Tear-off Safeguard for Transverse Forces (non-axial)*
This emergency break device enables hose disconnection in case inadvertent non-axial hose pull forces are encountered. Pull forces, for example, may arise when road or rail tankers are loaded and the vehicle starts moving without the hose being disconnected after the loading operation has been completed. Coupling socket (female portion) and coupling plug (male portion) are interlocked during loading. The plug is permanently mounted on the vehicle. Normally, the connection is separated by moving the slide collar back. If rope pull forces are exerted the disengaging disk acts against the collar thus moving it back.
- Shear or tear-off pins need not be replaced after an emergency break, simply plugging the parts together restores the connection.
- The coupling offers break-away and quick-disconnect functions in a single system.
- To function properly, the coupling needs not be arranged in the middle of the hose but is located on the vehicle itself: The vehicle when leaving will thus not carry along a disconnected hose section; instead the entire hose remains at the loading station!
*Note: The above described two features may also be combined!
