Hydraulic Release Technology
Onboard Systems has pioneered and developed hydraulic release technology for helicopter external load work. A US Department of Interior Aviation Management Technical Bulletin dated July 16, 2004 discussed common safety issues linked to inadvertent cargo hook releases. The findings show that large amounts of movement during external load operations can cause the cargo hook release mechanism to be accidentally activated by tension on the release cable due to improper rigging.
Our TALON LC Hydraulic Cargo Hook uses a hydraulically activated release mechanism that takes the place of a standard manual release cable. This new release system requires no rigging and is conveniently routed with the electrical release cable. Best of all, snagging or damage to the hydraulic cable will not cause the hook to open.
