Telehandlers are machines which are meant to operate in rough environment, although, that doesn't mean that they could be driven without any regard for the environment. These kinds of machines have a much bigger risk of tipping over or load loss when they are traveling on slopes.
If you do need to travel on a slope, ensure that you proceed carefully and slowly while keeping the load low. Prior to getting on the slope, downshift to 4WD and a lower gear. Utilizing the engine brake would really help to control the speed of the telehandlers. Try to avoid turning on a slope if possible. If you need to make the turn, take it as wide as possible and utilize extreme caution.
Under any circumstances, do not drive across extremely steep slopes. Ascend and descend slopes with the telehandler's heavy end pointing up the incline. Even when there is no cargo on the forks, the counterweighted rear of the machine is fairly heavy; hence, it can be necessary to drive in reverse up slopes. Once the telehandler is carrying a cargo, the front of the unit becomes the heavy end, and you could 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 normally work on the same jobsite where everybody is allowed to operate all of the machines. In this instance, a person who is used to operating a coordinated steer machine could jump onto a rear-pivot machinery. A very significant distinction between how these two units work has much to do with which part of the machinery extends outside of the turning radius.
