What routine maintenance should a CTI verify on a ready-mix truck before delivery?

• A. Wheel alignment and brake pads
• B. Drum integrity, seals, bearings, hydraulic gates, and calibration of the water system and cleanliness
• C. Radio and air conditioning
• D. Mirror alignment

Answer: (B)

Before delivery, a CTI focuses on items that directly affect the quality and reliability of the concrete being delivered. The routine maintenance to verify includes the drum’s condition—checking for cracks or signs of wear that could cause leaks or improper mixing—along with seals and bearings to ensure the drum rotates smoothly without leakage or failure. The hydraulic gates must operate correctly to control the discharge and any water addition, and the water system itself should be calibrated to deliver the right amount of water for the mix. Cleanliness is also checked to prevent hardened residue from contaminating the next load and to avoid drainage or discharge problems. These checks matter because they ensure the mixer can deliver uniform, properly behaved concrete and that the washout and discharge systems work as intended. While other items like wheel alignment, brakes, radio, or mirror alignment are important for safety and operator comfort, they do not directly impact the immediate quality and performance of the concrete being delivered.
