Robust Construction and Simple Installation
Our crane wheel blocks are built to be both strong and adaptable. The modular design gives you versatile connection options, making the installation process simple for your specific machinery.
They are manufactured from high-quality materials like forged steel and cast steel, which undergo heat treatment to ensure durability. With such robust construction, they can reliably handle heavy loads in demanding industrial environments.
Designed for Smooth and Efficient Operation
These wheel block systems are all about providing a smooth and efficient operation. Every part, from the axle to the encapsulated bearings, is precisely engineered for optimal performance.
The direct drive motor provides precise control and precise positioning during movement. This improves the overall safety and operational efficiency of your crane operations, all with a minimum maintenance requirement.

Frequently Asked Questions
What is the difference between forged steel and cast steel wheels?
Cast steel is made by pouring molten steel into a mold, making it a strong and cost-effective choice. Forged steel is shaped under extreme pressure, which aligns the grain of the material and results in a wheel with even greater strength and resistance to wear.
Can these wheel blocks be used on both an overhead crane and gantry cranes?
Yes. Their modular design and various connection options make them a perfect fit for the end carriages on a wide range of equipment, including both overhead crane and gantry cranes of different sizes.
What are the benefits of the encapsulated bearings?
The encapsulated bearings are sealed to keep necessary lubrication in and contaminants like dust and moisture out. This design feature is key to their high reliability, reduces maintenance needs, and helps ensure a long service life.
How do I choose the correct wheel diameter for my load?
The wheel diameter directly relates to the wheel loads it can support. A larger crane wheel has a wider contact surface with the rail, which helps distribute the load more effectively and is important when you need to handle heavy loads.
What does the "direct drive via a splined shaft" feature mean?
This means the motor connects directly to the axle of the crane wheel, eliminating the need for open gears. This is a more reliable and efficient system that provides better speed control and has fewer parts that can wear out.
Do you sell these as single components or only as a full assembly?
While our wheel block systems offer a complete solution, we can also supply single components. You can order a replacement crane wheel, bearings, or a drive motor as needed for your equipment.
Are guide rollers necessary for all crane operations?
Guide rollers are small wheels mounted horizontally. They are not always needed, but they are very useful for keeping the crane in perfect alignment on the track, especially in high-speed applications or on very long runways.
What kind of heat treatment is used on the wheels?
The running surface and inner flanges of the wheels undergo a special heat treatment process. This hardens the steel, making it highly resistant to wear and pressure, which is critical for durability and safety.
What makes this a "low maintenance" system?
The minimum maintenance requirement comes from the smart design. With sealed bearings that don't need frequent lubrication, no open gears to maintain, and the use of high-quality materials, the whole assembly is built for performance with less downtime.
How do these wheel systems contribute to operational efficiency?
They improve operational efficiency by ensuring the reliable and smooth movement of heavy loads. The precise control over operation reduces cycle times, the durability means less downtime for repairs, and the smooth performance protects both the crane structure and the rails from excess wear.
