What are the specifications of a concrete mixer truck?
2 Answers
Concrete mixer trucks come in various specifications and models, including 3 cubic meters, 3.5 cubic meters, 4 cubic meters, 5 cubic meters, 6 cubic meters, 8 cubic meters, 9 cubic meters, 10 cubic meters, 12 cubic meters, and 16 cubic meters. Each model differs primarily in terms of loading capacity. The volume of the mixer is a fundamental parameter; the larger the volume, the more concrete it can carry, and the higher the price of the mixer truck. Introduction to concrete mixer trucks: A concrete mixer truck is a specialized vehicle used to transport construction concrete. Due to its shape, it is often referred to as a 'snail truck.' Function of the mixer drum: These trucks are equipped with a cylindrical mixing drum to carry the mixed concrete. During transportation, the drum continuously rotates to ensure the concrete does not solidify.
I've been in the construction industry for twenty years, dealing with concrete mixer trucks all the time, and there's quite a variety of specifications. The capacity usually ranges from 3 to 12 cubic meters. The 6-cubic-meter trucks are compact and flexible, commonly used in urban construction sites as they don't easily get stuck on narrow roads, while the larger 12-cubic-meter trucks are suitable for long-distance transportation in suburban areas. The overall vehicle length is about 8 to 10 meters, with a width of around 2.5 meters to avoid width-restriction posts, and a height of approximately 3.8 meters to be cautious of bridge clearance limits. The empty weight is 11 tons, and when fully loaded, it can exceed 20 tons, relying on a three-axle setup for stability. The engine needs at least 350 horsepower to ensure the concrete doesn't solidify when climbing slopes, with a rotation speed of about 12 revolutions per minute to control and prevent splashing. When choosing, consider road conditions—smaller specifications are better for narrow alleys to avoid trouble. Here's a bit of experience-based advice: regular lubrication of the hydraulic system extends lifespan and keeps maintenance costs low. Prices vary significantly with specifications—larger capacities are more expensive but cost-effective in the long run.
