Telehandlers are machinery which are designed to work in rough environment, although, that doesn't mean that they could be driven without any regard for the terrain. These kinds of machinery have a a lot greater risk of tipping over or load loss when they are traveling on slopes.
If you do need to travel on a slope, ensure that you proceed carefully and slowly while keeping the load low. Prior to getting on the slope, downshift to 4WD and a lower gear. Using the engine brake would really help to control the telehandler's speed. Try to avoid turning on a slope if possible. If you must make the turn, take it as wide as possible and use 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 cargo on the forks, the equipment's counterweighted rear is fairly heavy; thus, it could be necessary to drive backwards up slopes. When the telehandler is carrying a load, the front of the unit becomes the heavy end, and you can back the machine down the slopes.
Operator training is extremely essential on a mixed jobsite. Rear pivot machines would often operate on the same jobsite of coordinated steering machinery, where everyone is allowed to use all of the machines. In this instance, an individual who is used to using a coordinated steer machinery can jump onto a rear-pivot machine. A really significant difference between how these two units operate depends on which part of the equipment extends outside of the turning radius.
