Purchasing a used concrete pump truck from overseas is a significant investment. While Chinese brands like SANY and Zoomlion offer incredible value and durability, the condition of a used machine depends entirely on its previous maintenance.
To help contractors avoid costly mistakes, our engineering team at Shirun Heavy Machinery has compiled the ultimate inspection checklist based on our 12 years of hands-on experience:
1. Inspect the Boom Structure for Micro-Cracks
The boom is the most critical safety component. Do not just look at the fresh paint. You need to inspect the stress points and weld seams on the 1st and 2nd boom sections. Any signs of re-welding without professional reinforcement are a red flag.
2. Check the Hydraulic System Pressure
A pump truck is useless if it lacks pumping power. Listen to the main hydraulic pump during operation. An abnormal whining noise usually indicates internal wear. Always ask your supplier for a real-time pressure testing video before making a decision.
3. Evaluate the Wear Parts (Glasses Plate & Cutting Ring)
These are consumables, but their condition tells a story about the machine. At Shirun Heavy Machinery, we make it a standard procedure to replace heavily worn delivery pipes, glasses plates, and cutting rings with brand-new ones before shipping, saving our clients immediate replacement costs.
4. Verify the Chassis and Engine Health
Whether it’s a Mercedes-Benz, Isuzu, or Volvo chassis, check for chassis rust and engine blow-by. A machine that worked in a coastal city might have severe undercarriage corrosion.
Conclusion
Don’t gamble with your project’s timeline. At Shirun Heavy Machinery, every used pump truck in our yard has already passed this rigorous checklist. Contact us today to get a detailed inspection report and testing video for your next machine.
