Skidsteer Lift?

[20 20]

From what I can tell to get a close estimate for what a wheeled skid steer can handle{safe load} divide the weight of the machine by 3.95. Example, my case 1840 weighs something like 5558, so I'd divide that by 3.95 = 1407lbs. a 10000lb machine could safely lift 2531lbs. Of course I know for a fact my machine will lift much more, I base my math on what the manufacturers would call a "safe operating weight". Now if a person adds counter weights or if it has tracks etc then of course the weight limit will change.

Maybe my math is wrong but my skid of quickrete was of thirty six 80lb bags 2880lbs, plus skid weight and my forks. Not exactly 3000 lbs but you get my point, it will lift!! As far as pressure, I had Rick Wallace check it with a guage the day I picked it up and it was a hair over 2600 psi right from the factory.

Anyways im guess the S250 will be more machine in many ways than I need so Im going to run one this weekend if I get a chance...

Thanks for all the info from everyone.

That math may work for an old machine but is low for a newer machine.

J J, when I lift anything heavy I have my backhoe on plus my tires are loaded and my seat is also loaded with me ofcourse

Here are the specs for the bobcat ct 440, If your lifting over 3000lbs then you're definatley exceeding its limits.

Lift Capacity at
24" behind Lift Point 1870 lbs, 848 kg

Maximum hydraulic lift capacity at 24 in.
behind lift points (measured at 15 in. above ground)* 2625 lb.

I understand, and all that extra weight makes a difference, and until the relief valve goes off, you can lift. However you might be stressing the front end a bit after lifting those heavy loads for a while. Although you can, doesn't mean you should.

Did you perhaps tweak up the relief valve settings?

I know what the factory specs are for all the machines we have been talking about, I originally asked if anyone has real world experience with their bobcat SS and what they will lift, if that is factory specs then thats what I was the info I am after. I guess what I can take from this conversation is read the specs and thats what ya get...

BTW dont call the Bobcat police on me for exceeding the factory limits on my machine

 

[tinman955]

J J, I understand liftin that kind of weight all the time isnt good for my machine, to be honest thats not what I bought it for. Thats one reason I am looking to buy a SS for fork type use. I would rather be digging with the hoe on my tractor

Thanks again

You are probably correct, like I said it is just an estimate and from what I could see it is still close to some newer machines{if anything under}. I notice there is also a standard set that the operating load is 35% of the tiping load. Example if a machine has a tipping load of 3549lbs then the operating load is 1242lbs Give or take a few lbs.

The 35% thing is for CTL's.

Don't take my post the wrong way, just sharing info, I have exceeded all of my equipment at one time or another. I just figure if your planning on lifting 2000lbs all the time then get a machine that would be rated to lift 3000lbs that way you'd be operating "safe" and within the "machine capabilities". Are there really bobcat police :laughing: what is their number

correct, I quess the best thing to do is go to the stealers or call the manufacturer and find out exactly what a/the machine is capable of. I use the info I gave as an estimate that way if a person were to just go out looking they could get a rough idea of what a machine is capable of. The only 100% way of getting exact info is from the manufacturer. :thumbsup:

The tipping load will vary based on the extra weight on the back, and that is a fact.

 

[IslandTractor]

I don't understand all the confusion. Ratings for skid steers and tractors are different. For skid steers they typically focus on safe lifting with an eye on tipping over. That makes sense as these are short wheelbase machines with little external ballast. If a skidsteer is rated for one ton it probably has the hydraulic capacity and loader strength to lift two tons but ballast is a limiting factor for safe lifting.

For tractors with their longer wheelbase and owner's manuals specifying the need to add rear ballast when you use the FEL, the lift limits are probably more realistic in the sense that a Kioti/Bobcat rated to lift 2700lbs will lift that to full height and that is the max it can lift that high. However, as the OP noted, if you are not lifting to full height you can certainly lift more than the "rated" amount safely so long as you are properly ballasted and are cautious in moving with such a heavy load.

Most of us always want more, but the manufacture are being conservative and using safety in mind. Most people know the hydraulics will have the capability to use max force with the cyl at 90 degrees. The loaders can not ever get to that point, so the lifting force will be less. Probably after testing, they set the figures to lift a load safely. But who ever lifts a load at 20 in behind the lift pins. Why don't they do a real world test as I mentioned in my above post. They are trying to sell tractors based on numbers.

Like someone said, take it home and use it in the situation you have chosen to see if it meets your specs.

Just a side note. I have often wondered why someone would put a chain in a bucket hook and use the front of the bucket to lift, when if common sense is realized, that the backside of the bucket will always lift more.

However, the closer the lift point gets to the cyl mount, the lifting potential goes up. This is fact.

These are almost certainly 3PT specifications. No manufacturer I've ever heard of lists FEL lift capacity at 24" BEHIND lift point whereas that is the standard for 3PT measurements. Standard lift specs for FELs are lift to full height either at 1) pivot pins, 2) mid bucket or 3) 500mm in front of pivot pins

 

[20 20]

IslanderTractor; You are correct I miss wrote the info here is what the FEl can lift, sorry for the mistake

Lift to full height (at pin): 2,600 lbs [1179 kg]

Lift to full height (at 500mm): 2,050 lbs [929 kg]

 

[J_J]

FWIW, 500 mm equals 19.68 in

ROC is figured at the top of the lift pattern so lifting say waist high is still well within the margin of safety.

NO!

The tipping load is NEVER figured at maximum lift height; it is calculated at maximum reach. Both SAE and ISO specifications use this as the procedure for rating loaders (articulated, skid-steer, tractors).

(The ROC is half the tipping load for wheeled machines and 35% of the tipping load for tracked machines.)
