What is best for a tall conveyer belt?

[John Retkowski]

Some things you'll want to take into consideration are:

What orientation you want to pick up the totes in. I'm assuming long ways/vertically, but if you also want to pick it up wide/horizontally you'll have to account for that and probably won't be able to pursue a long base.

Where the majority of your necessary weight is. Things like electrical systems, motors, and the battery should be weighed and balanced against the conveyor (with and without the additional weight ranges of totes.)

Something you also may want to consider is an extending device going away from the pickup/conveyor side to provide extra weight after the totes are picked up. At a meeting one of our mentors talked about using a pnuematic cylinder in a previous year to extend the battery to a different point within the frame to provide better counterweight.

In conclusion I think It's entirely possible and feasible to go with a square frame as long as everything is correctly balanced.
