<p>PURPOSE:To reduce vibration transmitted to a cage from a drive part so as to ensure stable high speed operation by forming an elevation drive frame in a flat box having an opened rear part, and by attaching a drive unit so that the output shaft side thereof is projected into an interior space of the elevation drive frame. CONSTITUTION:A carrier for a rack type elevator for construction, incorporates an elevation drive frame 20 which bears a rotary drive wheel 43 which is meshed with a rack S1 laid on a tower 10, and is rotated by a drive unit 43. The elevation drive frame 20 is coupled to a driven frame 30 on which a load- carrying platform or a cage 50 is supported. Further, the drive frame 20 is formed in a rigid flat box shape having an opened rear part and a front surface at which the drive unit 41 is secured, and a part of the drive unit 41 is projected into an interior space in the drive frame 20. Further, a support bed frame for the cage 50 is projected from the front lower part of the driven frame 30, and guide roller are journalled at opposite sides of the lower part thereof.</p> |
