Which is the best way to negotiate kerbs on a fork lift truck?

The only way is to find a curb cut and drive on it. If you drive a forklift straight across a curb you'll probably high-center it; if you approach at an angle you could overturn the machine. At an angle. The forklift isn't going to flip unless you slam into the incline going 11-12mph. Slow down and go at an angle and you will not get hung. Depending on the incline or weight of the freight, turn around and go in reverse due to 8,000+ lbs being on the back of the motor.Do not go straight on unless you have another lift to pull you off. I have a BA from Ole Miss and have been driving a lift all my life.Obviously you have to approach at ur own risk. Trying to drive along the side of a mountain isn't going to work
