Think your safer being able to jump off the pallet if the machine is in gear advancing and your bit of string off to the lever breaks or something meself.
Somewhere I have a pic of the Chief of the Canadian Defense Staff testing out my fresh built materials hoist, by running it up to its 6mtr limit with him standing on the little load platform. Confidence? Gotta hand it to these military chaps.
Worse thing I can think of personally is when I left my jcb idling in gear with the handbrake proper off but the front bucket resting on the yard as a sort of lazy mans handbrake to open the exit gates (fluid shuttle/torque converter) and I had put the pump return to the tank on the wrong (blank) fitting after doing some work on it that day. It started fine and all seemed well, but while I was fiddling with the gate catch the lack of return to tank began to dump too much fuel into the engine and it revved up and proceeded to charge me down with the bucket scraping a big divot out the drive. I managed to fling the gates open, side step it and get aboard and kill the engine before it crossed the road and demolished the neighbor's car and house. Funnily enough, ever since I've been really careful about selecting neutral before getting out the cab. There's something about being chased down by 7 ton of your own machine that makes you more careful in future...
