Telehandlers are heavy duty work machines produced particularly to work in rough environment. This however, does not mean they could be driven without regard on rough environment. These machines 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, 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 will help to control the speed of the telehandlers. Try not to turn on a slope if possible. If you need to make the turn, use extreme care and take it as wide as possible.
Always try not to drive 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 machinery is quite heavy; thus, it could be required to drive backwards up slopes. When the telehandler is carrying a load, the front of the unit becomes the heavy end, and you could back the machinery down the slopes.
On a mixed jobsite, operator training is really essential. The coordinated steering machines, along with the rear-pivot machines often operate on the same jobsite where everyone is permitted to utilize all of the machines. In this case, a person who is used to utilizing a coordinated steer equipment could jump onto a rear-pivot equipment. A very key difference between how these two units work has much to do with what part of the machine extends outside of the turning radius.
