Telehandlers are heavy duty work machines produced specifically to work in rough terrain. This however, does not mean they can be driven without consideration on rough environment. These equipments have a much 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 slowly and carefully while keeping the load low. Prior to getting on the slope, downshift to 4WD and a lower gear. Using the engine brake will 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 utilize extreme caution.
Under any circumstances, avoid driving across extremely steep slopes. Ascend and descend slopes with the heavy end of the telehandler pointing up the incline. Even when there is no cargo on the forks, the counterweighted rear of the equipment is quite heavy; hence, it can be required to drive in reverse up slopes. When 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 machines will often operate on the same jobsite of coordinated steering equipment, where everyone is allowed to operate all of the equipment. In this instance, a person who is used to using a coordinated steer equipment can jump onto a rear-pivot machine. A really significant distinction between how these two units work depends on what part of the machine extends outside of the turning radius.
