#PartQtyWhat it does
1 Crank Shaft 1× Rotating axle that converts the stepping motion into rotational energy, geared to slow speed for fluid movement.
2 Drive Cable 2× Steel-braided cable that transmits force from the crank to the link arms.
3 Pulley 3× Sealed bearing pulleys that route the cable and adjust the mechanical advantage of the drive.
4 Link Arm 2× Rigid steel arm that converts rotational input into linear vertical motion of the foot platform.
5 Ball Bearing 8× Crank and pivot bearings
6 Step Connector Rod 2× Rod linking each link arm to its foot platform, transferring upward force.
