Winget 150T Concrete Mixer
The Winget 150T Concrete Mixer is a robust and reliable machine, trusted for its durability and efficiency in construction projects. However, like any equipment, it can encounter mechanical, electrical, and operational issues that may affect performance.
This knowledge base provides clear, practical solutions to common problems, along with maintenance tips to keep your mixer running smoothly. Whether you’re troubleshooting issues or performing routine checks, this guide will help you minimize downtime, extend the lifespan of your mixer, and ensure consistent, high-quality performance.
1. Engine Fails to Start
Problem:
- Engine won’t start or struggles to turn over.
- Caused by battery issues, fuel problems, or ignition faults.
Solutions:
- Check the battery connections for corrosion and ensure they are tight. Charge or replace the battery if needed.
- Inspect the fuel system:
- Ensure there’s fuel in the tank.
- Check for blockages in the fuel filter or fuel lines; clean or replace if necessary.
- Test the spark plug (petrol engine) or glow plugs (diesel engine) and replace faulty plugs.
- Inspect the air filter for clogs and clean or replace it.
2. Drum Not Rotating
Problem:
- The mixing drum fails to rotate or rotates sluggishly.
- Likely due to drive belt slippage, gearbox failure, or motor issues.
Solutions:
- Check the drive belt for wear, tension, or slipping; adjust or replace as required.
- Inspect the gearbox for oil leaks, wear, or damage. Top up gearbox oil or replace faulty parts.
- If the mixer uses an electric motor, check for power supply issues or motor overheating. Repair or replace the motor as needed.
- Ensure there are no obstructions around the drum that may restrict movement.
3. Excessive Noise or Vibration
Problem:
- Loud rattling, knocking, or vibrations during operation.
- Caused by loose components, worn bearings, or misalignment.
Solutions:
- Tighten any loose bolts, nuts, or fittings on the drum, chassis, or engine mounts.
- Inspect the drum bearings for wear and replace if damaged.
- Ensure proper alignment of the drive system (belts, pulleys, or gears).
4. Hydraulic Problems (If Fitted)
Problem:
- Hydraulic tipping mechanism fails or moves slowly.
- Due to low hydraulic oil, air in the system, or leaks.
Solutions:
- Check and top up hydraulic fluid to the recommended level.
- Inspect hydraulic hoses, seals, and connections for leaks; repair or replace as needed.
- Bleed the hydraulic system to remove any air.
5. Poor Mixing Quality
Problem:
- Uneven concrete mix or clumping.
- Caused by incorrect drum speed, worn paddles, or improper loading sequence.
Solutions:
- Verify the drum is rotating at the correct speed for mixing. Adjust engine or motor as necessary.
- Inspect the mixing paddles for wear or damage and replace if necessary.
- Ensure the correct loading sequence: add water first, followed by cement, sand, and aggregate.
6. Electric Motor Issues (For Electric Models)
Problem:
- Motor does not start or trips the breaker.
- Overheating or humming sound during operation.
Solutions:
- Check the power supply and ensure connections are secure.
- Inspect the motor for overheating; allow it to cool down if needed.
- Test the capacitor or motor windings for faults and replace if defective.
- Ensure the drum is not overloaded, as this can strain the motor.
7. Worn or Damaged Tyres
Problem:
- Tyres wear unevenly or puncture frequently.
Solutions:
- Check tyre pressure regularly and maintain the recommended level.
- Inspect tyres for damage and replace worn or punctured tyres.
- Ensure the mixer is not overloaded beyond its capacity.
8. Rust and Corrosion
Problem:
- Rust build-up on the drum, frame, or other metal components.
Solutions:
- Regularly clean the drum and mixer to prevent concrete build-up and moisture retention.
- Apply rust-inhibiting treatments or paint to affected areas.
- Store the mixer in a dry, sheltered area when not in use.
9. Oil Leaks
Problem:
- Oil leaking from engine, gearbox, or hydraulic system.
Solutions:
- Identify the source of the leak (seals, gaskets, or connections). Replace faulty seals or gaskets.
- Ensure the oil levels are correct and not overfilled.
- Tighten any loose fittings on the engine or gearbox.
10. Clogged Fuel System
Problem:
- Engine runs rough, stalls, or loses power during operation.
Solutions:
- Check and clean the fuel tank, fuel filter, and lines to remove debris or blockages.
- Use clean, good-quality fuel to prevent contamination.
- For diesel engines, bleed the fuel system to remove any trapped air.
General Maintenance Tips:
- Perform daily checks on fuel, oil, and hydraulic fluid levels.
- Clean the drum and mixer components after each use to prevent concrete build-up.
- Grease all moving parts, including bearings and tipping mechanisms, regularly.
- Inspect belts, filters, and tyres weekly for wear and replace as necessary.
