A road-finishing machine for producing a paving layer from a laying material or a charger vehicle for supplying the road-finishing machine with a laying material. The road-making machine comprises a material bunker, and a pushing means fixed forward of the material bunker at a chassis, such that pushing rollers of the pushing means may dock to rear tires of a truck. The pushing rollers comprise a pair of first pushing rollers mountable in a first position in a seat of a traverse of the pushing means. Either the pushing means is expandable by at least one changeable attachment to which the first pushing rollers may be mounted in a second position further forward with respect to the first position, or the pushing means comprises a pair of second pushing rollers which may be selectively positioned forward of the first pushing rollers.

A wall surface suction travel device includes a first travel unit, a second travel unit, a joint mechanism, and an elastic mechanism. The travel units are aligned along a travel direction and are each configured to travel on a wall surface while being suctioned on the wall surface. The joint mechanism couples the travel units together such that the travel units can pivot relative to each other on a pivot axis extending in a direction that is perpendicular to both a wall surface facing direction and the travel direction. The elastic mechanism includes a first end fixed to the first travel unit, a second end fixed to the second travel unit, and an elastic member configured to be elastically deformed when one of the travel units pivots relative to the other travel unit and a distance between the first end and the second end is shortened.

Vehicle coupling assemblies suitable for facilitating a resilient coupling between a rear vehicle and a vehicle wheel on a front vehicle may include a coupling assembly arm. The coupling assembly arm may be resiliently length-variable responsive to application of a longitudinal extension force on the coupling assembly arm. A wheel engagement member may include an engagement member body rotatably carried by the coupling assembly arm. The engagement member body may be suitably sized and configured for engagement with the vehicle wheel on the front vehicle in substantially concentric relationship with respect to the vehicle wheel.
