just bought an excavator. I have a few bucket questions

I just bought a Doosan excavator that was advertised as having a 30" bucket. Is that a bucket width measurement? How can I calculate the maximum heaped capacity of this bucket? Why are most excavators' buckets classified by inches rather than capacity?

I would like to get as close to a three yard scoop as possible on this machine. The dirt I will be digging is very soft river silt and has previously been disturbed in the recent years. Is three yards asking too much from this machine in this case? What inch bucket would I need to get close to this? 48"?



Here's a pic of the machine and bucket. It has a quick change setup. Will I need to look for a special type of mounting setup or are excavator buckets somewhat interchangeable?

Thanks in advance for any input. Excavators are pretty new to me. :usa

there is probably a metal tag on the bucket that states yardage
as for the width ... usually the bucket width matches the pipe your installing
digging with a trench box you need a bucket to match the box
if you want it to hold more add sidecutters

Well a yard is 27 cubic feet so 3 would be 81. In simple math 4 feet by 4 feet by 4 feet would be 64 cubic feet. 5 feet cube would be 125 cubic feet.

You need to know what kind of mount you have and buy bucket for it.

Thats definetly a small bucket, no doubt great if you want to bury 18" pipe but not much use for throwing muck about :D

Yes generally an excavator bucket is measured by width not capacity.

You will probably get up to about 54" as a digging bucket with teeth quite easily, I would expect bigger to be available but not so common. Thats where a welder and some plate comes in handy.
How big you can go will depend on the weight/density/wetness of the material and the thing in the cab holding the levers.

If you've got an operator in the cab you will almost certainly get away with a bigger bucket ( more production ) than you will with a greenhorn.

I managed to find a couple of adds that have bigger buckets.

As for compatability you need to get the existing bucket off that hitch and see what the mounting is. It could be a pin grabber in which case you need to measure the pin dia, centre to centre, and width between the webs
(dipper width) then go hunting a bigger bucket.

If its not a pin grabber, then what is it as that will govern your choices.

This states standard bucket at 1.66cu.yds

We have moved on and now were lost....
Serv if that your digger them it would appear to have a Geith pin grabber type hitch which should make it easier to locate a bucket,just measure the distance between the ears and the distance between the pin centres.This will allow any supplier/ seller to be sure that his product will sell.A machine of that size should handle a 1.5m or 2m digging bucket at her ease.

When it comes to buckets you need to measure the one that fits your machine and get one exactly to fit, (measure twice so that it fits your quick change). I found out the hard way that not all 120/135 size CWS quick change lugging is the same. I bought a rake that would fit Hitachi EX, ZX,
John Deere, Komatsu CWS quick change. I have a Case 135 and I ASSumed it would also fit mine-wrong! I should have measured before I bought it.

Looking at specs for your Doosan 300 machine it showed a maximum bucket capacity of 2.3 yards.

Here is a spec page that shows bucket options for the Solar 300LCV

this has some photos that show the label plus c/yards
it depends on the style/ shape of bucket ... how much it will hold... that is a good size machine so 4 yds. should be to much to handle.

the quik connect the bucket will interchange as long as they are 200 style or 300 style etc... a 200 komatsu won't fit a 300 komatsu, 2 deere to 2 komatsu will... i think.. check with a dealer they will steer you in the right direction..

Rental places will rent buckets... or demo to try ...

government and bacon davis jobs have pay scales rate at bucket cap... that wjy the label.
I've had Corps inspectors look at label .. then ask what the company was paying....

Last Corps job I worked the company didn't know or care maybe, about the difference between building and the outside stuff, which is usually half.. everything paid building scale..... which was great for pay for building parking lots.. The skid steer didn't get many hours on my timecards..... it was horrible either scale..

