Telehandlers are heavy duty work equipments produced particularly to operate in rough environment. This however, does not mean they can be driven without consideration on rough terrain. These machines 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 slowly and carefully while keeping the load low. Prior to getting on the slope, downshift to 4WD and a lower gear. Utilizing the engine brake would actually help to control the speed of the telehandlers. Try not to turn on a slope if possible. If you must make the turn, take it as wide as possible and use extreme care.
Under any conditions, do not drive across excessively steep slopes. Descend and ascend slopes with the telehandler's heavy end pointing up the incline. Even when the forks have no load, the counterweighted rear of the machinery is fairly heavy; thus, it can be necessary 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 machine down the slopes.
Operator training is hugely essential on a mixed jobsite. Rear pivot equipment will often operate on the same jobsite of coordinated steering machinery, where everyone is allowed to operate all of the equipment. In this case, an individual who is used to utilizing a coordinated steer machine could jump onto a rear-pivot machine. A really key difference between how these two units operate depends on which part of the machinery extends outside of the turning radius.
