Telehandlers are heavy duty work machines produced specially to operate in rough terrain. This however, does not mean they can be driven without regard on rough terrain. These 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 equipment while also keeping the load low. Downshift to 4WD and a lower gear, prior to getting on the slope. Utilizing the engine brake would really 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.
Always try not to drive across extremely 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 counterweighted rear of the machinery is quite heavy; hence, 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 will be able to back the equipment down the slopes.
Operator training is hugely vital on a mixed jobsite. Rear pivot machinery would normally operate on the same jobsite of coordinated steering equipment, where everybody is allowed to operate all of the machinery. In this case, a person who is used to using a coordinated steer equipment can jump onto a rear-pivot machine. A very significant difference between how these two units work has much to do with which part of the machinery extends outside of the turning radius.
