Where I am, in British Columbia, the solution formoving even the biggest windows in single family homes is to use ten men and a boy.

It is exceptionally rare for a contractor to have equipment to move literally anything that takes less than four laborers to move by hand.

Not here in the Netherlands. By law anything heavier than 23kg should be carried by a machine. In principle one can carry something heavier, but then there needs to be a written plan etc.

It's very common to carry stuff with a small crane. If it needs to be carried to thd back of the house which is not accessible, they set up a bigger crane.

I bet y'all have comprehensive workers compensation coverage and good healthcare too. Half the contractors around here lie about carrying a personal injury policy and several I've worked for had a standing policy where if you fell off a roof, scaffold, or ladder it was understood that you were fired before you hit the ground.
