Mobile apparatus with operating system

Mobile apparatus comprising:

• a main frame provided with displacing means;
• and
• a sub-frame connected rotatably to the main frame and an operating arm connected to the sub-frame, wherein the sub-frame is provided with a seating or standing location for a driver, operating instruments controllable by a driver, and a bus system connected to the operating instruments;
• wherein the main frame is provided with a lifting device to which an implement is connected, wherein the lifting device comprises a lifting arm, and wherein the implement is coupled to the lifting arm;
• wherein the mobile apparatus further comprises at least one drive configured for driving independently moving the lifting arm upward and downward with respect to the main frame and for operating the implement, and a control unit connected to the bus system for controlling said at least one drive on the basis of signals from the bus system such that the lifting device and the implement are independently controllable via the bus system using the operating instruments in the sub-frame such that a driver can control independently a first energy flow for moving the lifting arm upward and downward with respect to the main frame and a second energy flow for operating the implement connected to the lifting device, and
• wherein said at least one drive comprises at least one energy source and at least one motor.
