CONSTITUTION: Multipurpose spot equipment facilitating rotation and movement includes an upper plate (11), a lower lateral plate, a plurality of rollers, a plurality of bearing rollers, a lower bolt, an upper bolt, a hinge assembly, and a coupling member. The upper plate includes a plurality of bolt insertion holes and flat top surface. The rectangular lower lateral plate of which the top and the bottom are opened includes upper and lower bolt guide slot holes of vertical two stages on both lateral surfaces. The roller is arranged inside the lower lateral plate and rolled on the ground surface. At least one among the bearing rollers is arranged between the rollers to be parallel, thereby preventing a contact of the rollers. The lower bolt is inserted into the lower bolt guide slot hole and joined to both end portions of the roller.
