Telehandlers are machines which are designed to work in rough environment, however, that doesn't mean that they can be driven without any consideration for the environment. These types of machinery have a much greater risk of load loss or tipping over when they are traveling on slopes.
If you do have to travel on a slope, make certain that you proceed slowly and carefully while keeping the load low. Prior to getting on the slope, downshift to 4WD and a lower gear. Utilizing the engine brake would actually help to control the telehandler's speed. Try not to turn on a slope if possible. If you must make the turn, take it as wide as possible and utilize extreme care.
Under any circumstances, avoid driving across excessively steep slopes. Descend and ascend slopes with the heavy end of the telehandler pointing up the incline. Even when the forks have no cargo, the counterweighted rear of the equipment is fairly heavy; therefore, it could be required to drive backwards up slopes. Once the telehandler is carrying a load, the front of the unit becomes the heavy end, and you can back the machine down the slopes.
On a mixed jobsite, operator training is very important. The coordinated steering machines, along with the rear-pivot machinery usually operate on the same jobsite where everybody is permitted to operate all of the equipment. In this instance, a person who is used to operating a coordinated steer machinery can jump onto a rear-pivot machine. A very key distinction between how these two units operate has a lot to do with which part of the equipment extends outside of the turning radius.
