The Four Stage Low-Side Cascading Kit utilizes 1121 Series Low-Side U-Channel as the framework of this very smooth and stable cascading kit. Ball bearings in every stage minimize friction while acetal side plates assist in guiding the stages as they extend and retract. The v-groove pulleys, synthetic cable and dual-spool pulley included in the kit provide a reliable drive that is powered both in the extension and retraction.

Use the kit in any orientation, whether you’re reaching up or out. The maximum travel (difference between retracted and extended) is an impressive 752mm (just shy of 30”) while measuring only 317.5mm (12.5”) tip to toe in the retracted state. The mechanical stops can be adjusted every 8mm on each stage if you wish to tailor the travel to your specific application. If you choose to do-so, limiting lower stages will yield slightly faster transit times given the upper stages have less mass moving along with them.

The kit comes with all the necessary pieces, minus the motor, to get you up and going. The included 32mm clamping mounts are compatible with the goBILDA 5202 Series Yellow Jacket Gear Motors. Tailor your travel speed with the various ratios we offer. The included pulley has a diameter of 38mm (1.5”) which yields 120mm (4.75”) of travel per rotation. Given the max travel of 752mm, it takes approximately 6.25 rotations of the motor shaft to reach full extension. The 13.7:1 ratio (435 RPM) is the fastest that we recommend, as it’s able to fully extend the four stages in about 1 second! With such a fast potential transit speed it’s recommended to utilize the encoder on the 5202 motor so you can start and stop your cascading kit at the limits of the travel.
