Do all unrestrained vehicle door coil springs require a safety cable, or only certain types?
I didn't get a picture of this entire spring arrangement: off to the right, the end of each spring is attached to one end of a short length of cable. The cable runs through the sheave of a pulley, which has a second cable attached to the pulley's strap, this second cable makes the connection to the door.
It's hard for me to imagine how a safety cable could be inserted through the springs without interfering with their operation, OTOH things could certainly get nasty if a spring or its connection point failed.
I did not note the identity of the door operator's manufacture so I can go back to their instructions,.
Is anyone familiar with the safety cable requirements for this arrangement?
Thanks.
