A long-reach, counterbalanced top loader that gives operators a wide, forgiving working envelope for trucks and railcars with variable hatch positions. The Bullhorn geometry delivers smooth, low-torque movement for fast, repeatable drops and safer handling at the rack. Configurable with vapor management, thermal packages, and safety hardware to match your media and site conditions.

Wide working envelope to reach offset or multi-compartment hatches without re-spotting.
Balanced, low-effort control for precise positioning and quicker turnarounds.
Seal-friendly swivel design aimed at long life and lower maintenance.
Built-to-fit geometry (reach, drop, rotation stops) for tight racks and mixed vehicles.
Vapor-recovery ready with hatch equipment or dedicated return arm options.

Refined fuels top-loading with tapered drops and vapor containment.
Chemical service in stainless builds with compatible elastomers.
Asphalt/heavy products with insulation and heat-trace for cold climates.
Racks serving mixed fleets where hatch locations and heights vary.

Sizes & materials: 2", 3", 4", 6" in carbon steel (painted) or 304/316 stainless.
Seals: FKM(Viton), NBR, PTFE-based (others on request).
Counterbalance: Adjustable spring-assist; gas-assist available.
End-of-arm : Threaded outlet; drop hose, isolation valves, dry breaks.
Safety & handling: Mechanical locking bar/parking, travel stops, grounding/bonding clamp/monitor, drip tray.
Instrumentation: Sample ports, gauges, purge points, and valve packages on request.

We set the horizontal reach, vertical travel, and rotation limits to your rack height, island spacing, and vehicle variation so operators can land the drop quickly and consistently—reducing alignment time and strain.

Service: Truck or rail, top-load • Typical reach: 8–15 ft (custom on request)
Pressure/temperature: Built to application; materials and seals selected per media
Connections: ANSI flanged standard; threaded by request
Options: Grounding, position locks

Bullhorn style top loading arms are designed for loading and unloading product into rail-cars. They are excellent for variable reach applications and can aid in maximizing reach and weight capabilities. The TLBS-375BH supported boom bullhorn arm offers 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. Two additional swivels with a tee are 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.
