What Are The Main Spare Parts of Self Loading Concrete Mixer Truck

On infrastructure construction sites, self loader concrete mixer , with their integrated capabilities of "self-loading, mixing, and transporting," have become key equipment for improving construction efficiency. However, their stable operation depends on the coordinated operation of various components—particularly those that are prone to wear and require regular replacement, which directly impact equipment availability.

Core components of a self loading concrete mixer truck

1. Mixing system

Mixing drum: It is responsible for holding and mixing concrete. It's typically made of high-strength, wear-resistant steel (such as Q345B). Under normal use, it doesn't require replacement, but welds should be regularly inspected for cracks.

Mixing blades/liners (replaceable wear parts): These components directly rub against the concrete and wear out the fastest. Blades are typically designed as spirals, while liners are attached to the inner wall of the mixing drum. They are typically made of NM450 wear-resistant alloy and generally require replacement every 3-6 months (depending on the intensity of the application).

Hydraulic motor: It provides power for the mixer drum. If the speed drops or unusual noises occur, it's likely due to wear on the internal gears and requires complete replacement. Branded vehicles like Haomei Machinery are often equipped with imported motors from brands like Bosch and Sauer, resulting in a longer lifespan.

2. Loading system

Hopper: It holds aggregates such as sand, gravel, and cement. It is susceptible to deformation and cracking due to long-term impact. It is made of thick steel (6-8mm). Leakage or difficulty opening and closing requires prompt replacement to prevent impact on loading efficiency.

3. Power system

Engine: It provides the vehicle's power (including driving, mixing, and loading). Commonly used engines include Cummins and Yuchai. With normal maintenance, they can last up to 10 years. However, if serious faults such as cylinder scuffing or explosion occur, the original engine must be replaced.

Transmission: It connects the engine and drive axle, regulating vehicle speed and torque. If shifting jerks or shifting out of gear occurs, inspect the gears for wear and replace with genuine parts.

4. Hydraulic system

Hydraulic Pump: It provides hydraulic power for mixing, feeding, steering, and other actions. Gear pumps and plunger pumps are commonly used. If insufficient pressure occurs, it's likely due to internal wear and tear, requiring replacement with a genuine hydraulic pump.

Hydraulic Cylinder: In addition to the loading cylinder, hydraulic cylinders are also required for the mixer drum tilt and power steering. If the cylinder body or seals become stuck during extension or retraction, replace the cylinder body or seals. Original hydraulic cylinder seals are mostly made of imported materials and are less susceptible to leakage.

5. Travel System

OTR tires: It can bear the entire vehicle's weight (up to 20-30 tons fully loaded). Construction site conditions are complex (gravel, muddy), and they wear quickly. They generally need to be replaced every 6-12 months. Branded vehicles are often equipped with wear-resistant OTR tires such as Michelin and Chaoyang, with treads 30% thicker than standard tires.

Wheels: Deformation or cracks can cause tire deflation and deviation, requiring prompt replacement. Original wheels are made of high-strength aluminum alloy, are lightweight, and are impact-resistant.

6. Control and sensor system

Joystick: It controls actions such as loading, mixing, and unloading. Frequent operation can easily cause wear of the internal contacts, leading to control failure. Replace the original joystick (branded vehicle joysticks have a smoother feel and a lifespan of over 5 years). Welcome to inquire self loading concrete mixer price from us directly.
