<p>The truck has a pair of wheel cases (26) provided with additional wheel holders (20) for additional wheels (22). A set of assembly interfaces for assembly of the wheel cases are provided at frames (12) and/or the wheel cases. The wheel cases have another set of assembly interfaces complementary to the former set of interfaces and releasably connected with the former set of interfaces so that a tandem axis arrangement is formed. The additional wheels lie on a common rotational axis that is parallel to a rotational axis of wheels (16) in the tandem axis arrangement.</p> |
