Let the concrete mixer truck manufacturer share some precautions for the construction of concrete mixing and transport trucks.

　　Concrete Mixer Truck Manufacturer: Precautions for Use During Concrete Mixer Truck Construction

　　In fact, concrete mixer trucks should pay closer attention to certain precautions during operation; otherwise, they are very likely to encounter various malfunctions, which can hinder construction progress, affect the overall project schedule, and even pose risks to operators and equipment. Below, the editor from the mixer truck manufacturer will share with you some important precautions for using concrete mixer trucks in construction.

　　1. Concrete mixer trucks have a high center of gravity, making them prone to accidents when driven at high speeds. Before turning, slow down and downshift in advance. While turning, try not to step on the brake pedal. Keep an eye on whether the mixing drum is still rotating at all times, and slow down as much as possible. If the speed is too high, the vehicle may sway or even roll over.

　　2. The mixer truck needs to stop the rotation of the drum when driving on road sections with steep inclines. When the vehicle is fully loaded, as it approaches such a section, the rotation of the drum should be halted to ensure smoother vehicle operation.

　　When the road surface is uneven, navigate potholes at an appropriate low gear to ensure the vehicle maintains consistent acceleration at all times. Be mindful to avoid obstacles, start off smoothly, and refrain from shifting gears randomly or downshifting prematurely—instead, downshift in advance to keep the vehicle fully powered.

　　3. Before long-distance driving or descending a slope, make it a habit to test your brakes. Never let a concrete mixer truck coast downhill in neutral. Use lower gears to slow down the engine. On downhill roads with curves, reduce speed well in advance before turning; then downshift and further decelerate. Using the engine brake while in gear provides better braking performance.

　　4. Plan your route carefully in advance, paying attention to height restrictions. The construction site has complex road conditions—be cautious of trees and take care not to scratch the cables.

　　Next, let’s talk about the safe operation of concrete mixer trucks at the mixer truck manufacturing plant.

　　Safe operation is the fundamental guarantee for concrete mixer trucks to complete their work tasks, and it also provides reliable protection for the safe operation and maintenance of these trucks as well as the personal safety of construction workers in the surrounding area.

　　1. Check

　　Check whether there is any debris accumulation inside the vehicle body, and inspect the levels and leakage conditions of diesel fuel, engine oil, various gear oils, various power steering fluids, engine coolant, and brake fluid.

　　2. Transportation

　　During transportation, concrete mixer trucks should maintain a slow speed of 3 to 6 revolutions per minute. Under normal mixing and driving conditions, the maximum speed should not exceed 50 kilometers per hour. When turning, avoid making sharp turns and keep the turning speed below 15 km/h; otherwise, there is a risk of rollover. The empty truck’s speed should not exceed 60 km/h. If the slump loss is excessive, water may be added in appropriate amounts, provided that the concrete’s design mix proportions are still met. This task must be carried out by laboratory technicians. Furthermore, adding water directly into the mixing drum is strictly prohibited.

　　3. Uninstall

　　After the concrete is delivered to the construction site, the site supervisor should unload the material in sequence, ensuring a clean and thorough unloading to avoid waste. The mixing truck’s drum must be cleaned promptly to remove any accumulated water.

　　Drivers should perform regular maintenance on concrete mixer trucks to ensure their service life and proper operation. The roller nozzles should be lubricated with high-pressure grease once a week, and each shift should involve applying a small amount of grease containing graphite or molybdenum disulfide to the raceways. The drive shaft of the oil pump should be lubricated once a week.

　　Alright, that’s all for today’s episode on the concrete mixer truck manufacturer. Thanks for watching, and we’ll see you in the next episode.
