Telehandlers are heavy duty work machines made particularly to work in rough environment. This however, does not mean they can be driven without regard on rough environment. These types of machines have a a lot greater 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 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 help to control the telehandler's speed. Try not to turn on a slope if possible. If you have to make the turn, use extreme care and take it as wide as possible.
Always try to avoid driving across very steep slopes. Utilize the heavy end of the telehandler pointing up the incline, when descending and ascending slopes. Even when there is no cargo on the forks, the equipment's counterweighted rear is quite heavy; hence, it can be necessary 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 machine down the slopes.
Operator training is extremely important on a mixed jobsite. Rear pivot equipment will usually operate on the same jobsite of coordinated steering equipment, where everybody is permitted to utilize all of the machinery. In this case, a person who is used to using a coordinated steer machine could jump onto a rear-pivot equipment. A really key distinction between how these two units operate has a lot to do with which part of the equipment extends outside of the turning radius.
