Industrial-grade Concrete Mixer Truck Preparation Method
Industrial concrete mixer trucks (also known as concrete mixing and delivery trucks) are highly integrated specialized vehicles, and their preparation process includes the following key steps:
Chassis Modification
Use a heavy-duty truck chassis and add a subframe to support the mixing drum.
Equip a power take-off (PTO) unit to obtain engine power for driving the hydraulic system.
Mixing Drum Fabrication
The drum is usually rolled from seamless steel pipe, with spiral blades welded inside (pitch about 30–40 cm, angle 30°–45°).
Segmented prefabrication process: the front cone, rear cone, and cylinder are formed separately and then welded together to ensure structural accuracy.
Hydraulic Transmission System Integration
Engine power → Power Take-Off → Hydraulic Pump → Hydraulic Motor → Reducer → Mixing Drum Rotation.
Mixing drum speed control: 6–10 rpm when loading, 1–3 rpm during transport, 3–14 rpm when discharging.
Auxiliary System Installation
Loading/unloading mechanisms (hopper, guide pipe, movable discharge chute).
Cleaning system (air or water pressure to rinse the drum).
Electrical and control systems for controlling speed and steering.
Testing and Acceptance
Including driving stability, mixing uniformity (slump test), braking performance, etc.
