Wondering if anyone has converted a push girder trolley to a geared one. I've got a few push style ones, the largest being the 2T one on my gantry and would like to convert it to geared with a chain drive to make it easier to move along the beam while loaded.
Looking at photos of geared models, it seems they're essentially the same as the push models but have a very basic spur gear tooth cut into the wheel flanges, and a suitable size pinion mounted between them to drive both wheels at once (as well as obviously a shaft and chainwheel etc...).

Here's an example: https://www.beaver.com.au/materials-handling/materials-handling/push-and-geared-girder-trolleys/beaver-geared-girder-trolley

Anything I'm missing?
