Common Issues with Vemco Equipment
Even with the robust design of Vemco machines, operators can encounter a range of mechanical, electrical, and operational issues. Below are some common problems and their possible causes.
1. Hydraulic System Failures
Symptoms: Slow or unresponsive movement, strange noises, or oil leakage around hydraulic components.
Possible Causes:

• Low hydraulic fluid levels.
  
• Contaminated hydraulic fluid.
  
• Worn-out hydraulic seals or cylinders.
  
• Leaking hydraulic hoses.
  

Solutions:

• Check hydraulic fluid levels and top off as necessary. Ensure that you are using the correct type of fluid for the system.
  
• Inspect hydraulic lines and fittings for leaks. Replace any damaged hoses or seals.
  
• Clean or replace hydraulic filters if contamination is suspected.
  
• If the issue persists, consult a hydraulic specialist to check the pump and actuator for wear.
  

2. Electrical Issues
Symptoms: Intermittent power loss, failure of dashboard indicators, or machinery shutting down unexpectedly.
Possible Causes:

• Loose or corroded electrical connections.
  
• Faulty wiring or damaged fuses.
  
• Malfunctioning alternator or voltage regulator.
  
• Overheating components causing power cuts.
  

Solutions:

• Inspect the machine’s wiring harness for loose or corroded connections. Clean and tighten connections as needed.
  
• Check fuses and replace any that are blown.
  
• Test the alternator and voltage regulator to ensure they are operating correctly. Replace any faulty components.
  
• Check for overheating issues in electrical components, such as the control panel or wiring, and rectify by improving ventilation or reducing load.
  

3. Engine Overheating
Symptoms: The engine temperature gauge spikes into the high range, and the machine may shut down due to overheating.
Possible Causes:

• Low coolant levels or contaminated coolant.
  
• Clogged radiator fins or cooling system.
  
• Malfunctioning thermostat.
  
• Engine load too high for prolonged periods.
  

Solutions:

• Inspect the coolant levels and refill with the manufacturer-recommended coolant type.
  
• Check the radiator and clean it to remove dirt, debris, or blockages that could restrict airflow.
  
• Test the thermostat and replace it if it’s not regulating the engine temperature properly.
  
• Ensure the machine isn’t being overloaded and allow sufficient cooling breaks during high-load operations.
  

4. Operational Inconsistencies
Symptoms: The machine operates at reduced capacity, or there is noticeable lag in functionality such as delayed hydraulic movement or sluggish conveyor belts.
Possible Causes:

• Clogged air filters or fuel filters.
  
• Worn-out components in the drive train.
  
• Incorrect machine settings or calibration.
  
• Systemic pressure loss in hydraulic or pneumatic systems.
  

Solutions:

• Clean or replace air filters, fuel filters, and intake screens to improve engine and hydraulic performance.
  
• Inspect the drive train for wear, including gears and belts. Replace any worn parts that are not performing as expected.
  
• Check the settings and recalibrate systems as needed.
  
• If the pressure loss is in the hydraulic system, inspect and repair pressure relief valves and check for any blocked lines.
  

5. Material Blockages and Jams
Symptoms: Crushers or screeners fail to process materials efficiently, or materials get jammed in the conveyor system.
Possible Causes:

• Improper material handling or too much material being fed into the machine.
  
• Damaged or worn-out belts or screens.
  
• Blockages in the feed hopper.
  

Solutions:

• Ensure the material being fed into the machine is within the recommended size and capacity.
  
• Regularly inspect conveyor belts and screens for damage. Replace parts that show excessive wear or tears.
  
• Clear blockages in the feed hopper and clean the intake area to avoid material buildup.
  
• Train operators to handle materials properly, reducing the chance of overloading the system.
  

Troubleshooting Vemco Equipment: A Step-by-Step Guide
When diagnosing and fixing issues with Vemco equipment, it’s important to follow a systematic approach to identify the root cause. Below is a step-by-step guide to troubleshoot some common issues:

1. Start with the Power Supply
   • Check the battery and electrical system first. Low voltage or dead batteries are common causes of operational failures.
     
   • Ensure that the alternator and regulator are functioning properly.
     
2. Inspect the Hydraulic System
   • Check for hydraulic fluid leaks or signs of contamination.
     
   • Inspect hydraulic hoses, filters, and seals.
     
   • Perform a test of the hydraulic pump and cylinders.
     
3. Examine the Engine and Cooling System
   • Check coolant levels and ensure that the radiator is clean.
     
   • Inspect the thermostat and cooling system components for proper operation.
     
4. Verify Component Settings and Calibration
   • For machines that require calibration, verify that all settings match the manufacturer’s specifications.
     
   • Recalibrate if necessary to ensure proper performance.
     
5. Look for Blockages
   • In crushers and screeners, make sure the feed hoppers are free from debris.
     
   • Check conveyor belts and screens for material blockages or damage.
     

Best Practices for Maintaining Vemco Equipment
To minimize the risk of experiencing issues with Vemco equipment, regular maintenance and upkeep are essential. Here are some best practices for keeping your Vemco machines in top condition:

• Schedule Regular Inspections: Regularly inspect hydraulic, electrical, and engine components to catch potential issues early. Perform visual checks for leaks, wear, or damage.
  
• Lubricate Moving Parts: Keep moving parts, such as conveyors and crushers, well-lubricated to reduce wear and prevent breakdowns.
  
• Follow Manufacturer’s Maintenance Guidelines: Always adhere to the maintenance schedule outlined in the equipment manual. This includes changing fluids, filters, and checking key components.
  
• Proper Material Handling: Train operators on how to load the machine correctly to prevent overloading and material blockages.
  

Case Study: Vemco Crusher Malfunction
A construction company experienced a breakdown in their Vemco crusher, which was causing delays in material processing. The machine had been sluggish for several days, with unusual grinding noises during operation. Upon inspection, it was found that the hydraulic fluid had become contaminated, causing reduced hydraulic efficiency. Additionally, one of the hydraulic cylinders had developed a small leak, further exacerbating the issue.
The company replaced the hydraulic fluid, cleaned the system, and repaired the leaking cylinder. After clearing the system of contamination and recalibrating the machine, the crusher was back to full operational capacity within hours. The company also implemented a regular hydraulic system inspection schedule to prevent similar issues in the future.
Conclusion
Vemco equipment, while known for its durability and performance, is not immune to the mechanical, electrical, or operational challenges that can occur with heavy machinery. Understanding the common causes of issues like hydraulic system failures, electrical malfunctions, and engine problems is crucial for troubleshooting and maintaining your Vemco machines. By following best practices, performing regular maintenance, and addressing issues promptly, you can ensure that your Vemco equipment remains in optimal working condition, reducing downtime and maximizing productivity on the job site.
