Abstract: In order to know the loads acting on the boom, the load measuring unit, in particular only one, is either on or in the boom, in particular fixed, or between the arm end of the boom and the head end of the working head facing it.

Abstract: In order to be able to accommodate the required number of battery modules (5)—specified in terms of their external dimensions—and in particular the number required by the customer, with good weight distribution, in the chassis gradations of diesel tractors, in particular of long cabs, when switching to a battery electric drive, different arrangements of the battery modules (5) at the front and in particular also at the rear in the chassis (2) are proposed according to the invention.

Abstract: In order to be able to supply the traction drive on the one hand and the working unit (210) on the other hand with the energy required in each case independently of one another in a purely electrically driven vehicle (200), in particular a self-travelling working machine (200), a fully electric drive unit (100) is provided which supplies both, with a planetary gear unit (1) which is driven by two separately controllable electric machines (E1, E2) and thus, considered on its own, acts as a summing gear. Because of an additional power output (NA1), which is coupled to one of the two E-machines (E1) and/or the corresponding drive input into the planetary gear (1) with a fixed transmission ratio, the working unit (210) can be supplied via this power output (NA1), while the speed of the traction drive is independently controlled via the differential speed between the sun gear (2) and the ring gear (3), which are driven by the two E-machines (E1, E2).

Abstract: In order to require as few load measuring units (50) as possible and yet always know the loads acting on the boom (3, 4) independently of the working head (2) currently attached to the boom (3, 4), the load measuring unit (50), in particular only one, is either on or in the boom (3, 4), in particular fixed, or between arm end (18a) of the boom and the head end (18b) of the working head (2) facing it.
