Bolt crank
From Ratchet & Clank wiki
(Redirected from Bolt Cranks)
Bolt cranks, which could be activated with Ratchet's OmniWrench, were most often used to open doors or to activate bridges. Bolt cranks appeared in every Ratchet & Clank game.
DreadZone used these a lot to challenge their heroes into getting towards the next part of a challenge. However, they could also be found abundantly throughout the Solana and Bogon galaxies as well. Ratchet's bots could also activate these.
