Parking Position Lock sketch




Parking Position Lock:

A positive locking system that prevents undesirable and random movements of the loading arms. Also referred as a Base Swivel Joint Locking System.

Filling Position Locking System Sketch

Filling Position Locking System:

For avoid back pressure flashing incidents while top loading, available a simple positive locking system for top loading arms that prevents potential flashing incidence that could cause personal injury, equipment damage and subsequent product loss.

6. Safety Break-Away Couplings for Aviation, Oil, and Gas Loading/ Unloading Applications

Safety Break-Away Coupling

Size: 2" x 300 lbs.

Investigation of drive-away incidents involving LP Gas Loading/ Unloading arm assemblies has led AE to develop protective break-away couplings that, if separated, quickly form an air-tight pressure seal that prevents LP gas from loading arms or tank trucks from escaping through the separated coupling half and spilling to the ground. Subsequent R&D efforts have resulted in the manufacture of `ASSEN' Safety Break-Away Couplings (SBAC) utilizing shear-pins that are:

Available in 50mm (2") to 85mm (4"), and larger sizes
ANSI Class 300 and Class 150 
Available in Stainless Steel, Carbon Steel and Aluminum
Available with seals of Buna-N, Viton®, and Teflon®
Flange-ends, Threaded-ends and combinations
Simply constructed for ease of reassembly after separation without special tools
