As the summer heat persists, concrete mixers face greater operational challenges during transport operations. High temperatures not only increase the likelihood of malfunctions in the engine, radiator, and tires but also affect the quality of concrete transport and vehicle operational efficiency. To ensure stable equipment operation during the summer, it is particularly important to strengthen daily inspections and implement proper maintenance.
Enhanced Management of the Engine and Cooling
System in High-Temperature Environments
As the core power system of a concrete mixer
truck, the engine is more prone to overheating during prolonged, high-load
operation in the summer. While driving, the operator should closely monitor
changes in coolant temperature. If the temperature becomes excessively high,
the vehicle should be parked in a shaded area immediately, the engine should be
kept idling, and the hood should be opened to aid in heat dissipation.
At the same time, the cooling
system—including key components such as the radiator, water pump, fan, and
thermostat—should be inspected regularly. Coolant should be replenished
promptly to ensure the cooling system remains in good working condition.
Battery and Tire Checks Are Essential
High summer temperatures accelerate the
evaporation of water inside the battery, making it prone to low fluid levels.
Therefore, it is necessary to regularly check the electrolyte level and
promptly top up with distilled water to prevent issues with vehicle starting
and electrical system stability.
Tires are also susceptible to overheating in
high-temperature environments due to abnormal tire pressure. During daily use,
tire pressure should be checked regularly, and prolonged continuous driving
should be avoided. Before driving through water, it is also necessary to allow
the tires to cool down appropriately to reduce the risk of tire damage.
Properly Manage Concrete Transport Conditions
During summer construction, to minimize
issues such as premature setting during concrete transport, use admixtures such
as water-reducing agents, retarders, or fly ash as needed to help control the
concrete’s consistency and improve transport stability. For long-distance
transport, it is even more critical to carefully control the proportion of
admixtures used to ensure construction quality.
Regularly Clean the Mixer Drum to Improve
Equipment Stability
Drum cleaning is a critical part of summer
maintenance. Before each loading, the inlet should be flushed to keep the
interior moist; after unloading, the outlet and the interior of the drum should
be cleaned promptly to prevent hardened concrete residue. After work is
completed, the mixer drum and surrounding areas must be thoroughly cleaned to
minimize the impact of cement clumping on the equipment.
Additionally, during hot weather, inspections
and maintenance of components such as air filters, intake lines, engine oil,
and oil filters should be intensified to promptly identify abnormalities and
reduce equipment failure rates.
As the intensity of summer construction
continues to increase, high-temperature maintenance management for concrete
mixer trucks is becoming a critical factor in ensuring transportation
efficiency. By strengthening daily inspections and implementing scientific
maintenance, equipment stability and construction continuity can be effectively
enhanced, providing more reliable transportation support for construction
projects.
