I have a potential buyer for my HD5G Loader .. I cant find a spec. on how much
it will lift .. He wants to load rocks with it .. I has two large weights on the back of the
machine .. Any Idea in LBS what it can lift .. Thanks Mark

| Norm Swinford book lists it at 1 cu yard and 16,200 lb shipping weight. All the specs are not listed for the HD5G but a 1 yd machine should be good to 5000 lb lift, quite a bit more to tip, someone may have a manual out there. If it is AC, this is the right place to get your answer. |

i am sure it will load rocks. i do not have an exact spec for it but i think it is a 1 1/2 yard bucket. it will load rocks or dirt no problem ------------- HD5B, HD5G, (2) FARMALL A's, CUB. DO IT RIGHT THE FIRST TIME, IGNORE THE LAUGHTER. FLANNEL IS ALWAYS IN STYLE. |

| Well, hydraulic pressure is only about 1000-1200 psi, so with 2, 5.5 (I think, maybe 6) inch cylinders that would be about 47 square in (or 56 for a 6 inch cylinder) times 1000 psi, which is about 47,000 pounds. However, the mechanical linkage is such that I'd guess that your lifting capacity is about 40% of that, so, it seems to come out to about 9-10 tons. Does that seem right to everybody? Looking at the pic, I might be a little high on my 40% guesstimate, maybe more like 25%, so maybe 5-6 tons |

| It may be able to pressure in at greater than 5 ton but a 1 yard bucket heaped to a yard and a half of clean white rock is only at 2 ton, white rock 1" minus or tailings is a little more and may go 3 ton but you can't fit 10 ponds in a five pound sack no matter how hard the wife tries!! |

| I've lifted 3000# with mine using a chain over the cutting edge of the bucket, the crawler will tip and balance on the front truck roller and the idler, but not try to rock any farther with the weight. The crawler only has 1 counter weight on the rear. Previous owner claims that he used it to move a full 1000 gal. lp tank, but I think he had the chains hooked on the rear of the bucket going straight down to give the cylinders more mechanical advantage. |

| I would bet it can't lift more than half its weight at the bucket center when arms are at max reach (forward). That would be close to the 8000 lb if the operating weight is close to 16000 lb. It should be tip limited, not hydraulic limited. |

| I went back to Norm Swinford book, he does list some spec for the larger HD6G to get you in the ballpark. It is 21000 lb ship wt, 12300 lb tipping load, 7900 lb lift capacity, 1.5 yd bucket. I am thinking someone out there may have a spec book. CAT published a lot of specification books to use for estimating jobs, maybe Allis did that as well. |

Standard bucket is 1 yard, I loaded with it and heaping the bucket with black dirt would be 1 1/2 yards , will lift it to full reach with no problems , weight at about 3000 lb. Loading stumps and such with large dirtball, a 6 ft stump seemed to overcome center of tip point first but the machine would still lift it.
I have picked up items to a height of 4 ft weighing over 6,000 lb. At the lower stroke or below the center line of the track top I have pried out cement footings and such using leverage of machine drive and hyd lift of over 15,000 lb.
The loader arm lift will pich up enough weight that the curl cylinders will not rotate bucket back level.
Then also the pressure of the pump if the wear plates in the gear pump are worn will be less. I know i use to be able to kill engine with hyd pump if cylinders were full stroked , and the relief valve did not open soon enough. I have the HYDRECO pump on mine, early units used a Vickers pump. Pump capacity is 32 GPM at 1800 RPM
Scrapped a few cars (full size 70's) where I picked them up from side, with chain back to bucket through roof so width of car was in front of bucket and loaded onto trailer. If i picked them up length wise with front or rear in bucket the counterbalance made the machine a little tippy. ------------- Faith isn't a jump in the dark. It is a walk in the light.

| I have and HD6G without a rear weight. I've had solid rocks as big as the bucket in the bucket... I was riding on the front truck though... I've always been able to lift anything I could get into the bucket. I vaguely remember looking the load up and recall 7000 lbs as the limit... |
