Variable Reach Top Loading Arm | Top Loading Arms | Model 621-BC/721-BC

About the Variable Reach Top Loading Arm: 

The Variable Reach Top Loading Arm is the perfect solution for efficiently filling road tankers from the top. Its flexible design, with variable reach, allows you to fill multiple compartments of a tanker without needing to reposition the vehicle, saving both time and effort.

  • Model 621-BC is ideal for high-volume or frequent use, while
  • Model 721-BC is suited for lower volume or occasional use.

The loading arm’s design features four swivel joints, allowing precise horizontal and vertical movement for optimal positioning. A compression spring balance cylinder ensures smooth and controlled movement of the arm, while the loading valve offers either a hold-open or stay-open function, depending on your operational needs. For added convenience, the arm includes an extension or remote control option for outboard loading valve operation.

Additionally, a vacuum breaker is integrated for fast and efficient drainage, and the arm is available in both left- and right-hand configurations to suit different loading requirements.

This product is manufactured to meet ATEX/PED standards, ensuring high safety and performance.
