Telehandlers are machinery that are meant to work in rough environment, however, that doesn't mean that they can be driven without any regard for the environment. These kinds of machinery have a a lot bigger risk of tipping over or load loss when they are traveling on slopes.
If you do have to travel on a slope, make certain 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 actually help to control the speed of the telehandlers. Try not to turn on a slope if possible. If you have to make the turn, take it as wide as possible and use extreme care.
Under any conditions, avoid driving across excessively steep slopes. Descend and ascend slopes with the telehandler's heavy end pointing up the incline. Even when the forks have no cargo, the counterweighted rear of the equipment is fairly heavy; hence, 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 would be able to back the equipment down the slopes.
On a mixed jobsite, operator training is very essential. The coordinated steering machinery, along with the rear-pivot machinery often work on the same jobsite where everyone is permitted to use all of the machinery. In this case, an individual who is used to using a coordinated steer machinery can jump onto a rear-pivot machinery. A very key difference between how these two units work depends on what part of the machinery extends outside of the turning radius.
