At the same time, different numbers of counterweight blocks 18 can be lifted by extending the positioning column 32 into the positioning holes 29 on different counterweight blocks 18, thereby facilitating the simulation of different load weights on the stair climber.

After that, the operator pulls the positioning frame 31 to make the positioning frame 31 move in the positioning groove, and then the operator aligns the positioning column 32 with the positioning hole 29 on the counterweight block 18 and extends it into the positioning hole 29. The counterweight block 18 can then be lifted by moving the wire rope 16. At the same time, the positioning of different counterweight blocks 18 can be achieved by extending the positioning column 32 into the positioning holes 29 on different counterweight blocks 18. The same number of counterweights 18 are lifted, which makes it easier to simulate different load weights on the stair climbing machine. Then the operator controls the stair climbing machine to work.