First of all, you mean Davis Bacon. and secondly.....that has nothing to do with the size of the machines bucket lmao.

and lastley, the bucket tags are not there for the sole purpose of "Bacon Davis" jobs :rolleyes:

Not being a smart*** just dont want serv to get some bad info that's all, also i have my reserves about that machine swinging a 4yd bucket

EDIT: since I ventured a little off-course I might as well finish my ramblings. I have seen Davis Bacon wages clear up to $35+fringe and I bid a job last week that the DB was under minimum wage because it was government "hud" money.....and no where in any pay scales have I seen anything about a bucket capacity wage change. There is a ton of good info on HEF and I am sure there is even some about prevailing wage ;)

Whoops!!! 4 ft. not yds... and a shouldn't..." that is a good size machine so 4 yds. should be to much to handle."

I did look at DB after you mentioned that ,,,, it appears that they have done away with the yds,,, things ... but that was 14 years ago.

Hello, here a response from the Netherlands. About the size of the bucket, we talk about the volume no matter which the width of the bucket is. So i'm working with a Volvo EC 290 CLR in Holland and this machine has 3 buckets to use. The volume is 1000 liters, first one is 2.oo meter wide, the second 1.10 meter and the third one is a heavy rocket for demolition work. So it is very interesting for me how it works about the sizes of the buckets yuo have to use.

The 2 meter holds the same as the 1.1??
How wide is the rock bucket?

Also - 1000 liters = 1.3 yards, so you are saying that your 290 size bucket that is 6.5 feet wide only holds 1.3 cubic yards???????

WOW, thanks for all the info guys. :drinkup



I had expressed my interest in a larger bucket to the seller of this machine and he offered to trade the pictured 30" bucket with a 48" bucket off of a 2002 Daewoo 300 that he uses at his ranch. But when he said he might have to take the quick change setup, I told him I'd just keep the 30" (and quick change setup) and find a larger bucket elsewhere. The 48" bucket was in another city, so I couldn't take a glance at the tag of that one. I didn't even look for a tag on the 30" either. I'll look at it in a week when I get up there to pick her up.


A friend that owns a local scrap yard (he recommended that I buy this brand of machine) has a few buckets in a corner of his yard that came off his Daewoo's. They looked larger than the one on this Doosan. Maybe one of his will work. He doesn't use buckets for his business anyway.


stock,

you are correct on the Geith pin grabber setup. Here are some pics of that.

Some explanation for you all. The 2.oo meter bucket is the ditch bucket. The 1.10 meter bucket is a small bucket to dig trenches. Both has a volume of 1.3 yards. The bucket for demolotion works has a open bottom with spiles and teeth . I have pictures of it, but can't post it. Otherwise go to www.bouwmachinesforum.nl and see the post Volvo EC 290C LR or go to company Biemond en van Pelt and see the pictures.

If you are digging soft silt, you might want to look for a clean up bucket that has a bolt on cutting edge, without teeth. The end result when digging is smoother and cleaner. And why wear out teeth if you don't need them? If you are in rock or very hard soil, you will need teeth. But for many soils, a straight cutting edge works well. These excavators have incredible digging power.

For most digging with my Hitachi 270, I run a heavy duty clean up bucket that is about 62 inches wide. It came off a Cat 325 and has the same mounting set up. Struck capacity on that bucket is about two cubic yards, but when heaped it can hold three yards or more. Your machine is bigger, so it should be able to handle a bucket that size without difficulty.

My 135 has a 54" cleanup bucket. The 200 size machines I see have a 60" cleanup. A 66" CWS bucket advertised for sale said it was for a 300 size machine. Do not know the capacities,

On my 2800Q Linkbelt, weighs 50,000 lbs, long boom and stick, not a long reach, I am running a 1.5 cubic yard bucket, 48" wide with no sidecutters, my 30" bucket is .63 cubic yards to small for the machine, but I cut off the front pin holes added 1 1/2" to spread it out now I can use it with my quick disconnect. The new ratings are heaped not struck, that was back in the old days. I suggest going to the manufactures web site and see what they say, that would be your best bet. danhoe

I took a picture of the regular buckets which I use by the excavator. There are also some special attachments for the machine, we will transported them to the working aera when necessary.
