Question by: Stan T on Jun 16, 2025, 9:08 PM

Got a transit mixer that's been eating motors alive, wondering if the M39 is tough enough to hold up to that kind of punishment day in and day out?

Answer by: Customer Support on Jun 18, 2025, 6:10 PM

Cast iron construction goes a long way in high-cycle work like that. The M39 is rated for 397 Nm of torque and pulls up to 67.3 gallons per minute, so it's built with the load demands of transit mixer applications specifically in mind. That application is actually called out as a proven fit for this motor, alongside other heavy-rotation equipment like road rollers and cranes. Cast iron holds up better than aluminum housings in environments where heat and repeated stress are constant factors, so it's a reasonable choice for a machine that runs hard most of the day.

Will this motor hold up on a transit mixer running multiple cycles a day?

Cast iron construction makes it durable enough for high-cycle, heavy-load environments like transit mixers.
