A catch apparatus for a loading carriage on an inclined drift elevator mounted on a stand which forms an inclined track and extends from one level to another level. The loading carriage is connected to a pulling means which moves the carriage on the track. The catch apparatus comprises a speed sensing unit coupled to a pair of carriage wheels and a locking unit provided with catch members, the locking unit being actuated by the speed sensing unit when the wheels exceed a predetermined rotary speed to pivot a catch member toward the track where it engages a reinforcing element on the track rail to arrest the carriage. |
