The vulnerable parts of self loading concrete mixer trucks mainly include the following categories.

Hydraulic system components:

Hydraulic pump: Long term high-pressure operation may cause wear or damage.

Hydraulic motor: also susceptible to long-term high-pressure and high-speed operation.

Hydraulic cylinder: worn out due to frequent expansion and contraction.

Hydraulic valve: a key component that controls the hydraulic system and is susceptible to contamination and wear.

Mixing device components:

Mixing blade: In direct contact with concrete, it may deform or break after long-term wear.

Mixing shaft: It bears the rotational force of the mixing blades and is prone to wear or breakage.

Bearings: support the mixing shaft, long-term operation may cause wear or damage.

Tire and suspension system components:

Tires: Wear and tear caused by long-term driving and load-bearing.

Shock absorber: worn out due to long-term vibration.

Steel plate: a critical component in suspension systems that is prone to wear or deformation.

Lubrication system components:

Lubricating oil pump: a component that provides lubricating oil, long-term operation may cause wear and tear.

Lubricating oil filter: filters impurities in lubricating oil to protect the lubrication system.

Electrical system components:

Cable: Damaged due to aging or improper use.

Wires: susceptible to environmental corrosion and wear.

Controller: A critical component that controls the operation of a mixer truck and may be damaged due to aging or improper use.

Sealing element:

Oil seal: a key component that prevents lubricating oil leakage.

Gas seal: Ensure the normal operation of the pneumatic system.

Other vulnerable parts:

Host belt: It is prone to wear and breakage due to prolonged operation or tension.

Rolling support and conveyor belt: They are prone to wear due to material impact and friction.

Pneumatic components such as solenoid valves and cylinders are prone to malfunction after prolonged operation.

In order to extend the service life of the self loading mixer truck and ensure safe operation, these vulnerable parts should be inspected and maintained regularly, and replaced in a timely manner according to the actual situation.

At the same time, pay attention to driving style and avoid long-term overloading or overloading to reduce damage to the vehicle.
