Electric drive of mobile apparatus
First Claim
1. A mobile apparatus comprising a main frame with displacing means, a sub-frame arranged rotatably relative to the main frame, wherein the rotatable sub-frame comprises operating instruments for a driver, an operating arm connected to the sub-frame, a first drive configured to drive the displacing means, a second drive configured to drive the operating arm, and a control system, connected to the operating instruments, for controlling the first and second drive, wherein the first drive comprises at least one electric motor such that the first drive is substantially electrical;
- said mobile apparatus further comprising at least one energy storage unit for storing and supplying electrical energy to the at least one electric motor, a generator operatively connected to the at least one energy storage unit, and a combustion engine operatively connected to the generator, wherein the combustion engine and generator are configured to supply electrical energy to the at least one energy storage unit, said generator being placed in the main frame.
