Telehandlers are machines which are designed to operate in rough terrain, however, that doesn't mean that they could be driven without any consideration for the environment. These types of equipments have a a lot bigger risk of load loss or tipping over when they are traveling on slopes.
When traveling on a slope, make certain 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. Using the engine brake will really help to control the speed of the telehandlers. Try not to turn on a slope if possible. If you must make the turn, take it as wide as possible and utilize extreme caution.
Under any circumstances, do not drive across extremely steep slopes. Descend and ascend slopes with the heavy end of the telehandler pointing up the incline. Even when there is no cargo on the forks, the counterweighted rear of the machine is quite 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 can back the machine down the slopes.
Operator training is hugely essential on a mixed jobsite. Rear pivot machinery would usually operate on the same jobsite of coordinated steering equipment, where everybody is permitted to use all of the machinery. In this case, an individual who is used to using a coordinated steer equipment could jump onto a rear-pivot machinery. A very significant difference between how these two units operate has much to do with what part of the machine extends outside of the turning radius.
