Up way too early with my youngest so we started youtubing to keep her quiet why everyone else slept. Stumbled onto this neat video.

Quick question for those in the know: Did they leave the extra rear counterweights off for clearance with the canal berm, or could they have raised them up higher to clear the berm while doing the initial pick? I can see it wasn't necessary to have them on for the entire pick, but I was wondering if that was standard practice to take them on/off during a pick like this?

Not really sure but guessing that they only needed them on for when they needed to boom down. Maybe if they were on too soon they would have made the weight too much on the back to be able to swing?

Maybe Crane operator will see this and give a better explanation, I know what I'm thinking but putting it into words just doesn't come out right!

Something along the line of keeping things in balance not too much counter weight and not too much load on boom end. Add a little at each side and no real stress in either area.

I think those not trained in this field would hardly be allowed to build. I know that before using cranes and other lifts, they are tested. For example, the company Loler Testing In Kent provides services for the design of the necessary capacities of receivers for various production and construction needs. And if you consider that such things are strictly controlled, I think they have received permission to use this particular equipment in this particular activity.
