Title: Making Digging Safer
Post by: The Old Ruminator on December 04, 2018, 08:35:35 pm
We have been working on this for a while. It works like a car air bag. In this case there is a trembler device which activates the inflation cylinder and saves you from injury in a collapse. Mr O' Doc manfully agreed to test it out whilst I collapsed the choke. Luckily it all worked well and he escaped injury. We need more volunteers for testing as Mr O'Doc said now way was he doing that again.

As the boulder moves it could trigger a fuse and blow it up into small harmless pieces

Yes clearly at the experimental stage hence the need for more volunteers to move this exciting development forward. ;)

I'm glad to read that you've managed to incorporate an inflation cylinder into the device, OR.

At first I thought the caver at risk had to inflate the airbag himself by mouth when the trembler alerted him to the possibility of an imminent collapse.



(And yes - I've used the masculine pronoun throughout, but I'm not being sexist.  I'm just sure that no lass would be daft enough to try that thing out!)

I like this idea, instead of an air bag thought, you could have a doodah that fills the chamber with rapidly setting expanding foam. Obviously the digger would need to keep a snorkel at all times.
