Patent attributes
A movable bearing device includes a base, a plurality of casters, and a plurality of foot pads. The casters are provided on the bottom of the base. The foot pads are movably connected to the bottom of the base in a way that the foot pads are moved upwards and downwards with respect to the base. When the foot pads are moved downwards until their bottom surfaces each have a height equal to or lower than the bottom edges of the casters, the movable bearing device is supported on the ground by means of the foot pads, such that the movable bearing device cannot be moved. When the foot pads are moved upwards until their bottom surfaces each have a height higher than the bottom edges of the casters, the movable bearing device can be moved by means of the casters so as to facilitate the handling work.
