Telehandlers are heavy duty work machines produced specifically to work in rough terrain. This however, does not mean they could be driven without consideration on rough environment. These equipments have a much greater risk of load loss or tipping over when they are traveling on slopes.
If you do have to travel on a slope, make sure that you proceed carefully and slowly while keeping the load low. Before getting on the slope, downshift to 4WD and a lower gear. Using the engine brake would actually help to control the telehandler's speed. Try not to turn on a slope if possible. If you must make the turn, utilize extreme care and take it as wide as possible.
Under any circumstances, do not drive across extremely steep slopes. Descend and ascend slopes with the heavy end of the telehandler pointing up the incline. Even when there is no load on the forks, the counterweighted rear of the machinery is fairly heavy; therefore, it could be required to drive in reverse up slopes. Once the telehandler is carrying a cargo, the front of the unit becomes the heavy end, and you can back the equipment down the slopes.
On a mixed jobsite, operator training is very essential. The coordinated steering equipment, along with the rear-pivot machines normally operate on the same jobsite where everyone is permitted to utilize all of the machines. In this instance, a person who is used to utilizing a coordinated steer equipment can jump onto a rear-pivot equipment. A really key distinction between how these two units operate has a lot to do with what part of the machine extends outside of the turning radius.
