn, which provide an excellent balance of high surface hardness and deep toughness after heat treatment. This is the most common and recommended material for industrial gantry cranes.

• 4. Case-Hardened Wheels:

  • Undergo a specific heat treatment (НАПРИМЕР., carburizing) to create an extremely hard, wear-resistant surface layer while retaining a soft, ductile core. Excellent for applications with very high wear and rolling contact fatigue.

Gantry Crane Wheel Manufacturing Process

FAQ: Gantry Crane Wheel

Q1: What is the primary function of a gantry crane wheel?

А: The gantry crane wheel is a fundamental component that serves two main purposes: to support the full weight (нагрузка) of the gantry crane and its lifted materials, and to guide the crane smoothly and safely along the runway rails.

Q2: How often should gantry crane wheels be inspected?

А: We recommend a visual inspection before each shift for signs of wear, трещины, or damage. A formal, detailed inspection should be conducted monthly by a qualified technician. The exact frequency depends on the crane’s duty cycle, load intensity, and operating environment.

Q3: What are the common signs of a failing crane wheel?

А: Common warning signs include:

• 1. Visible Flange Wear: Thinning or mushrooming of the flange.
• 2. Tread Wear: Uneven wear, flat spots, or deep scoring on the tread.
• 3. Abnormal Noise: Grinding, squealing, or rumbling sounds during travel.
• 4. Vibration: Excessive shaking or bumpy movement of the crane.
• 5. Derailment: The wheel frequently jumps off the track.

Q4: How do I choose the right material for my crane wheel?

А: The choice depends on your application’s demands:

• 1. Standard Duty (55# Сталь / C45): Suitable for light to moderate use with lower loads.
• 2. Heavy Duty (65Мнжен): Our most common recommendation, offering an excellent balance of high surface hardness and good toughness for most industrial applications.
• 3. Severe Duty (42CRMO): For extremely high loads, impact, and abrasive environments like steel mills or ports.

Q6: How is the maximum wheel load calculated?

А: The maximum wheel load is a calculated value based on the crane’s total weight, its lifting capacity, the number of wheels, and the load distribution. It is a critical safety parameter. Our engineering team can assist in verifying the required wheel load capacity for your system.
