Transverse moving target system for indoor and outdoor use is track-guided and moves in straight lines. This system can be preset as a transverse or sideways moving target in the shooting gallery, to replicate a shooting target across an open area. The length of railway that carries the target system can be determined by the field. The actuating speed of electromotor can be adjusted, and the remote control can be realized through computers/controllers. According to the classifications of rapid-fire targets, when shooting, the target can perform such motions as popping up, side turning and flipping up, apart from transverse movement.
