Telehandlers are machinery which are meant to operate in rough terrain, however, that doesn't mean that they can be driven without any consideration for the environment. These kinds of machines have a much greater risk of tipping over or load loss 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 will actually help to control the speed of the telehandlers. Try to avoid turning on a slope if possible. If you need to make the turn, use extreme caution and take it as wide as possible.
Under any circumstances, do not drive across extremely steep slopes. Ascend and descend slopes with the heavy end of the telehandler pointing up the incline. Even when the forks have no load, the machine's counterweighted rear is quite heavy; therefore, it can be required to drive in reverse up slopes. Once the telehandler is carrying a cargo, the front of the unit becomes the heavy end, and you could back the machine down the slopes.
On a mixed jobsite, operator training is really essential. The coordinated steering equipment, along with the rear-pivot equipment normally operate on the same jobsite where everyone is allowed to utilize all of the machines. In this case, an individual who is used to using a coordinated steer equipment could jump onto a rear-pivot machinery. A really key distinction between how these two units operate depends on what part of the equipment extends outside of the turning radius.
