Abstract
A work vehicle includes a vehicle frame which is supported by first and second axles. A driver's cab, a lifting arm, and at least one electrical energy store unit are supported on the vehicle frame. The lifting arm is arranged along a longitudinal direction of the work vehicle parallel to a longitudinal axis of the vehicle frame. The driver's cab is arranged to a first side of the longitudinal axis between the two axles. The at least one energy store unit is arranged between the two axles to a second side of the longitudinal axis, which is situated opposite the first side.
Claims11
A work vehicle comprising:
- a vehicle frame which is supported by a first and a second axle;
- a driver's cab;
- a lifting arm;
- and
- at least one electrical energy store unit, wherein
- the lifting arm is arranged along a longitudinal direction of the work vehicle, wherein
- the driver's cab is arranged to a first side of a longitudinal axis of the vehicle frame between the two axles, wherein
- the at least one energy store unit is arranged between the two axles to a second side of the longitudinal axis of the vehicle frame which is situated opposite the first side of the longitudinal axis of the vehicle frame, and
- wherein
- the work vehicle is driven exclusively via electrical energy which is stored in the at least one electrical energy storage unit;
- an electrically driven hydraulic pump for powering work functions of the work vehicle, the pump being arranged on the first side of the longitudinal axis of the vehicle frame.
A work vehicle comprising:
- a vehicle frame having a longitudinal axis and front and rear end portions;
- front and rear longitudinally-spaced axles that support the vehicle frame and that extend laterally from the vehicle frame;
- a driver's cab that is supported on the vehicle frame;
- a lifting arm that is supported on the vehicle frame, the lifting arm being pivotable about a lateral axis located at the rear end portion of the vehicle frame;
- and
- at least one electrical energy store unit, wherein
- the lifting arm extends along a longitudinal direction of the work vehicle, wherein
- the driver's cab is arranged to a first side of the longitudinal axis of the vehicle frame between the two axles, wherein
- the at least one energy store unit is arranged between the two axles to a second side of the longitudinal axis of the vehicle frame which is situated opposite the first side, and wherein
- the work vehicle is exclusively driven via electrical energy which is stored in the at least one electrical storage unit;
- wherein a position of the at least one energy store unit along the longitudinal axis of the vehicle frame is nearer the rear axle than the front axle.
