For Christmas I want a new crane.

The guy jumping around at the lower left owns the machine.

The bad thing is the tree wound up in the cab of the truck as well.
What I don't understand is why didn't they position the crane to the side of the trailer then they would not have had to boom out so far

They were thinking, "It's just a Christmas tree. How heavy could it be?"

Or maybe, as in most situations like this, they just were not thinking at all.

One of my irregular tasks is writing legally required (in the UK) LOLER lifting plans, it's not uncommon to find riggers and crane operators relying on 'generic' documents years old, when your moving multi-million £/$ value 'tools' with off-set CoG's etc that weigh tonnes in relatively confined spaces you can't afford to get it wrong, machines can be replaced, people however...

We built a pair large platform freight elevators which had to be installed in the allay way between 2 buildings the platform were 12.5 meters by 3.5 meters in size with dock levelers built in on both ends. Every hanyak and his brother seemed to have mobile cranes in Kuwait and some had very little knowledge of the limitations of their equipment. This one company we liked to use had several cranes and even had a rigging engineer as such although his experience in my opinion but that is beside the point. He came out to assess the pick then said well I believe we can do this with our 25 ton it has enough height and reach and it should be big enough to do the job.
Do you have a 35 I asked him.
No our next sized crane is our big 50 ton.
Ok then I want the 50 for this pick because we have to fly over and lower between 2 existing buildings and these platforms could be considerably heavier than I have them estimated due to the difference in stated weights of materials and actual weights.
But the 50 ton will cost you twice as much.
Yeah and how much would it cost to rebuild a couple of buildings? Not to mention the cost of materials in them or the possible human lives that could be injured or lost.
As it turned out the computer on the fifty ton showing the weight and load limits while making the pick was significant enough that had we used the 25 it might have been able to do the pick but there would have been ZERO margin of safety

I wonder if the operator was watching "How to lift with a crane" videos when he was picking it up.

The main thing's to consider before any lift is capacity of any crane,and weight of lift, and proper footing of the outriggers, positioning of the crane to the object, the placement of said object. It looked as though the crane was of large enough size but was set up in a soft wet field as the right side outrigger sank into the ground! I didn't see any cribbing under the outrigger foot, if there was, there wasn't enough!
