Telehandlers are machinery that are meant to work in rough terrain, however, that doesn't mean that they can be driven without any regard for the environment. These types of machines have a much greater risk of load loss or tipping over when they are traveling on slopes.
If you do need to travel on a slope, make certain that you proceed carefully and slowly while keeping the load low. Prior to getting on the slope, downshift to 4WD and a lower gear. Using the engine brake will 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 caution.
Under any conditions, do not drive across extremely steep slopes. Descend and ascend slopes with the heavy end of the telehandler pointing up the incline. Even when the forks have no load, the machine's counterweighted rear is quite heavy; hence, it could be required to drive in reverse up slopes. Once the telehandler is carrying a cargo, the front of the unit becomes the heavy end, and you can back the machinery down the slopes.
Operator training is extremely vital on a mixed jobsite. Rear pivot machinery would usually operate on the same jobsite of coordinated steering machines, where everybody is allowed to use all of the equipment. In this instance, an individual who is used to using a coordinated steer machine can jump onto a rear-pivot machine. A really significant distinction between how these two units work depends on which part of the machinery extends outside of the turning radius.
