ABSTRACT:
A rock climbing apparatus including a support stand on which a main body frame is mounted. The main body frame has two lateral columns, several transverse support beams and several longitudinal support columns built between the lateral columns to serve as a support skeleton. A rotary mechanism is arranged in the main body frame, including at least two chains in parallel to the length of the main body frame, multiple transverse slats in parallel to the width of the main body frame and a power supply for driving the chains to circularly revolve. The longitudinal support columns of the main body frame are arranged in a position where the chains are positioned. Each longitudinal support column has a rib rail, whereby the link shafts of the chains are slidably leant on the rib rail. The transverse slats are fixed on the chains and immediately adjacent to each other. The chains are positioned near the middle of the transverse slats. The transverse slats can circularly revolve along the lateral columns. Several rocks are locked on one face of each transverse slat distal from the chains for a user to climb.
