My grab is quick release, so we can take it of and fit the hook for careful lifts and put on the grab for unloading and fast loading of laying timber.

How do you find the grapple on the hiab for lifting timber - in comparison to a hook and chains/sling that is? We have a hook on ours with the reasoning of critical lifting as opposed to rapid handling of volume

Its generally used for lifting timber off the ground so works well with the grab, we have slings that we can fit to it if needed.

sectioning with the grab isn't ideal, the operator needs to be on the ball and the climber needs to know how to read the grab. The grab has a large side and a smaller side, the smaller fits inside the larger so it can close tight. When pinching the top to be lifted off, the tension will run from the smaller grab side to the larger grab side, so it is actually lifting from that side, so it is best to start there and work toward. Keep an eye on the rotator and top shackle(type thing) that holds the grab to the crane, this will tell you if it is lifting straight or not, sometimes you are best to extend out to actually lift the top chunk off. Quick hitch is the best way like huck has set up. :thumbup1:

Can you take a picture of your set up for me to look at please mate?

We are looking at a clamshell for moving soil, can this be quick release too?

Felling 5 Ash trees plus an Oak to lift and rebalance. 2 of the trees have been felled and the weight has been taken off the back of the remaining 3 using the MEWP. Back tomorrow to drop the other 3 into the field. Nice job, all chip and timber to stay on site (Some lovely firewood!) :001_smile:
