Advantages of Crane Wheel Block
Strong Carrying Capacity
Crane wheel blocks must support both the crane's weight and the load being moved, making load-bearing capacity essential. Properly designed wheel blocks ensure stable operation and safety. Most crane wheels are made from high-strength steel, like ZG310-570, to meet load requirements.
Good Control Performance
Well-designed wheel blocks offer smooth travel and precise steering. The wheel's tread shape (cylindrical, conical, or drum) and rim form (double, single, or no rim) affect handling. For European-style crane wheel blocks, a wider tread is preferable for frequent directional changes and improved wear resistance.
High Security
The quality and reliability of the wheel block are vital for crane safety. A good wheel block reduces the risk of breakdowns and accidents, protecting workers and equipment. European-style wheel blocks use high-strength materials and precise processing, enhancing overall strength and durability.
Easy to Repair and Replace
Some crane wheel blocks are designed for easy maintenance. European wheel blocks often use crescent-type or eccentric adjustable bearing seats, making disassembly and assembly simpler, which reduces maintenance time and costs.
Adaptable
Crane wheel block designs consider different working environments. For cranes in wet, corrosive, or high-temperature conditions, special materials and coatings are used to protect the wheel blocks. European wheel blocks are also adaptable to different track types, like square steel tracks, to meet various user needs.

Packaging and Delivery
Choice Of Crane Rail Wheels
Wheel Material: Crane rail wheels are typically made from cast or forged steel, with forged steel offering better durability. Popular grades include AAR M-107, AAR M-208, and AAR M-201, each suited for different applications.
Wheel Diameter: The diameter affects load capacity and wear resistance. Larger wheels distribute the load more evenly, reducing wear and extending service life. Choose a diameter suitable for the crane's capacity and desired service life.
Wheel Flange Design: The flange design is critical for alignment and preventing derailment. Single flange wheels are used with a guide rail, while double flange wheels offer better guidance.
Wheel Tread Profile: The tread profile affects the contact area between the wheel and the rail, influencing wear. Tread profiles can be flat, conical, or dual-radius, depending on the application.
Wheel Hardness: Harder wheels last longer but may cause more rail wear. Balance wheel and rail hardness to minimize maintenance costs.
Bearing Type: Bearings can be plain or roller. Roller bearings offer lower friction and longer life but are more expensive. Plain bearings are cost-effective but need more frequent maintenance.
Lubrication: Proper lubrication reduces wear and extends wheel life. Follow manufacturer recommendations for lubricant type and maintenance intervals.
Manufacturer's Reputation: Choose wheels from a reputable manufacturer known for high-quality products to ensure reliable performance.
FAQ
Q: What is the purpose of a crane block?
A: For example, in construction, crane blocks are used to lift and move heavy loads such as steel beams, concrete blocks, and large equipment. In shipping, crane blocks are used to load and unload heavy cargo from ships, while in manufacturing, they are used to move raw materials and finished products within a factory.
Q: What is a block used in cranes?
A: Hook blocks, often called crane blocks or crane bottom blocks, are below-the-hook crane lifting equipment designed for your specific application. Sheave configuration, capacity, special control requirements and unique reeving patterns can be incorporated to improve your industrial lifting equipment operation.
Q: What is the wear limit for a crane wheel?
A: Wear of contact 50% or less of full size thickness Wear of mechanism To be correctly operated. Wear of wheel contact face 20% or less of full dia.
Q: What is the hardness of a crane wheel?
A: Crane wheels are made of 65Mn/ ZG430-640(CL60)cast steel, and the surface of the crane wheel frequency undergoes the heat treatment and the hardness of crane wheels usually complies with the following: The hardness of tread and inner of wheel flange(HB)≥300～380.
Q: What is the function of crane wheel block?
A: It is an essential component that helps to support the weight of the crane, enabling it to move smoothly and efficiently. The primary function of a crane wheel block is to support the weight of the crane and its load. The blocks are made from high-quality materials that can withstand tremendous forces, ensuring the safety and stability of the crane. Another important function of the crane wheel block is to provide smooth movement for the crane. The wheels rotate on an axle, ensuring that the crane moves smoothly and evenly.
