TLBS-374 Supported Boom Top Loading Arm

Supported boom top loading arms (TLBS-374) are designed for loading and unloading product into tank trucks and rail-cars. They are excellent for variable reach applications and can aid in maximizing reach and weight capabilities. The supported boom top loading arms (TLBS-374) offer an additional pipe section and swivel to provide extreme flexibility at the loading position. A single swivel (with pillow block support) at the inlet and a spring balanced double swivel at the base allow for up/down and left/right movement. These components achieve a longer reach requirement while minimizing the spring balanced section of arm. An additional swivel at the end of the arm allows the drop tube to stay vertical. Available in Right Hand or Left Hand, Up Feed or Down Feed and Horizontal Feed Loading configurations.

Extended Reach Supported Boom Loading Arm for Truck and Railcar Loading

The TLBS-374 Supported Boom Top Loading Arm from Excel Loading Systems is designed for applications requiring extended reach, increased structural support, and enhanced stability during loading operations. This model is ideal for tank truck loading, railcar loading, and industrial fluid transfer systems where longer reach and controlled movement are critical.

Unlike unsupported boom designs, the supported boom configuration provides additional structural reinforcement, reducing stress on the spring assembly and improving long-term durability in demanding environments.

The TLBS-374 is commonly selected for high-cycle loading racks, multi-compartment loading, and applications with variable truck positioning, where both reach and stability are required. 

• Supported Boom Design
  Provides additional structural support for extended reach applications, reducing stress on key components and improving longevity.
• Extended Reach Capability
  Additional pipe section and swivel configuration allow for increased reach compared to standard loading arms.
• Enhanced Stability During Operation
  Supported boom design improves control and reduces deflection during loading operations.
• Multiple Swivel Joints
  Ensures smooth articulation and precise positioning for efficient connection to tank trucks and railcars.
• Spring Balanced Operation
  Engineered for ease of use, minimizing operator fatigue while maintaining consistent positioning.
• Vertical Drop Tube Control
  End swivel ensures proper vertical alignment for safe and efficient product transfer.
• Multiple Configurations Available
  • Right Hand or Left Hand
  • Up Feed or Down Feed
  • Horizontal Feed Options

The TLBS-374 supported boom loading arm can be configured with:

• Loading valves
• Cone deflectors
• Drop hoses
• Vapor recovery systems
• Grounding and bonding systems
• Vacuum breakers
• Steam jacketing
• Pneumatic or hydraulic balancing
• API couplers and dry disconnect systems

Each TLBS-374 loading arm is engineered to match your specific application, including:

• Working reach
• Drop length
• Rotation stops
• Rack height and clearances
• Vehicle positioning variations

This customization improves operator ergonomics, loading efficiency, and overall system performance.

Each loading arm includes full Installation, Operation, and Maintenance (IOM) documentation.

Routine maintenance typically includes:

• Swivel inspection and lubrication (if applicable)
• Seal condition checks
• Counterbalance adjustments
• Visual inspection of hardware and components

Excel Loading Systems stocks seal kits, replacement components, and wear items to support ongoing maintenance and minimize downtime.
