Experience of clamshell buckets?
Posted: Fri Oct 19, 2007 10:46 pm
I´m shure that Nick can tell from the subject that it´s me asking.
I was looking at a job yesterday. It was a drainage of a house (basement). The usual method is as you all know to stand along the wall and dig along the wall.
But one part of one of the walls are "countersunk" (don´t know how to describe it in English) about 2-2,5 meters compared to the rest of the wall. The length of this countersunk part is about 4 meters, to small for my excavator so I can´t stand along this part of the wall with my excavator. There´s also a roof over this part to make it even more complicated.
And no, I don´t have any photos. But I have made a drawing. The black rectangel is the roof and the red line is the "complicated" wall.
I have done a similar job once. I dug that from the side of the wall instead of along it. But that means digging a much wider trench, more soil that should be stored on the site during the job, more backfilling etc. That method works but it isn´t a good method.
So my idea is to use a clamsell bucket with a rotator. That way I could dig a narrow trench and still be standing on the side of the wall.
Has anybody of you used a clamshell bucket? Is it the right method?
Any other ideas?
I guess that a clamshell bucket means less m3 per hour where a normal bucket could be used?
But in this case a normal bucket isn´t performing at its best.
