JB, I just remember article I read long time ago about changing the bulb on top of Empire State. Now holding onto a needle in that height makes me feel slightly dizzy in my chair
Here is at least a picture of it.
Nice pic Prokop, That guy has to have some nerve! sad you can see WTC in the background.
If I used those lifts as much as you, I'd want to know the details of how the lock valves were installed on the cylinders and what to do in any emergency for any brand of lift.
Jim, No I don't know them mechanically that well, we do give them a good looking over to try and spot obvious defects though. the biggest threat is whats under the tires, like soft ground, collapse pipes under paved areas etc. any kind of sudden drop in one of the wheels and your gonna be in trouble. Guy at the rental company told me 2 guys in New York got killed when a big one went over, they were washing windows and were driving the wheels to reposition when they drove down a ramp in the walk or street, didn't realize it from up there til it was to late.
We've had quirky machines were we had problems with restarting when way up, had to call service department so they could trouble shoot over the phone, they have contingency plans where there are things you can do inside the control panel in the basket, where parts and wires can be swapped around for help getting the machine back to the ground.
Basically if you do get marooned off road 100 feet in the air, 911 ain't gonna be able to help you, fire dept is not going to be able to rescue you. At that time a factory trained technician is going to be your best hope.
We always keep a long 3/4 inch nylon safety rated rope with us up there along with a couple of carabiners and a little bit of experience in repelling, in the event we had to rescue ourselves as a last resort in an emergency.
