Choosing a concrete lifting pump looks complicated, but it comes down to three practical questions. A pump that cannot handle your stone size or your height will struggle on site and slow your crew. This guide walks you through each question, shows how the YG-20 to YG-60 models fit different jobs, and lists the accessories you need before the first pour.

Question 1: What Stone Size Will Your Trailer-Mounted Concrete Pump?

Start with the aggregate. Stone size sets the pipe diameter, and pipe diameter helps decide the model. Many floor projects use fine stone concrete, where the stones stay under 2 cm. Standard fine stone measures 5 mm to 1 cm.

Smaller models below the YG-40 usually run 80 mm pipe. The YG-40 can pump larger stones and needs 100 mm or 125 mm pipe, depending on stone size. Use this table as a guide:

Stone Size	Typical Pipe Diameter	Suitable Models
Fine stone, up to 2 cm	80 mm	YG-20, YG-30, YG-40, YG-50, YG-60
Under 3 cm	100 mm	YG-30, YG-40, YG-50, YG-60
Under 4 cm	125 mm	YG-40, YG-50, YG-60
Up to 5 cm	125 mm	YG-60

Question 2: How High and How Far Must the Concrete Travel?

Next, measure the vertical height and the horizontal distance. This is where a concrete lifting pump proves its value. If your height stays within 30 m, you do not need a large machine. A YG-20 or YG-30 handles that range.

Model	Vertical Distance	Horizontal Distance	Working Pressure
YG-20	40-50 m	80-100 m	15 MPa
YG-30	20-60 m	50-150 m	20 MPa
YG-40	30-130 m	50-350 m	23 MPa
YG-50	30-150 m	50-500 m	23 MPa
YG-60	30-150 m	50-500 m	23 MPa

However, keep your pipe layout in mind. A longer pipe run always includes bends, because the line must turn when it climbs or runs flat. Therefore, plan your layout before you choose the model.

Question 3: How Much Output Do You Need?

Finally, decide how many cubic meters per hour you need. The YG-20 delivers 8-12 m³/h, and the YG-30 delivers 13-15 m³/h. The YG-40 reaches 20-25 m³/h, the YG-50 reaches 30-35 m³/h, and the YG-60 reaches 55-60 m³/h.

Compare these numbers with your daily pour plan. Then check that the same model also fits your stone size and distance. These three answers work together, so one answer alone never picks the model.

Choose Electric or Diesel Power Line Pump for Sale?

Electric versions use a 22 kW motor on the YG-20, 37 kW on the YG-30, 45 kW on the YG-40, 55 kW on the YG-50 and 90 kW on the YG-60. The diesel engine models listed for the YG-20 to YG-50 range are 4102, 4105, 4108 and 6102. For diesel power on the YG-60, contact our team.

Choose electric when your site has a stable power supply that can run the motor. Choose diesel when it does not.

Common Mistakes to Avoid

• Skipping the stone size check. A pipe that does not match your stone size causes trouble from the first pour.
• Looking at output only. Height and distance matter just as much.
• Ordering too much hose. Hose cannot handle pressure like steel pipe.
• Forgetting the power supply. Confirm your site power before you choose an electric model.

Conclusion

Selecting a concrete lifting pump comes down to three answers: stone size, height and distance, and output. Match them to the YG-20 to YG-60 table, plan your pipes and elbows, and choose electric or diesel power based on your site. If you need a cement concrete pump for a floor, bridge, or tunnel project, send us your stone size, height, horizontal distance and output target. We will recommend the right model.
