Loading Arm Accessories Parallel Device For Bottom Loading Arms E2588

Parallel Device for Bottom Loading Arms

The arm is fitted with six swivels for complete 3-axis movement of the tanker connection, allowing for tanker height changes during filling/discharge. The arm is additionally fitted with a parallel bar that holds the tanker connection arm ("B"-length) in a horizontal position irrespective of the primary arm ("A"-length) position. This makes tanker connection and disconnection much easier. The B-length also has a gas spring fitted allowing the operator to raise and lower the B-length with total ease.
