This utility model discloses a double-pulley device for a stair climber, relating to the field of fitness equipment and applied to a stair climber. It includes a dual-pulley resistance source with a first drive wheel and a second drive wheel; a first pulley assembly including a first pulley and a first belt, the first belt coupling the first drive wheel to a drive shaft; and a second pulley assembly including a second pulley and a second belt, the second belt coupling the second drive wheel to a drive shaft. The first pulley assembly is configured for high-friction transmission; the second pulley assembly is configured for low-friction transmission, with its friction being less than that of the first pulley assembly. This allows it to provide a buffering damping force to the drive shaft by slipping when the first belt fails. During normal operation, the device operates automatically. However, when the first belt slips off or fails, the friction between the second pulley and the second belt provides sufficient damping force to slow the descent of the stair treads, thus providing a buffering and protective function.
