Unstoppable in Downpours: Sany Electric Concrete Mixer Trucks Ensure Mission Del
June 25,2026
Recently, widespread continuous heavy rain has led to frequent waterlogging on roads and low-lying factory areas, posing a huge test for electrified equipment: once the electric system gets wet and short-circuits, it can lead to work stoppages and order losses at best, and significant safety hazards at worst! It is understood that customers using Sany electric concrete mixer trucks have been operating normally during the flood season. So, what are the hardcore waterproof technologies and practical features that Sany electric concrete mixer trucks rely on to operate stably without fear of heavy rain and waterlogging?
Safety is No Small Matter, Waterproofing Shows True Quality
Sany electric concrete mixer trucks can operate stably in heavy rain, waterlogging, and waterlogged factory areas. Waterproofing is achieved through a five-layer system that includes a positive vehicle architecture + high protection for electric hardware + sealed pipelines + rigorous vehicle testing + physical isolation protection. The core electric protection reaches the industry's top IP68 standard and is known as the "diving mixer truck".
Full Chassis Waterproof Architecture, Calmly Facing Waterlogged Roads
Pipeline Six-Prevention Sealing: High and low-pressure, and air pipelines are arranged in partitions, following the "waterproof, dustproof, shockproof, wear-resistant, tear-resistant, interference-resistant" standards. Connectors use injection molding processes and double-corrugated tube structures to prevent water ingress and short-circuiting.
Triple Factory Water Crossing Verification: Each vehicle must pass a 360° high-pressure spray, 10MPa water gun impact, and 1-meter deep water immersion test, covering daily heavy rain and shallow water scenarios.
Cab Waterproof Design: Double sealing strips on doors and dashboards + damping water partition boards to prevent rainwater leakage and ensure the stability of the electric control screen.
Electric System IP68 Protection, Building a Safe Bottom Line
Top-Level Protection Grade: The battery pack, drive motor, and vehicle control system all uniformly reach the IP68 standard, capable of being submerged in 1 meter of water for a long time, far exceeding the common industry IP67 protection.
Multi-layer Sealing Structure: The battery pack uses a thickened aluminum alloy one-piece shell + high-temperature resistant sealing glue, with independent water layers for the battery cell modules, and fully sealed water-cooled pipelines to block water vapor intrusion.
Intelligent Monitoring and Early Warning: The self-developed BMS system monitors the humidity of the battery pack in real-time, automatically issues early warnings and limits power output when water ingress occurs, with warning information synchronized to the driver's TruckLink terminal.
Special Cells and Thermal Management: Low internal resistance lithium iron phosphate cells + full thermal management to suppress condensation in humid environments and reduce battery decay.
Maintenance Has a Method, No Panic During Flood Season
Pre-trip Inspection
1. Avoid low-lying waterlogged sections during heavy rain warnings, do not force passage through water deeper than half the tire;
2. Check that the chassis guard plate and battery pack shell are undamaged, and the wiring harness sealing rings are not falling off or aging;
3. Clean the cab drainage slots and check the door and window sealing strips.
Water Crossing and Washing Standards
1. Cross water at a low and even speed, do not stop, shift gears, or abruptly press the accelerator during the process;
2. When washing the vehicle, avoid the battery box, electric control plugs, and high-voltage wiring with high-pressure water guns;
3. After being deeply soaked in water, immediately cut off the high-voltage power, do not start, and contact the service station for inspection.
Post-Rain Maintenance Points
1. Rinse the chassis and battery pack of mud and sand, empty the drainage holes of water, and spray insulating waterproofing agents on electrical plugs;
2. Dry the brake
