Telehandlers are equipments which are meant to work in rough terrain, however, that doesn't mean that they could be driven without any consideration for the terrain. These machinery have a a lot bigger risk of tipping over or load loss 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, before getting on the slope. Utilizing the engine brake will help to control the speed of the telehandlers. Try not to turn on a slope if possible. If you must make the turn, utilize extreme caution and take it as wide as possible.
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 load, the machine's counterweighted rear is fairly heavy; therefore, it could be necessary to drive backwards up slopes. Once the telehandler is carrying a cargo, the front of the unit becomes the heavy end, and you could back the machinery down the slopes.
Operator training is extremely important on a mixed jobsite. Rear pivot machines will usually operate on the same jobsite of coordinated steering machines, where everyone is allowed to use all of the machinery. In this case, a person who is used to operating a coordinated steer equipment could jump onto a rear-pivot machine. A very significant difference between how these two units operate depends on what part of the machinery extends outside of the turning radius.
