FEATURES
 The Rail Rapper consists of a tractor to provide traction for a controlled work speed and the rail rapper unit. When the machine is heating the rail during the work mode, the operator walks beside the machine. The rail rapper strikes the rail head with an oscillating hammer so as to free the movement of the track as it  lengthens due to increased temperature. During the travel or transportation mode, the rapper is raised clear of the track.
