Telehandlers are heavy duty work machines made specifically to work in rough terrain. This however, does not mean they could be driven without regard on rough environment. These kinds of machines have a a lot greater risk of tipping over or load loss when they are traveling on slopes.
If you do need to travel on a slope, make sure that you proceed carefully and slowly while keeping the load low. Before getting on the slope, downshift to 4WD and a lower gear. Utilizing the engine brake would help to control the telehandler's speed. Try to avoid turning on a slope if possible. If you must make the turn, use extreme care and take it as wide as possible.
Always try to avoid driving across extremely steep slopes. Utilize the telehandler's heavy end pointing up the incline, when ascending and descending slopes. Even when there is no load on the forks, the counterweighted rear of the machinery is fairly heavy; thus, it could be necessary to drive backwards up slopes. When the telehandler is carrying a load, the front of the unit becomes the heavy end, and you would be able to back the machine down the slopes.
Operator training is extremely important on a mixed jobsite. Rear pivot equipment would usually operate on the same jobsite of coordinated steering machines, where everyone is permitted to utilize all of the machinery. In this case, a person who is used to using a coordinated steer equipment can jump onto a rear-pivot machinery. A very significant distinction between how these two units operate depends on what part of the equipment extends outside of the turning radius.
