Telehandlers are machinery which are meant to work in rough terrain, although, that doesn't mean that they could be driven without any regard for the environment. These kinds 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 machinery while also keeping the load low. Downshift to 4WD and a lower gear, prior to 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 need to make the turn, take it as wide as possible and utilize extreme care.
Under any conditions, avoid driving across extremely steep slopes. Ascend and descend slopes with the heavy end of the telehandler pointing up the incline. Even when there is no cargo on the forks, the machine's counterweighted rear is fairly heavy; thus, it can be required to drive backwards up slopes. When the telehandler is carrying a cargo, the front of the unit becomes the heavy end, and you can back the equipment down the slopes.
On a mixed jobsite, operator training is really important. The coordinated steering machines, along with the rear-pivot machinery often work on the same jobsite where everybody is allowed to use all of the machinery. In this instance, a person who is used to using a coordinated steer equipment could jump onto a rear-pivot equipment. A really significant distinction between how these two units work has much to do with which part of the equipment extends outside of the turning radius.
