BB-4 Baby Bunker

The BB-4 builds on the BB-2 by giving the operator a little more breathing room while remaining firmly in the compact-entry end of the range. It is still a buffer system rather than a true autonomy-driven storage solution, but the increase in capacity reduces intervention frequency and makes the system easier to live with.

This is a practical low-cost step for sites that want automation benefits without moving into a larger bunker or silo format.

The BB-4 makes sense where:

• existing dust extraction must remain in place
• floor space is tight
• a low-cost entry into automation is required

Compared with the BB-2, it provides more room for the system to breathe before attention is needed again. That is its value: not a change in system philosophy, but a meaningful reduction in operator friction.

The BB-4 is commonly paired with WA75 and WA150 systems where the site wants a compact, economical buffer that improves handling without moving into a more infrastructure-heavy storage format.
