Switched from manual greasing to an automatic lube system on my tower crane last month
The difference in boom tip wear is night and day after 60 hours of operation, and I'm wondering if anyone else has seen the same kind of improvement with their rigs?

Caught a podcast with a mechanical engineer for a big rental outfit, and he was saying the same thing. He claimed their cranes on auto lube systems showed almost zero galling on the boom tip sheaves after a full season. Manual greasing just can't keep up on a 400 hour job, especially when operators forget to pump it mid-shift.

Pull the grease gun on a 400 hour job and watch the operator just nod at you like he's gonna do it, then find out three shifts later he was "busy." Auto lube systems don't take smoke breaks or forget mid-crank. My buddy runs a Liebherr on a high rise and his boom tip sheaves look like they just came off the showroom floor after six months, meanwhile the guy next lot with manual greasing is already swapping rollers because they welded themselves to the pins. It's almost funny how much money we waste pretending guys will actually pump grease every hour when they're hanging 200 feet up.
