Bought and received my hoist and now awaiting some warmer weather to install it. I've read some comments in other threads about the size of the boards for the ceiling joists and thus brings my question for my application. My joists run in what the directions call the "alternate setup" meaning they run from side to side instead of front to back. The garage is drywalled. Froze my fingers long enough to get up there and the joists are 2x4s. Beyond the 2x6s that are called for is any extra support going to be needed to install the hoist?
