SELF-PROPELLING PLATFORM MOVABLE FENCE

PROBLEM TO BE SOLVED: To provide a self-propelling platform movable fence capable of freely traveling without being affected by snow, ice or the like on a platform. SOLUTION: A floor unit 20 provided with rails 21 disposed along a platform and buried in the end of a track side on the platform is installed with heaters 51 to 54. The heaters 51 to 54 extend in the direction along the platform. In other words, the floor unit 20 is constituted to include a plurality of heaters inside the cross section of which direction of the normal is one along the platform. Therefore, the self-propelling platform movable fence houses a door body 2 in such a manner that the door body 2 freely protrudes/retracts and makes movable door pocket bodies 1 travel on the rails 21 through wheels 3 by heating the rails 21 by the heaters 51 to 54 to remove snow, ice or the like.
