Top 3 Bottom Loading Arms for Sulfur and LPG Loading Applications

Bottom-loading arms offer several advantages over other types of loading equipment. At Northern Platforms, we carry a complete range of OPW Engineered Systems’ loading arms perfect for sulfur and LPG loading applications.


Below, we will highlight our top three models for sulfur and LPG loading and a bottom loading arm accessory that can make molten sulfur loading safer. Keep reading to find out more! 


Unsupported Boom Bottom Loader

The OPW Unsupported Boom Bottom Loading Arm is designed to provide a flexible, long-range, reliable operation that is easy to use in sulfur and LPG loading operations. This heavy-duty bottom-loading arm has five swivel planes of rotation, allowing for adjustments when changes in elevation or tilting due to the vehicle being loaded or unloaded occur. If you’re looking for a versatile, heavy-duty, and durable bottom-loading arm for your LPG or sulfur-loading applications, the OPW Unsupported Boom Bottom Loader from Northern Platforms has you covered!


Here are a few other features and benefits of this loading arm: 

  • Available in 2″ to 6″ sizes
  • Available in carbon steel, stainless steel and aluminum
  • Fully customizable
  • Can be safely stored in a “jack-knife” position for safe clearance of vehicles 
  • Easy to operate and maneuver 
  • Features a low profile design with a long reach, making it ideal for railcar unloading
  • Easily connects under trucks
  • Eliminate the need for hoses


A-Frame Loader

Another great bottom-loading arm option from Northern Platforms is the OPW A-Frame Loader. This loading arm is a popular option for LPG loading applications. Its unique configuration enables flexibility and a long reach while remaining convenient and easy to use. Typically used for tanker truck bottom-loading applications, the A-Frame Loader can also be utilized in top-loading/ unloading operations, making it a versatile option. And just like the Unsupported Boom loader, this bottom loading arm also adjusts for changes in tilt or elevation during loading operations. 


Next are some additional benefits and features of the OPW A-Frame Loader available at Northern Platforms:

  • Available in 2″ to 4″ sizes
  • Available in carbon steel, stainless steel and aluminum
  • LPG options feature an all-welded construction
  • Crossovers can easily be achieved
  • For multiple product applications, this loading arm can be mounted closely to others

  • Fully customizable
  • Eliminates the need for hoses


CWH-Series Counterweighted Hose Loader

The last bottom loading arm we’d like to highlight is the OPW CWH-Series Counterweighted Hose Loader. This loading arm’s simple yet rugged construction provides efficient handling and coupling to tank adaptors. At the same time, the flange-by-flange base swivel joints ensure reliable performance and easy maintenance. The counterbalance adjustment is also smooth and straightforward, making the loading or unloading process quick and efficient. 


Below are some other features and benefits of the CWH-Series Counterweighted Hose Loader:

  • Features 4″ arms with a 114″ reach
  • Manufactured from carbon steel and aluminum
  • Includes a Dual Split Flange (DSF) inlet swivel for durability
  • Includes low-temperature fluorocarbon seals
  • The multiple-compartment loading capabilities save time
  • Crossover capabilities easily meet API envelope requirements
  • Comes with braided stainless steel or Rackmaster composite hose


Insulation for Molten Sulfur Loading

If your facility is specifically loading or unloading molten sulfur, then a bottom loading arm alone is not enough to ensure safe and efficient operation. At Northern Platforms, along with our inventory of bottom loading arms, we also offer a variety of loading arm accessories, such as the OPW Custom Insulation Packages. These removable and reusable insulation packages provide superior heat retention, safety, and an uncompromised range of motion, making them an excellent choice for temperature-sensitive loading applications. Available in 2″, 3″, 4″, and 6″ sizes and carbon steel or stainless construction, the OPW Custom Insulation Packages from Northern Platforms will ensure that your molten sulfur loading operations are safe and temperature protected.
