Self-powered transport carriage for driving on e.g. ceiling surface for transportation of cameras to measure objects, has crawler tracks providing grip to carriage on surfaces to be driven for downwardly moving carriage to surfaces

摘要

The carriage has two crawler tracks (4) formed from flexible and stiff belts. A sufficient level of wear-resistant and resilient material made structure is applied on the belts, where the structure consists of intersecting bars. The crawler tracks provide grip to the carriage on surfaces to be driven for downwardly moving the carriage to the surfaces. Multiple cavities are inwardly evacuated under a slider (6) during driving operation, where the cavities are ventilated during evacuation process.
