I hate making 2 crane lifts. The last one I did, I tailed for the bigger crane the company has. The lift was only 27000 pounds and I was in a Grove RT650E. The other guy was in a Terex over the road crane of about the same size. We were standing up a temporary silo that either crane could handle alone, but it took 2 to get it vertical. We almost had it vertical and most of the load was on him, when for some reason he boomed up. I don't know what he was thinking. I had out 70 feet of stick and was at about a 50 degree boom angle. All was good. He starts booming up and puts most of the load back on me. I was 3 lights in the yellow before the riggers got him to stop. It was a classic example of one guy was signaling him and another guy signaling me. There was an epic ass chewing and the job was completed without incident.

Lol, that's what I was thinking, probably the size crane they needed to begin with.

The Rigger calls the lift, they have a better eye on what's going on and will give the operator(s) commands.

Not just for safety, but for them to have a better prospective on what they're doing, than being isolated in the cab at tough to see angles.

Tower cranes have them, and some hydros.  The only time they're really handy is when you're out of line of sight, and signals are being called by radio.  I've never run a tower crane, and I've never used a remote, but I've been the signalman plenty of times.  

In my experience, it's a lot easier to run the machine from the seat.  You do a lot of things by feel, catching your swing and whatnot, and you can't feel it if you're not on the machine.

Rotating the beam from the side of the hole to the center where it ws being placed.  Someone forgot to tell Newton what they were doing, and Newton got pissed...

Yep quite a calculating bitch.


Crane company rented our parking lot a couple years ago for some kind of operator training or test.

Moving a 55 gallon drum on the hook just off the ground through a course of cones with tennis balls on em... looked quite challenging

Of course, being Venezuela, they'll probably use a bigger crane and try to pick it up all at once and have that one fall in.

Your avatar is nothing less than perfect for this thread.  Is that the guy in the 60 ton crane?
