Cat 301.8 Earth Moved Per Hr?

heavyoperator

With a 16" bucket how much earth "regular dirt" can a 301.8 move per hr. I have to give a qoute this info would help me.While I'm at it, how much concrete should be able to be chipped per hour ranging from 4" to 2 1/2 feet.

what capacity is the bucket? how many times can you cycle a minute? don't forget to include non productive time such as set up, phone calls, etc....realistically, i figure i have 50 productive mins. out of every hr.

by the way....you don't "chip" concrete with an excavator...unless you have a hammer.

and if you do have a hammer what size? this is a small machine you arent going to have much luck breaking 2-1/2' of concrete unless it is green. I would have tou say your bucket capacity is about a cubic foot, times average cycle time for a fair operator is 30sec. so figure 2 cubic foot a minute average because there will be times when you are more productive and times where you will be less taking day's 50 minutes of actual digging per hour; id say about 100 cubic feet an hour say 3 cubic yards give or take and with the concrete is there rebar? wiremesh? reinforced with fibers? that is really a tough one to figure how much you will chip in an hour. also keep in mind that this machin only has a dump height a little shy of 7' so if you are loading a full size dump truck no dice. if you are just piling the dirt up along side a hole you will recive optimum productivity. Also are you trenching or shaping if trenching you have to account for repositioning. As you can see alot goes into this i recommend getting a few books on estimating excavating they will serve as an invaluable guide in your endeavors. I cant really say from personal experience here because I have never run a machine this small.

Heavy,

We have owned a Bobcat X320 with a 16" bucket for 10 years. It is basically the same machine. It is the best pick and shovel I have ever owned. As to what it can do that is very project specific. Given a specific job description I might be able to give you a pretty close estimate of what "we" could do.

We also have a Tramac hammer for it and I hope to never pick up any of our 90 LB breakers again. "what can it do", What are the conditions?

The only reasons to use these machines is a restriction on size or you have no other machine. So if you want to give a good descrition of the work and we'll try and get you a god estimation

I almost always have concrete saw cut into sections before I demo it-(2.5ft is some pretty major stuff for that machine without a breaker and I personally shy away from running a breaker on compact equipment-even though they make em for the machine doesn't necessarily mean they are good for it-just my 2cents.) It usually costs $150 on the average to cut and I figure the time and wear and tear it saves is well worth it. As far as cycle times, it all depends on what type of soil....hard, sticky, rocky, etc. I'm willing to bet that most guys on here are much faster than 30secs on average even with a full rotation. In loose soil, the turntable barely stops on my little 435, but get into the tough stuff and it's a whole different story. If you know your area, then you know your different soils and go from there. I typically figure the time it takes me to load a truck and use that as my basis of estimation. Good luck!!
