Telehandlers are heavy duty work machines made specially to work in rough terrain. This however, does not mean they could be driven without regard on rough environment. These kinds of machinery have a a lot greater risk of load loss or tipping over when they are traveling on slopes.
When traveling on a slope, make sure 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 would help to control the telehandler's speed. Try to avoid turning on a slope if possible. If you need to make the turn, take it as wide as possible and utilize extreme caution.
Always try to avoid driving across excessively steep slopes. Use the heavy end of the telehandler pointing up the incline, when ascending and descending slopes. Even when there is no load on the forks, the equipment's counterweighted rear is fairly heavy; thus, it can 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 machine down the slopes.
Operator training is extremely important on a mixed jobsite. Rear pivot machines will normally operate on the same jobsite of coordinated steering equipment, where everybody is allowed to operate all of the machines. In this instance, a person who is used to operating a coordinated steer machine can jump onto a rear-pivot machinery. A very key distinction between how these two units operate depends on what part of the equipment extends outside of the turning radius.
