I understand the frustration in seat switches. I also appreciate Tones concern for inadvertently tripping an external E-stop. In that situation, I don't know what a funa spotter is, or how that operation takes place. I guess I would try to operate so that no men were in uatms way. I also realize this is not always practical nor efficient.
I don't wanna come off as some safety nazi, but I do appreciate the safeguards engineered into the machine's. The manufacturers aren't happy about compromising their good name and reliability for some switches and devices that should have weeded out the Darwin award candidates long ago. But you have to keep in the back of your mind, every rule, device, lockout etc was thought up because someone was killed or seriously injured. Seat switches, for example. If an operator gets out of his machine and accidentally bumps a control on the way off/down or out, that person could be hurt badly. Dozens and rollers. When you throttled up and push or pull the travel lever, you're going without a continual input from you. So know you're in harms way and anyone else in its path. How you gonna mount a moving dozer to stop it? Or a roller for that matter? I'm not saying it's the only way, but I think it's easier to live with it than without. I never want to make 'that' phone call or get hauled into a courtroom for willfull negligence or worse involuntary manslaughter. Just a bit to think about.
