• Metal Base: Serves as the installation and load-bearing base, ensuring the stability of the components.
• Dual Control Levers: Linked to the base through a spherical joint, allowing flexible angle adjustment during operation.
• Black Spherical Grip: Designed for easy grip by the driver to achieve precise control.
• Rod with Red Components: Connects to the vehicle's hydraulic system, converting manual operations into hydraulic signals to drive the mixing drum.

The control system of the concrete mixer truck operates by manually manipulating the dual levers. Through the hydraulic transmission system, power is transmitted to the mixing drum, precisely controlling its speed and rotation direction. This ensures continuous mixing of concrete during transportation to prevent segregation and meets the discharge requirements when unloading.

This control system is the core support for the "mixing+transportation" function of the concrete mixer truck. It is widely used in construction sites and municipal projects. By precisely controlling the mixing drum, it ensures the quality and transportation efficiency of concrete, making it a key element for the efficient operation of the mixer truck.
