Telehandlers are heavy duty work equipments made specifically to work in rough terrain. This however, does not mean they could be driven without regard on rough terrain. These kinds of machinery have a much 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. Using the engine brake will really 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 utilize extreme care.
Always try to avoid driving across extremely steep slopes. Use 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; therefore, it could be required to drive in reverse up slopes. When the telehandler is carrying a load, the front of the unit becomes the heavy end, and you will be able to back the equipment down the slopes.
On a mixed jobsite, operator training is really important. The coordinated steering equipment, along with the rear-pivot equipment usually work on the same jobsite where everybody is permitted to operate all of the machines. In this case, a person who is used to utilizing a coordinated steer equipment can jump onto a rear-pivot machine. A really significant difference between how these two units work depends on what part of the machine extends outside of the turning radius.
