The RP70A can be used with the battery powered pump and optional transportation and storage frame for easy mobilisation/demobilisation. The stressor is interchangeable with other type of powerpacks. The RP70A adjusts the gap between rail ends for rail stressing, rail welding, repairing rail failures and servicing insulators.
