Link-Belt LS-98D & LS-108D: Questions Regarding FMC vs. Sumitomo

[MikePhua]

The Link-Belt LS-98D and LS-108D are well-known models in the heavy equipment industry, with both offering strong performance in various construction applications. However, users often have questions regarding certain components of these machines, particularly in relation to whether they are equipped with FMC or Sumitomo parts, especially for the undercarriage and other hydraulic components.
Overview of Link-Belt LS-98D & LS-108D Models
The Link-Belt LS-98D and LS-108D are part of Link-Belt's crawler crane series, known for their robust design and ability to perform under harsh working conditions. These machines are often used in heavy lifting operations and large construction projects. Their reliability is attributed to their engineering and design, which incorporate high-quality components from renowned manufacturers.
FMC vs. Sumitomo: What’s the Difference?
One of the primary points of confusion among owners and operators of Link-Belt LS series cranes is understanding whether certain components, especially in the undercarriage, are sourced from FMC or Sumitomo. Here’s a quick breakdown:

• FMC: FMC Technologies is a well-established name in the manufacturing of hydraulic systems and components. If your Link-Belt crane uses FMC parts, it typically indicates that the crane is equipped with hydraulics designed for heavy-duty performance and reliability. FMC components are known for their precision and longevity, making them ideal for industrial and construction applications.
  
• Sumitomo: Sumitomo is another major player in the heavy equipment industry, known for their high-quality transmissions, motors, and undercarriage components. Sumitomo components tend to be slightly more cost-effective and are often favored in machines that require more affordable parts without sacrificing quality.
  

The confusion comes from the fact that both FMC and Sumitomo have been suppliers to various manufacturers, including Link-Belt. Depending on the machine’s model year or specific configuration, components from either of these manufacturers might be used.
Key Components Affected by FMC vs. Sumitomo
The main difference between these two suppliers is found in the undercarriage and hydraulic systems. Let’s look at where they might impact the performance and maintenance of your machine:

• Undercarriage: The undercarriage on heavy equipment like the LS-98D and LS-108D is crucial for stability and smooth operation. If your crane has Sumitomo undercarriage components, it might be slightly more affordable but still durable enough for most applications. FMC undercarriages, on the other hand, are designed for high performance and long service life, often being more expensive but offering superior durability.
  
• Hydraulics: The hydraulic system is the lifeblood of any crawler crane. FMC hydraulics are typically recognized for their efficiency in high-load situations, making them ideal for heavy-duty lifting. Sumitomo, while still high quality, often provides hydraulic systems that are more geared towards general-purpose applications.
  

What Owners Need to Know

1. Identification of Components: The first step in determining whether your Link-Belt LS-98D or LS-108D is equipped with FMC or Sumitomo components is to check the machine’s serial number and model year. Many owners have found that newer models or specific configurations are equipped with one brand or the other.
   
2. Maintenance Considerations: Maintenance procedures for both FMC and Sumitomo parts are largely similar, but there are differences in terms of part availability and pricing. If your crane uses FMC parts, you may face slightly higher maintenance costs, but the parts tend to last longer under heavy-duty conditions. Sumitomo parts are generally more cost-effective but still offer great performance for most tasks.
   
3. Spare Parts Availability: When ordering spare parts, it’s essential to know whether your machine uses FMC or Sumitomo components. While the parts may look similar, they could differ in terms of performance characteristics and compatibility. Always check your machine’s specific part manual or consult with a dealership to ensure the correct parts are ordered.
   
4. Performance and Longevity: Both manufacturers produce high-quality parts, but the performance longevity may vary. FMC parts are often preferred for extremely heavy lifting applications where reliability and long-term performance are critical. Sumitomo, on the other hand, can be a more budget-friendly choice for routine construction tasks that do not require as much strain on the equipment.
   

Conclusion: Making the Right Choice for Your Link-Belt LS Series
In the end, whether you choose to stick with FMC or Sumitomo components largely depends on your specific needs and budget. If you’re looking for cost-effective yet reliable components for general construction use, Sumitomo parts are a great choice. However, if you require high-performance components for heavy-duty lifting and want to ensure the longest possible lifespan for your undercarriage and hydraulic systems, FMC may be the better option.
Understanding the specific components used in your Link-Belt LS-98D or LS-108D will help you make informed decisions when it comes to maintenance, repairs, and upgrades, ensuring that your crane remains reliable and efficient for years to come.
