Hammerzin, please don't encourage people to do what you did. Whether you are in a commercial setting or not, you still have life and limb to lose. There is a good reason pneumatic tired machines are dimensionally larger than their cushion-tired counterparts. There is also a good reason that specification plates exist. You may have gone five years without snapping a lift chain and shattering your skull lifting loads heavy enough to lift the back end of your forklift up, but it only has to happen once to end your life. Please stop abusing forklifts and work safe, you have loved ones who want to see you come home.
