What is the capacity of a concrete mixer truck?

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.

Why is a Clutch Installed in the Automotive Transmission System?

The reasons for installing a clutch in the automotive transmission system include ensuring smooth vehicle starting, facilitating gear shifting, and significantly reducing torsional vibration impacts from the engine. Specific reasons for installing a clutch: It enables smooth vehicle starting, allows for switching between different transmission gears to adapt to changing driving conditions, and prevents transmission system overload. It can significantly reduce torsional vibration impacts from the engine, extending the lifespan of transmission gears. Currently, the most widely used type in vehicles is the spring-loaded friction clutch (commonly referred to as the friction clutch). During driving, the driver can press or release the clutch pedal as needed to temporarily disconnect or gradually engage the engine with the transmission, thereby cutting off or transmitting the engine's power input to the transmission. Clutch Operation Essentials: The three key principles of clutch operation are: quick, slow, and linkage. When lifting the clutch pedal, the principle of "quick, slow, and linkage" should be followed. During starting, the action of pressing the clutch pedal should be swift and decisive, pressing it all the way down to ensure complete disengagement of the clutch. The phrase "quick, slow, and linkage" refers to the three stages of lifting the clutch pedal: initially lifting quickly, then slowing down when the clutch pressure plate begins to engage to the point of semi-linkage, and finally lifting the pedal slowly as it moves from semi-linkage to full engagement. While lifting the clutch pedal, the accelerator pedal should be gradually pressed down according to the engine's power output to ensure a smooth start. The accelerator operation should be steady and appropriate, and the throttle should only be increased when the clutch is fully engaged.
