Abstract

A self-propelled construction machine, comprises a machine frame, on which a working unit is arranged, and comprises a drive unit for driving the working unit. An additive, in particular a urea solution for operating an exhaust gas treatment system, is provided in an operating material tank which is integrated in the fuel tank or water tank of the construction machine. The integration of the operating material tank in the fuel tank or water tank does not necessitate any modifications to the machine frame. The dimensions of the construction machine can also remain unchanged, since the fuel tank does not take up any extra space on the machine frame if the dimensions of the fuel tank or water tank are maintained.

Claims20

Dependent claims

A self-propelled construction machine, comprising:

a machine frame;
a working unit arranged on the machine frame and configured to carry out work for a building operation;
a drive unit arranged on the machine frame and configured to drive the working unit, the drive unit including at least one internal combustion engine;
a first tank formed as an integral component of the machine frame, the first tank being either a fuel tank configured to hold fuel for the at least one internal combustion engine or a water tank;
and
an operating material tank configured as an exchangeable unit removable from the first tank so that the first tank has a first capacity when the operating material tank is removed from the first tank, and a second capacity smaller than the first capacity when the operating material tank is received in the first tank, the operating material tank being configured to hold operating material.
