As a key transportation equipment in construction, the safe driving and proper maintenance of concrete mixer trucks are of vital importance for ensuring the construction progress, extending the service life of the vehicles and guaranteeing the safety of personnel. The following is a detailed introduction to the safe driving skills and daily maintenance points of concrete mixer trucks for you.

I. Safe Driving Skills for Concrete Mixer Trucks
(1) Preparations before departure
1. Comprehensive vehicle inspection: Walk around the vehicle to check if there is any damage to the body, whether the tire pressure and screws are normal, and especially inspect the connection parts of the mixing tank. Meanwhile, check the brake fluid level of the braking system and the wear condition of the brake pads to ensure good braking. Check the lighting system to ensure that the headlights, turn signals and brake lights are functioning properly.
2. Be familiar with the transportation route: Plan the route in advance, understand whether there are any construction sections, curves, steep slopes, etc., and avoid congested sections. You can use map software or consult a local driver to keep track of the road conditions.
3. Adjust the driving posture: Adjust the seat so that both feet can easily operate the clutch, brake and accelerator, and when holding the steering wheel with both hands, the arms should naturally bend and be able to flexibly operate the components. Adjust the rearview mirror to reduce blind spots.
(2) Operation while in motion
1. Control vehicle speed and distance: The mixer truck is heavy and the concrete is in a dynamic state. On ordinary roads, the speed should be maintained at 40 to 60 kilometers per hour. Slow down in advance at curves and intersections. Keep a distance of at least twice that of an ordinary vehicle from the vehicle in front to prevent rear-end collisions.
2. Smooth turns and U-turns: Before turning, turn on the turn signal and slowly turn the steering wheel to avoid sudden steering that may cause the vehicle to overturn. When making a U-turn, choose a spacious area and use reversing if necessary.
3. Avoid sudden braking and acceleration: Sudden braking and acceleration can cause the concrete inside the tank to shake, damage the tank structure and affect the stability of driving. One should predict the road conditions in advance and accelerate and decelerate smoothly.
(3) Responding to special circumstances
1. Driving in bad weather: Reduce speed in rainy days, turn on fog lights and low beam headlights, and avoid areas with deep water. Install anti-skid chains on snowy or icy roads, drive slowly and increase the distance between vehicles.
2. Driving within the construction site: Slow down when entering the construction site, drive along the designated route, and give way to the construction area and other vehicles. When turning or reversing, pay close attention to the surrounding situation. If necessary, have a dedicated person to direct.
3. Handling of sudden malfunctions: In case of vehicle malfunction, move to a safe area, turn on the hazard warning lights, and place warning signs. Make a preliminary judgment on the fault. If it cannot be solved, call the rescue number.
II. Key Points for Daily Maintenance of Concrete Mixer Trucks
(1) Vehicle body and chassis maintenance
1. Clean the vehicle body: After transportation, promptly clean the vehicle body with a high-pressure water gun and special car wash liquid to remove dirt such as concrete and soil, preventing corrosion of the vehicle body’s paint surface and structure.
2. Inspect the chassis components: Regularly check the suspension, transmission and steering system components, such as springs, shock absorbers, transmission chains and steering tie rod ball joints. Repair or replace any problems found in a timely manner.
3. Lubricate chassis components: Regularly lubricate lubrication points such as the universal joint of the drive shaft, the steering joint, and the brake caliper to reduce component friction.
(2) Maintenance of the mixing tank
1. Clean the mixing tank: At the end of each day’s work, add clean water to start the mixing device for flushing, and then use a high-pressure water gun to rinse thoroughly to prevent the concrete from remaining and hardening.
2. Inspect the stirring blades: Regularly check the wear of the blades. Replace them in time when the wear exceeds one-third of the original thickness. At the same time, tighten the connection between the blades and the tank body.
3. Maintain the transmission system of the mixing tank: Regularly check the oil level and quality of the reducer, and inspect the coupling bolts and hydraulic pump for any oil leakage to ensure the normal operation of the transmission system.
(3) Engine Maintenance
1.Change the engine oil and oil filter: According to the engine manual, change the engine oil and filter every 5,000 to 10,000 kilometers to ensure the engine operates well.
2. Check the air filter: Regularly inspect the filter element. Clean or replace it in time when it is dirty. In a dusty environment, increase the replacement frequency appropriately.
3. Maintain the cooling system: Regularly check the coolant level, inspect the pipelines for any leaks, and clean the radiator of the water tank to ensure good heat dissipation.
The safe driving and daily maintenance of concrete mixer trucks require drivers to have a high sense of responsibility and professional knowledge. Strictly adhering to safety driving regulations and doing a good job in daily maintenance can effectively enhance the safety and reliability of vehicles, providing a strong guarantee for the smooth progress of construction projects.
