CAN in hydraulics for forestry machinery with Tier 4- continued
Hydrostatic fan drives designed for the harsh conditions of forestry take over management of the cooling circuit on forestry machinery. They keep the combustion engine at an ideal operating temperature regardless of engine speed. The fan drives cool water, oil, charge air as well as the returned exhaust gas at the same time. The control electronics communicate with numerous sensors via CAN and steplessly varies the fan speed independently of the diesel engine speed. In reversing operation the fan changes its direction of rotation to prevent dust and particles from accumulating in the radiator and allowing the engine to overheat. The dirt is blown in the opposite direction, carrying it outside. The standstill option turns the fan completely off at startup or when outside temperatures are very low. The combustion engine thus reaches its operating temperature sooner and thus harmful emissions are reduced.
The company’s LT13H space-saving power brake system consists of a hydraulically actuated two-circuit compact brake block with integrated accumulator charging valve and electrically actuated hand brake function. This reduces system costs with its flexible installation possibilities and minimal piping and cabling requirements, and is suitable for movable rotate- and lift cabins. Undesired heat and noise are prevented from entering the cabin while sensitive control on differential grades is increased.
