Telehandlers are machines that are designed to work in rough terrain, although, that doesn't mean that they could be driven without any consideration for the environment. These kinds of machines have a much bigger risk of load loss or tipping over when they are traveling on slopes.
If you do need to travel on a slope, ensure that you proceed slowly and carefully while keeping the load low. Prior to getting on the slope, downshift to 4WD and a lower gear. Using the engine brake would 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.
Always try to avoid driving across very steep slopes. Utilize the heavy end of the telehandler pointing up the incline, when ascending and descending slopes. Even when the forks have no cargo, the counterweighted rear of the equipment is fairly heavy; thus, it could 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 will be able to back the machinery down the slopes.
On a mixed jobsite, operator training is really important. The coordinated steering machines, along with the rear-pivot equipment often work on the same jobsite where everybody is permitted to use all of the machines. In this instance, a person who is used to using a coordinated steer machinery could jump onto a rear-pivot machinery. A really key difference between how these two units work has a lot to do with what part of the machine extends outside of the turning radius.
