  • Publication number: 20220072736
    Abstract: A concrete mixer vehicle includes a chassis, a cab coupled to the chassis, a drum assembly coupled to the chassis, and a module coupled to the chassis and positioned rearward of the drum assembly. The module includes a prime mover, a cooling system, and a hood. The hood has a first end positioned proximate the drum assembly, an opposing second end positioned proximate a rear end of the chassis, and a top surface. The hood defines an internal cavity within which the prime mover and the cooling system are disposed. The first end defines an inlet airflow cavity. The inlet airflow cavity has a bottom surface and an air inlet positioned between the top surface and the bottom surface. The air inlet connects the inlet airflow cavity to the internal cavity.
