Telehandlers are machinery that are designed to work in rough environment, although, that doesn't mean that they could be driven without any regard for the environment. These kinds of equipments have a much greater risk of tipping over or load loss when they are traveling on slopes.
If you do need to travel on a slope, make certain that you proceed slowly and carefully while keeping the load low. Before getting on the slope, downshift to 4WD and a lower gear. Using the engine brake will actually help to control the speed of the telehandlers. Try not to turn on a slope if possible. If you must make the turn, utilize extreme care and take it as wide as possible.
Always try to avoid driving across excessively steep slopes. Use the heavy end of the telehandler pointing up the incline, when descending and ascending slopes. Even when the forks have no cargo, the equipment's counterweighted rear is quite heavy; thus, it could be required to drive backwards 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 machine down the slopes.
On a mixed jobsite, operator training is really essential. The coordinated steering equipment, along with the rear-pivot machines normally work on the same jobsite where everyone is permitted to utilize all of the equipment. In this instance, a person who is used to operating a coordinated steer machinery could jump onto a rear-pivot machinery. A very key distinction between how these two units work depends on which part of the machinery extends outside of the turning radius.
