The service life of a concrete pump is a significant concern for many construction companies. To extend its lifespan, regular maintenance is essential. While many people know that daily maintenance is important, they may not be clear on how to perform specific inspections or maintenance tasks.
Concrete pump inspections are typically based on different components, with the frequency of inspections varying depending on the likelihood of wear or damage. Components that are more prone to wear require more frequent inspections, while fixed parts can be checked less often. Below is a guide to the inspection schedule of the main components of a concrete pump:
1. Daily Inspection
Daily checks should focus on visible wear and deformation, loose exposed parts, operational changes, and performance issues. Specific tasks include:
- Checking for oil leaks.
- Inspecting hoses for damage.
- Ensuring all lubrication points have adequate grease.
- Looking for any safety risks in the driving system.
2. Monthly Inspection
After pumping approximately 2,000 cubic meters of concrete or every month, the following components should be checked:
- Damage to the sliding valve.
- Wear on the delivery pipes.
- Hydraulic oil levels.
- Lubrication of forced lubrication points.
- Routine maintenance on the truck’s components.
3. Semi-Annual Inspection
After pumping approximately 12,000 cubic meters of concrete or every six months, the following should be inspected:
- Damage to the lower case of the sliding valve and delivery cylinder.
- Electrical components.
- Deterioration of hydraulic oil.
- Damage to the boom structure.
- Routine repairs and maintenance on the truck.
4. Annual Inspection
After pumping approximately 24,000 cubic meters of concrete or annually, perform a more thorough inspection, including:
- Checking the mixer, mixing oil motor, and rotary oil motor.
- Inspecting the water pump and all hydraulic pumps.
- Replacing the hydraulic oil.
Regular inspections and maintenance are crucial to ensuring the reliability and longevity of a concrete pump. Following these schedules can help prevent breakdowns and extend the machine’s operational life.
