To minimize the risk of hydraulic problems and extend the lifespan of the Snorkel TB 60, consider the following preventive maintenance practices:
A construction company using a Snorkel TB 60 lift on a job site noticed a significant decrease in lifting power and a small pool of hydraulic fluid under the machine. Upon inspection, they discovered that a hydraulic hose had developed a crack, causing a slow but steady fluid leak.
The maintenance team replaced the damaged hose, cleaned up the affected area, and refilled the hydraulic reservoir with the proper fluid. They also tested the system for leaks before returning the lift to service. This quick action not only fixed the immediate issue but also prevented further damage to the hydraulic system, allowing the machine to continue working without interruptions.
Conclusion
Hydraulic issues in the Snorkel TB 60 can be frustrating, but with proper diagnosis and timely maintenance, they can be resolved efficiently. Whether dealing with slow boom movement, leaks, or pressure problems, a proactive approach can minimize downtime and prevent costly repairs. Regular fluid checks, cleaning, and inspections are essential to maintaining the health of the hydraulic system and ensuring that the Snorkel TB 60 continues to perform reliably in demanding work environments.
Overview of the Snorkel TB 60
The Snorkel TB 60 is equipped with a hydraulic system that powers various functions, such as lifting the boom, tilting the platform, and extending or retracting the telescopic arm. The system relies on hydraulic fluid to transmit force through cylinders and valves to control the boom and other lift mechanisms. The main components of the hydraulic system include:
- Hydraulic Pump: This is responsible for supplying high-pressure fluid to the hydraulic cylinders and actuators.
- Hydraulic Cylinders: These are used to extend and retract the boom, tilt the platform, and perform other movements.
- Control Valves: These valves regulate the flow of hydraulic fluid, ensuring the boom operates smoothly.
- Hydraulic Reservoir: The tank stores hydraulic fluid and helps maintain pressure throughout the system.
- Hydraulic Hoses and Fittings: These provide the necessary connections for fluid flow and can wear over time.
Despite the efficiency of the Snorkel TB 60's hydraulic system, several issues can occur that hinder its performance. Below are some of the most common hydraulic-related problems that operators may encounter:
1. Slow or Uneven Boom Movement
Cause: Slow or uneven boom movement is often caused by insufficient hydraulic fluid, air in the system, or a malfunctioning hydraulic pump. In some cases, the hydraulic cylinders or control valves could be clogged, restricting fluid flow and leading to sluggish operation.
Solution:
- Check Fluid Levels: Ensure that the hydraulic fluid is at the correct level and top it off as necessary. Low fluid levels can result in inadequate pressure, causing slow movement.
- Bleed the System: If air has entered the system, it can cause uneven or jerky movement. Bleeding the system can remove trapped air and restore smooth operation.
- Inspect the Hydraulic Pump: A malfunctioning or worn hydraulic pump can fail to provide enough pressure to move the boom efficiently. Inspect the pump for wear and replace it if necessary.
- Clean or Replace Control Valves: Over time, control valves can accumulate dirt or debris that restricts fluid flow. Clean the valves or replace them if damaged.
Cause: Hydraulic fluid leaks can occur at various points in the system, such as around seals, hoses, fittings, or cylinders. Leaks can reduce the efficiency of the hydraulic system, causing the lift to fail to reach full height or operate under reduced power.
Solution:
- Inspect Seals and Hoses: Regularly check hydraulic hoses and seals for signs of wear, cracks, or leaks. Replace damaged hoses and seals to prevent fluid loss.
- Check Hydraulic Cylinder: If the boom or other components are leaking, the hydraulic cylinder itself could be damaged. Inspect the cylinders for cracks or worn seals and repair or replace them as necessary.
- Tighten Fittings: Loose fittings can also cause leaks. Ensure all hydraulic connections are properly tightened and that O-rings are intact.
Cause: Issues with the platform’s tilt or positioning may be caused by a problem in the hydraulic circuit controlling the platform tilt. This could be the result of a faulty control valve, low fluid, or a malfunctioning tilt cylinder.
Solution:
- Check Hydraulic Fluid: Low hydraulic fluid can lead to inconsistent or erratic movements. Make sure the fluid is at the correct level.
- Inspect Tilt Cylinders: Check the tilt cylinders for signs of wear, leaks, or damage. If the cylinders are not functioning properly, they may need to be replaced or repaired.
- Clean the Control Valve: A dirty or malfunctioning control valve may not direct fluid flow properly, affecting the platform’s tilt. Clean the valve or replace it if necessary.
Cause: The telescopic boom may fail to extend or retract properly due to issues like low hydraulic pressure, a clogged hydraulic filter, or a malfunctioning extend/retract valve.
Solution:
- Check the Hydraulic Pressure: Low hydraulic pressure can result from a worn pump, clogged filter, or low fluid levels. Ensure the pressure is within the manufacturer’s recommended range.
- Inspect the Hydraulic Filter: A clogged filter can restrict fluid flow and prevent the boom from extending or retracting. Replace the filter regularly as part of the maintenance schedule.
- Examine the Extend/Retract Valve: A faulty extend/retract valve could be preventing the boom from operating correctly. Test the valve and replace it if it is not functioning properly.
Cause: Overheating of the hydraulic system can be caused by excessive load, low hydraulic fluid, or issues with the hydraulic cooler. Overheating reduces the efficiency of the system and can lead to component failure if not addressed.
Solution:
- Ensure Proper Fluid Levels: Low fluid levels can cause the hydraulic system to overheat. Check the levels and add fluid as needed.
- Clean the Hydraulic Cooler: A clogged or dirty hydraulic cooler can cause the fluid temperature to rise. Regularly clean the cooler and ensure it is working efficiently.
- Reduce Load: Operating the lift beyond its rated capacity can lead to overheating. Avoid overloading the machine and ensure that it is used within the manufacturer’s guidelines.
To minimize the risk of hydraulic problems and extend the lifespan of the Snorkel TB 60, consider the following preventive maintenance practices:
