Telehandlers are heavy duty work machines made specifically to operate in rough terrain. This however, does not mean they can be driven without regard on rough environment. These kinds of equipments have a much bigger 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, prior to getting on the slope. Utilizing the engine brake would help to control the speed of the telehandlers. Try to avoid turning on a slope if possible. If you must make the turn, utilize extreme care and take it as wide as possible.
Under any circumstances, do not drive across excessively steep slopes. Ascend and descend slopes with the heavy end of the telehandler pointing up the incline. Even when there is no load on the forks, the equipment's counterweighted rear is quite heavy; therefore, it can be necessary to drive backwards up slopes. Once the telehandler is carrying a load, the front of the unit becomes the heavy end, and you would be able to back the machine down the slopes.
On a mixed jobsite, operator training is very essential. The coordinated steering equipment, along with the rear-pivot machines often operate on the same jobsite where everybody is permitted to operate all of the machines. In this instance, 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 operate depends on which part of the equipment extends outside of the turning radius.
