What is the capacity of a concrete mixer truck?
1 Answers
Concrete mixer trucks commonly have a capacity of 8 cubic meters, with the exact size depending on the vehicle model. Working principle of concrete mixer trucks: Domestic concrete mixer trucks adopt the power take-off method from the main vehicle engine. The power take-off device functions by extracting engine power through the operation of the power take-off switch, which then drives the mixing drum via the hydraulic system. The mixing drum rotates forward during the loading and transportation processes to facilitate material intake and concrete mixing, and reverses during discharge. The power connection with the engine is severed upon completion of work. The mixing device mainly consists of the mixing drum and its auxiliary support components. The mixing drum serves as the container for concrete loading; during rotation, the concrete moves along the spiral direction of the blades, undergoing mixing and stirring through continuous lifting and turning. During loading and transportation, the mixing drum rotates forward, causing the concrete to move inward along the blades, while during discharge, it rotates backward, allowing the concrete to be discharged outward along the blades. Maintenance of concrete mixer trucks: As vehicles for transportation, concrete mixer trucks must adhere to the maintenance and repair regulations stipulated in the Ministry of Transport's Order No. 13 of 1990, implementing a system of "regular inspection, mandatory maintenance, and condition-based repair." Under this overarching principle, maintenance and repair should be conducted in conjunction with the actual conditions of the concrete mixer trucks. For daily maintenance, in addition to the routine maintenance of the vehicle's engine, chassis, and other parts, the following maintenance tasks must be performed.
