Rope Pulling Exercise Apparatus with Variable Resistance

摘要

A rope pulling exercise apparatus with variable resistance has a main supporting frame, a rotary cylinder assembly pivotally mounted on the main supporting frame, a rotary wheel pivotally mounted on the main supporting frame, a driving device and a resistance generating device. The rotary cylinder assembly has a pull-rope wrapped around a rotary cylinder. The driving device has a driving wheel coaxially mounted on the rotary cylinder, a driven wheel coaxially mounted on the rotary wheel, aligning with the driving wheel and being smaller than the driving wheel in radius, and a transmission belt mounted around the driving wheel and the driven wheel. The resistance generating device selectively resists rotation of the rotary wheel. The rope pulling exercise apparatus provides a user one more option on choosing fitness equipments, and increases the user's desire on exercising.
