Truck Loading Arms

Bottom Loading Arms

Bottom loading/unloading arms are designed to be connected on the side or on the rear of the tanker and sometimes for both.

Bottom loading arms are provided with 5x or 6x swivel joints and 1x balancing system (spring cylinder). In order to keep the connection pipe horizontal, bottom loading arms (type BLA124. BLA125, BLA144, et BLA145) are provided with a pantograph. They can equipped with a large number of accessories.

Depending on the requirements involved, the design can vary from standard solution to tailor made.
