Abstract: A pivot-steered tandem roller for ground compaction, comprising a machine frame with an operator platform, two compaction drums which are spaced apart from one another in the longitudinal direction of the machine and are each steerably mounted on the machine frame via a pivot steering system, a drive motor, a cooler, and a fan associated with the cooler and conveying a cooling air flow, the cooler being arranged vertically above and/or in the longitudinal direction of the machine at the level of one of the compaction drums. Moreover, the invention relates to a method for operating such a pivot-steered tandem roller.

Abstract: An entertainment attraction (100) comprises remote-controlled, telepresence vehicles (204) and an environment (200) for the vehicles to traverse. The environment includes a plurality of reconfigurable portions (206). A vehicle includes an identification device (208) for providing an identifier and a camera (210) for imaging its field of view. A driver console (102) corresponding to a vehicle includes a monitor (212) for displaying the imaged field of view of the camera and a control device (214) for providing a driver-initiated control signal. A control system (218) includes detectors (220) dispersed about the environment. A detector is configured to receive the identifier or to sense the vehicle or both. The control system composes the interactions among the vehicles, the driver console, and the reconfigurable portions according to the received identifier, the sensing of the vehicle, or the driver-initiated control signal or some combination thereof.
