  • Why The Structural Malfunction Of The Drum Rollers Happens Frequently?

    Why The Structural Malfunction Of The Drum Rollers Happens Frequently?


    1. Operation under overload. After calculating, a full loaded 12m3 mixer truck’s back supports are bearing the force of 1.32x105N, which means the each drum roller is bearing the force of 7.6x104N. If the truck starts working suddenly, the mixer drum will force the drum roller more than 7.6x104N at that moment. So the drum rollers are working under the overloading condition frequently. 2. Influenc...
