Komet Trailer - Failsafe in case strut(s) fail
Has anyone developed a brace or clamp that would support the clamshell if the structs failed or perhaps worse, if one failed? I'm quite nervous, considering the weight of the clamshell and the damage that could be done while the sailplane is in the cradle. I liked the simplicity of the Eberle trailer when I had my Libelle.
Thank, Rick |

I am more concerned about my neck whenever I stick it inside the trailer. Looks like the perfect guillotine to me. Did anyone heard of a sudden total failure of the struts?

Thank, Rick I once had a sudden strut failure on my trailer when I opened it. There was a hiss from one of the struts, and I needed my buddy to open it completely (and hold it open). I guess that if it fails in the open position, the top would come down quite fast. On my trailer, I can close the top while the glider sits in its craddle; the ramp is just long enough. The guy next to my trailer doesn't trust his struts (he just bought a used trailer) and blocks the top with two wooden rods (maybe 2.5 m long) against the ground. Bert Ventus cM TW |

Komet Trailer - Failsafe in case strut(s) fail
I recently had a strut "blowout" on a Cobra for an AS-H25. Fortunately, it was just after closing the trailer. Sounded like I had just stuck a knife into a tire.
The general failure mode, however, is gradual loss of pressure. They get to where they don't help lift and won't keep the top open. If one does fail catastrophically, you should have time to react and get yourself out of the way. But your plane, if anything is in the path, may not fair so well. And if you are looking for a brace to handle the catastrophic, it needs to be hella stout, as they will likely get several hundred pounds of force on them, and not necessarily a straight down load, if one goes a bit before the other.

Thank, Rick If you are really concerned about that, carry a broomstick that is cut to the correct length to fit between the U-channel top and the bottom of the inside. Wedge it in first thing after opening the trailer. Doing it on one side is enough, the top will twist if the other spring gives out but it will not collapse. Herb |

Komet Trailer - Failsafe in case strut(s) fail
Most newer Cobra trailers have a little-known feature that can hold the top open if the gas struts have gotten weak or if there is a load of snow or ice weighing down the top. The square steel tube that houses the gas strut often has a small (1/8 to 3/16) diameter hole near the junction of the inner and outer tubes. A pin placed through this hole will prevent the two tubes from telescoping and adds a measure of security if the top has a tendency to sag.

Komet Trailer - Failsafe in case strut(s) fail
We recently replaced the struts on our clamshell trailer as they
were getting rather soft and we were starting to rely on the broomstick solution. My syndicate partner sourced replacement struts which came with a standard option of a spring loaded fitting which popped when the strut was fully extended, locking it solid by preventing the telescopic action. The lock is easily reset to close the lid. It seems to be a common option on gas struts and, being self contained, needs no mods or extra pins. Well worth the small extra cost over the standard strut.
