Telehandlers are heavy duty work equipments produced particularly to work in rough environment. This however, does not mean they could be driven without regard on rough terrain. These types of machines have a a lot greater risk of tipping over or load loss when they are traveling on slopes.
If you do have 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, take it as wide as possible and use extreme caution.
Under any circumstances, do not drive across excessively steep slopes. Descend and ascend slopes with the telehandler's heavy end pointing up the incline. Even when there is no cargo on the forks, the machine's counterweighted rear is fairly heavy; therefore, it can be necessary to drive in reverse up slopes. When the telehandler is carrying a load, the front of the unit becomes the heavy end, and you can back the machine down the slopes.
Operator training is hugely important on a mixed jobsite. Rear pivot equipment will usually operate on the same jobsite of coordinated steering equipment, where everybody is allowed to use all of the machines. In this case, a person who is used to utilizing a coordinated steer machinery could jump onto a rear-pivot machine. A really significant difference between how these two units operate depends on which part of the machine extends outside of the turning radius.
