The pumping system of a concrete pump truck consists of several spare parts that work together to transport concrete from the hopper to the boom. In this article, we will provide a detailed overview of the various spare parts inside the hopper of a concrete pump truck.
Concrete S-Valve
The S-Valve is a key spare part of a concrete pump, and it controls the flow of concrete from the hopper to the boom. The S-Valve is designed to be durable and withstand the abrasive nature of concrete pumps.

Concrete Delivery Cylinder

The delivery cylinder is a critical spare part of the pumping system, and it is responsible for pushing the concrete out of the hopper and into the boom. The delivery cylinder is typically made of hardened steel and is designed to withstand the high pressures and abrasive materials present in the concrete.
Concrete Piston
The piston is a spare part of the delivery cylinder that is responsible for pushing the concrete out of the hopper and into the boom. The concrete piston is typically made of high-strength material, such as rubber or polyurethane, and is designed to be durable and long-lasting.

Concrete Plunger Cylinder

The plunger cylinder is a hydraulic cylinder that is responsible for moving the boom from side to side. The plunger cylinder is typically mounted on the hopper and is designed to be durable and reliable.
Concrete Swing Lever
The swing lever is a spare part of the plunger cylinder that controls the movement of the boom. The swing lever is typically operated by a hydraulic system and is designed to be precise and responsive.

Concrete Cutting Ring

The cutting ring is a spare part of the hopper that is designed to cut off any excess concrete as it is pushed out of the hopper and into the boom. The cutting ring is typically made of high-strength material, such as hardened steel, and is designed to be durable and long-lasting.
Concrete Wear Plate
The wear plate is a spare part of the hopper that is designed to protect the hopper from the abrasive materials in the concrete. The wear plate is typically made of high-strength material, such as hardened steel, and is designed to be durable and long-lasting.

Concrete Mixing Shaft

The mixing shaft is a spare part of the hopper that is responsible for mixing the concrete inside the hopper. The mixing shaft is typically powered by a motor and is designed to be durable and reliable.
Concrete Agitator Motor
The agitator motor is a spare part of the hopper that powers the mixing shaft. The agitator motor is typically powered by electricity or hydraulic power and is designed to be durable and reliable.

Concrete Bearing Flange

The bearing flange is a spare part of the hopper that connects the mixing shaft to the motor. The bearing flange is typically made of high-strength material, such as steel, and is designed to be durable and long-lasting.
Conclusion
The spare parts inside the hopper of a concrete pump truck work together to transport concrete from the hopper to the boom. Understanding the role of each spare part is critical to maintaining the safety and efficiency of the pumping system. Regular maintenance and replacement of worn parts are essential to ensure that the system operates safely and efficiently on the job site.
