Driving a self loading mobile concrete mixer is a task that requires a high level of concentration and skill, as these vehicles have important safety and stability requirements when transporting concrete. There are some tips:
1. Familiarize yourself with the vehicle: Before driving the self loading concrete mixer truck, make sure you are familiar with all the vehicle's controls and instruments and have a clear understanding of the vehicle's size, weight, and any potential mechanical issues.
2. Driver Training: Receive specialized training on how to properly operate and drive this type of vehicle. Be familiar with the driving characteristics and handling techniques of the vehicle.
3. Load limit: Strictly comply with the maximum load limit of the self loading mixer truck. Overloading reduces vehicle stability and increases the risk of accidents.
4. Vehicle inspection: Before each trip, all systems of the mixer truck must be carefully checked, including brakes, tires, suspension, mixing barrels, etc., to ensure that all equipment is working properly.
Engine maintenance
It is inseparable from engine oil. The engine oil of self-loading mixers is a consumable. For mixer trucks that are often used on construction sites, the maintenance of engine oil is even more important. So what methods can be used to extend the oil cycle of self-loading mixer trucks?
1. Prevent fuel from leaking into the oil pan, because the fuel pan will dilute the engine oil, thereby greatly reducing the viscosity of the engine oil and losing the lubrication effect prematurely. Therefore, diesel engines require sufficient fuel supply pressure from the fuel injection pump, good atomization of the injector, and reasonable throttle control to ensure complete fuel combustion.
2. Avoid operating the engine in a high-temperature environment. The engine generally requires a normal operating temperature of 80°C to 95°C. If the temperature is too high, the engine oil will become thinner and the engine oil will deteriorate faster. Once the temperature is found to be too high, it must be stopped for inspection, and normal work can continue until the fault is eliminated.
HOW TO CLEAN THE VEHICLE AFTER USING
After use, it is very important to clean the self loading transit mixer promptly and thoroughly to ensure that no concrete residue accumulates or is clogged inside the mixing drum, while maintaining the operating efficiency of the vehicle and the quality of the concrete. The following are general cleaning steps:
Drive away from the construction site: Before starting cleaning, drive the mixer truck away from the construction site to ensure that no new concrete is poured into the mixing drum.
Dumping Concrete Residues: At a cleaning station or designated dumping area, completely dump the mixer drum to remove all concrete residue.
Inject clean water: Inject an appropriate amount of clean water into the mixing drum, then start the mixing drum and let the clean water rotate in the mixing drum to clean the drum wall and mixing blades.
High-pressure flushing: If conditions permit, you can use a high-pressure water gun to flush the mixing drum to more thoroughly remove residual concrete and dirt.
Repeated cleaning: If there are still stubborn concrete residues in the mixing drum, you can clean it multiple times until the inside is clean and free of residue.
Clean the exterior: In addition to the inside of the mixing drum, you also need to clean the exterior of the vehicle, including the body and tires. Cleaning the exterior helps prevent concrete from hardening and vehicle corrosion.
Inspection and maintenance: During the cleaning process, check the hydraulic system, rotating device and other key components of the mixer truck for abnormalities or damage. If problems are found, repair them in time.
Storage and maintenance: After cleaning, the self propelled concrete mixer truck should be stored in a dry, well-ventilated place. Carry out regular maintenance and upkeep on the mixer truck to ensure long-term reliable operation of the vehicle.
At the construction site, there should be a designated cleaning area to avoid direct discharge of sewage into the environment. In addition, relevant safety operating procedures must also be followed to ensure that no harm is caused to operators during the cleaning process.
