Firstly i want to start off by saying the danger with using cranes in tree work is underrated. It seems climbers are pretty casual with cranes but its crucial to keep your wits about you.
With those photos, as Ekka pointed out its evident the cuts made were not judged correctly and there was only one rope point. Something positive was the climbers position was good.
The cut that Ekka has highlighted is a mistake that shouldn't be made. Ways of avoiding this is;
Good communication between the climber and an EXPERIANCED dogman to tell the climber whats going on is very important.
Using correct crane cuts, as a climber working with cranes you should know where your bar tip is and know whats required for each cut.
Having a second roping point while cutting is standard practice and shouldn't need to be elaborated on, how long does it seriously take to put your lanyard on...
A few extra points i would like to point out while I'm on the crane topic;
Don't be afraid to use cradle systems when taking horizontal branches, there is no need to "stand up limbs" with every cut!
To take the pressure of you as a climber have a couple of extra slings so after the crane has removed the last piece of wood out safely you are able to set up the next lift before the hook arrives.
Having a bigger bar is not always the best solution, i always would recommend using a rear handled saw with plenty of power. You have more control of the saw and cuts are made smoothly, quickly with less effort than the likes of a top handle saw with no chance of missing wood that needed to be cut.
DONT tie into the hook while its under load!
The last and most important thing i want to say now is also the hardest thing to do. Know whats going to happen BEFORE it happens. Know where and what that piece is going to do so you are well out of harms way. It sounds silly but i always think about whats going to happen if.... and have contingency plans worked out so in case of a worst case scenario you able to deal with it safely, its kind of like risk management but a constant updated one.
