Telehandlers are equipments that are designed to operate in rough environment, however, that doesn't mean that they can be driven without any consideration for the terrain. These types of equipments have a a lot greater risk of load loss or tipping over when they are traveling on slopes.
When traveling on a slope, make certain that you move slowly with the machine while also keeping the load low. Downshift to 4WD and a lower gear, prior to getting on the slope. Using the engine brake will help to control the telehandler's speed. Try not to turn on a slope if possible. If you need to make the turn, take it as wide as possible and use extreme caution.
Always try to avoid driving across very steep slopes. Utilize the telehandler's heavy end pointing up the incline, when descending and ascending slopes. Even when the forks have no load, the machine's counterweighted rear is quite heavy; hence, it can be necessary to drive backwards up slopes. When the telehandler is carrying a cargo, the front of the unit becomes the heavy end, and you could back the machine down the slopes.
On a mixed jobsite, operator training is really essential. The coordinated steering equipment, along with the rear-pivot equipment often work on the same jobsite where everybody is permitted to utilize all of the machinery. In this case, a person who is used to operating a coordinated steer equipment could jump onto a rear-pivot equipment. A very significant difference between how these two units work has much to do with which part of the machine extends outside of the turning radius.
