ABSTRACT:
A trolley includes a track having first and second ends. A pivot is located between the first and second ends of the track so that movement of the first end of the track causes opposite movement of the second end of the track. A counterweight is located near the first end of the track so as to apply downward force. A trolley is movable along a portion of the track located between the pivot and the second end of the track. The trolley has a handle or carriage for a user. The combined weight of the user and the trolley overcomes the counterweight so as to move the second end of the track downward causing the trolley to move along the track toward the second end of the track. The counterforce is sufficient to move the second end of the track upward and to return the trolley to the starting position when the weight of the user is released from the trolley. The trolley moves between a first platform located near the starting position and a second platform lower than the first platform.
