Pivot-steered tandem roller and method for operating such rollers

A method for operating a pivot-steered tandem roller machine, comprising:

• drawing in cooling air from an outside environment of the tandem roller machine into a front machine compartment or a rear machine compartment;
• directing the cooling air downward into an engine compartment and along a longitudinal direction of the tandem roller machine;
• directing the cooling air upward into the respective other front machine compartment or rear machine compartment;
• passing the cooling air through a cooler arranged in the front machine compartment or the rear machine compartment;
• blowing out the cooling air into the outside environment of the tandem roller machine;
• and
• drawing in the cooling air through an intake duct between an operator platform and ventilation openings through which a cooling air flow conveyed by a fan exits into the outside environment of the tandem roller machine.

A pivot-steered tandem roller machine for ground compaction, comprising:

• a machine frame with an operator platform;
• two compaction drums spaced apart in a longitudinal direction of the tandem roller machine, each of which is steerably mounted on the machine frame via a pivot steering system;
• a drive motor;
• a cooler;
• a fan associated with the cooler and to convey a cooling air flow;
• wherein the cooler is arranged vertically above and/or in the longitudinal direction of the tandem roller machine at a level of one of the compaction drums;
• and
• wherein the cooler is arranged such that the cooling air flow flows through the cooler in an at least partially upward direction.
