Cranky is a dockyard loading crane who works for the Sodor Shipping Co. at Brendam Docks.
Cranky arrived in Sodor in 1998. When he was still new, he insulted Thomas and Percy by calling them bugs. However after a strong storm and a rather hard pull of the rope by Percy, he has leaned his lesson and has reformed.
The reason why Cranky is so grumpy is because he doesn't get enough sleep at night. He one time let his anger get the best of him and knocked the whole goods shed down at Brendam Docks.
He was involved in the starting of the jet engine out of rage, which pushed Thomas down the line very fast.
Cranky can often be grumpy mostly because he doesn't get any sleep at night. He works all day and his only company is the seagulls. He is however, considered a hard worker and a valuable member of the Dockside crew. He is often annoyed by the engines and frequently looks down upon them. He says he enjoys teasing them because it makes for good working relationships but don't ask Percy if he agrees. In any case, he does help the engine out on occasion, and as said by Salty, he does have a heart.
