Telehandlers are equipments that are designed to operate in rough terrain, although, that doesn't mean that they could be driven without any consideration for the environment. These machines have a much greater risk of load loss or tipping over when they are traveling on slopes.
When traveling on a slope, make sure that you move slowly with the machine while also keeping the load low. Downshift to 4WD and a lower gear, before getting on the slope. Utilizing the engine brake would really 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.
Always try to avoid driving across very steep slopes. Use the telehandler's heavy end pointing up the incline, when ascending and descending slopes. Even when the forks have no load, the counterweighted rear of the machine is fairly heavy; therefore, it could be required to drive in reverse up slopes. When the telehandler is carrying a cargo, the front of the unit becomes the heavy end, and you would be able to back the equipment down the slopes.
Operator training is extremely important on a mixed jobsite. Rear pivot equipment will usually operate on the same jobsite of coordinated steering machinery, where everyone is allowed to use all of the machinery. In this instance, a person who is used to utilizing a coordinated steer machinery could jump onto a rear-pivot machinery. A very key distinction between how these two units work depends on what part of the machinery extends outside of the turning radius.
