Safety Requirements:
Concrete mixer trucks must comply with GB 7258, "Technical specifications for safety of power-driven vehicles operating on roads," covering safety standards for components such as braking systems, lighting signals, and tires.
The design and manufacture of the mixing drum must ensure no leakage or overturning occurs during transport; strict regulations also apply to the drum's rotation speed and tilt angle.
Environmental Requirements:
Emissions must meet the National VI (China VI) standard, with engine pollutant emission limits strictly adhered to.
Vehicle noise control must comply with GB 1495, "Limits and measurement methods for exterior noise from motor vehicles during acceleration."
Performance Parameters:
Mixing drum volume and rotation speed are key parameters; typically, rotation speed is controlled between 1 and 18 revolutions per minute, with specific values varying based on the vehicle model and intended use.
Performance parameters such as gradeability, turning radius, and ground clearance must also meet national standards to ensure stability and safety across various road conditions.
Ancillary Equipment:
Concrete mixer trucks must be equipped with components such as water tanks, hydraulic systems, and pumps; the performance and safety of this equipment must also comply with relevant standards.
