Ladders improved

When we are climbing or afraid of climbing highly, we can buckle the haddle position and make the rear ladder slide down along the track,the track distance is just a half of the original bar distance, which makes the ladder slide to the half original bar distance and stop instantly.And it is better for us to climb because of reducing the every step distance and fear.
