Our standard configuration bottom loading and unloading arm with 5 swivels has been a dependable, safe and clean method for tanker fill/discharge for many years.
Experience has shown that if the tanker connection arm ("B"-length) is fitted with high weight components such as a ball valve or breakaway coupling, the arm can be difficult to maneuver and handle. To prevent this and ensure that tanker loading is a one-man operation, we have designed a six swivel arm as shown.
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 which 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.
