The ROC, rated operating capacity, is rated at half of the tipping capacity. This is the rules by which SS manufactures use. Some society or safety board set up these guidelines. Thus, if 3000 lbs will tip down the front of a toolcat or SS, the ROC is 1500 lb. It doesn't mean the machine can't lift more. Companies can't promote it as lifting more. This is why some SS can outlift other units even if they have the same ROC. It is widely known the toolcat can lift 2000 lbs but the ROC is 1500lbs. Some SS manufactures will increase the ROC with the addition of rear weight kits. I have a bobcat S300. The bobcat S250 and S300 are identical machines but the S300 has nearly 700 more lbs of weight and a 500 lb greater ROC. (2500lbs ROC vs 3000lbs ROC). Both use the same motor but the hp is turned up about 9-10hp for the S300. The S330 (ROC 3300lbs) is the same base machine and hydraulics but has a different motor, more hp and even more weight. This practice is used by most manufactures, not just bobcat. I have a 36" tree spade and will soon be adding stabilizers to the back of my S300. Each stabilizer weighs about 200 lbs and has additional steel weights to increase up to another 400 lbs per stabilizer. 1200 lbs total additional rear end weight. Great stability for lifting heavy stuff. However, if I leave all the rear weight on, I won't be able to go up any type of grade unless I have something on the front - too rear end heavy. In fact, I will be moving my rear axles weights to the front axle to help with this problem. In hindsight, a S250 would have been cheaper to buy and just add my weight to make it S300 or S330. S250 weighs 7,723 lbs, S300 weighs 8,448 lbs and S330 weighs 9,185 lbs.
Strangely, CUT FELs can lift much more than the machine tipping capacity. CUT FEL for most tractors can lift the back of the tractor. Maybe it is because the FEL is not part of the base machine. Maybe ag use has exemptions. Tractors manufactures also usually state that FEL use should have rear end weights and ballast in the back when using FEL.
