PURPOSE:To guide a self-propelled work carriage for operation without using rails, etc., by providing hourglass-shaped magnetic wheels which roll along a corner part of a steel material, and flat type magnetic wheels which roll on the surface of the steel material, parallelly interlocking with the former wheels rolling. CONSTITUTION:A self-propelled work carriage 1 used for construction work, etc., is parallelly interlocked with hourglass-shaped wheels 1A, 1B rolling along a corner part 14 of a magnetic steel material 9 and provided with flat type magnetic wheels 5A, 5B rolling on the surface of the magnetic steel material 9. Out of the wheels. the hourglass-shaped wheel 1A and the flat type wheel 5A are synchronizingly rolled by a driving part 3, while those wheels 1A. 1B, 5A, 5B and the driving part 3 are disposed on a frame 2 mounting work materials (not illustrated) thereon. The driving part 3, containing a motor, is formed so that its power may rotate each of the wheels 1A, 5A through a worm gear 4, each of worm wheels 12, 52. |
