The comprehensive catalog of mixer truck parts refers to the collection of various components and accessories required for concrete mixer trucks, covering all aspects from the power system to the drum structure. These parts primarily include the following categories:
Power System Components: Such as engines (brands like Weichai, Yuchai, etc.), transmissions, drive shafts, clutch assemblies, etc., which directly impact the vehicle's power output and fuel efficiency.
Hydraulic System Components: Includes hydraulic pumps, hydraulic motors, hydraulic hoses, control valves, etc., used to drive the mixing drum rotation. Regular inspection of seals and pressure values is required (typical operating pressure: 16-20MPa).
Mixing Drum Structural Components: Such as mixing blades (typically made of wear-resistant alloy steel with a thickness ≥8mm), feed hoppers, discharge chutes, drum support rollers, etc., which directly affect concrete mixing quality and discharge efficiency.
Chassis Components: Involve tires (e.g., 11.00R20 steel-belted tires), leaf springs, braking systems (air or hydraulic brakes), axles, etc. Select appropriate models based on load capacity (for 8-cubic-meter trucks, single-tire load ≤3 tons is recommended).
Electrical Components
Includes lighting systems, sensors (e.g., RPM sensors, pressure sensors), and control panels for monitoring operational status.
Auxiliary Components
Such as water pumps (for drum cleaning, recommended flow rate ≥60L/min), guardrails, toolboxes, etc.
Application Scenarios
Component selection must match mixer truck specifications (e.g., 8-cubic-meter trucks require chassis with 3400+1350 wheelbase) and operating environments (reinforced braking systems required for mountainous terrain).
Precautions
Hydraulic oil should be replaced every 500 hours, using ISO VG46 viscosity grade;
Mixing blades must be replaced when wear exceeds 30% of original thickness to prevent concrete segregation;
Regularly calibrate RPM sensors to ensure drum rotation speed is controlled at 1-3 rpm (during loading) or 8-12 rpm (during mixing).
