What Is A JLG Boom Lift?
A JLG boom lift is a type of aerial work platform that is used to provide access to elevated areas. It consists of a platform or bucket that is mounted on a hydraulic arm, which can be extended or retracted to reach various heights. The platform can also be rotated, allowing workers to access hard-to-reach areas. JLG boom lifts come in different types, including electric, diesel, and hybrid models. They are commonly used in construction sites, industrial facilities, and maintenance projects.
JLG Boom Lift Problems
1. Electrical Problems
One of the most common problems with JLG boom lifts is electrical issues. When the machine experiences electrical problems it can cause the lift to stop functioning making it impossible to reach elevated areas. These problems are usually caused by;
- A faulty battery
- Blown out fuses
Troubleshooting Electrical Problems
- The first thing to check when you encounter electrical problems is the battery. Ensure that the battery is fully charged, and all the connections are tight and secure.
- Check the fuses and circuit breakers.
- Replace any blown fuses and reset any tripped circuit breakers.
- If you have checked the battery, fuses, and circuit breakers, and the issue persists, then it might be a problem with the electrical system’s wiring. In this case then it is best to call a certified JLG technician to troubleshoot and fix the issue.
2. Hydraulic Issues
Another common problem with JLG boom lifts is hydraulic issues. The hydraulic system is responsible for extending and retracting the boom arm and if it malfunctions then it can cause the lift to stop working. These issues include;
- A low hydraulic fluid level
- Faulty hydraulic hoses
- A faulty hydraulic pump
Troubleshooting Hydraulic Issues
- The first step in troubleshooting hydraulic issues is to check the hydraulic fluid level.
- Ensure that the hydraulic fluid level is at the recommended level and that it is not contaminated. If the hydraulic fluid level is low then add more hydraulic fluid to the reservoir.
- If the hydraulic fluid level is not the issue then check the hydraulic hoses and fittings for any leaks or damage.
- Replace any damaged hoses and tighten any loose fittings.
- If you have checked the hydraulic fluid level, hoses and fittings and the problem persists then it might be an issue with the hydraulic pump. In this case then it is best to call a certified JLG technician to troubleshoot the issue.
3. Motor Or Engine Issues
JLG boom lifts come in electric, diesel and hybrid models and each has its unique motor or engine. Motor or engine issues can cause the lift to stop functioning, making it impossible to reach elevated areas. Issue with the motor are caused by;
- A faulty battery
- A faulty fuel tank
Troubleshooting Motor Or Engine Issues
- The first thing to check is the battery. Ensure that the battery is fully charged and all the connections are tight and secure.
- If the battery is not the issue then check the motor for any damage or wear and tear. Replace any damaged parts.
- Check the fuel tank for any contamination or water and replace the fuel filter. Also check the air filter and replace it if it is dirty or clogged.
4. Mechanical Malfunctions
Mechanical malfunctions can also cause JLG boom lifts to stop functioning. These malfunctions can be caused by;
- Wear and tear
- Lack of maintenance
- Environmental factors
Troubleshooting Mechanical Malfunctions
- The first step in troubleshooting mechanical malfunctions is to inspect the lift’s components for any damage or wear and tear.
- Check the pins, bushings and bearings for any signs of damage or excessive wear and replace any damaged parts.
- Check the leveling system and adjust it accordingly.
5. Overheating And Cooling Problems
Overheating and cooling problems can cause JLG boom lifts to malfunction especially during hot weather conditions. The lift’s engine or motor can overheat causing it to stop functioning.
Troubleshooting The Overheating And Cooling Problems
- The first step in troubleshooting overheating and cooling problems is to check the coolant level and ensure that it is at the recommended level. If the coolant level is low then add more coolant to the reservoir.
- If the coolant level is not the issue then check the radiator for any debris or obstructions. Clean the radiator thoroughly and ensure that there are no clogs.
- Check the fan and fan belt for any damage or wear and tear. Replace any damaged parts.
How To Prevent Problems With The JLG Boom Lift
- Regularly inspect the lift’s components for any damage or wear and tear.
- Replace any damaged or worn-out parts.
- Clean the lift thoroughly and ensure that it is free of debris and contaminants.
- Check the hydraulic fluid level regularly and top it up if necessary.
- Change the hydraulic fluid and filters as recommended by JLG.
- Check the battery regularly and ensure that it is fully charged.
- Check the tires for any damage or wear and tear and replace them if necessary.
- Keep the lift’s engine or motor clean and free of debris.
How High Can A JLG Boom Lift Reach?
JLG boom lifts can reach heights of up to 185 feet depending on the model.
Do JLG Boom Lifts Have Weight Limits?
Yes, JLG boom lifts have weight limits and it is essential to adhere to them to avoid accidents and damage to the lift.
Conclusion
JLG boom lifts are essential pieces of machinery in the construction and maintenance industry. However they are not immune to problems and malfunctions. Electrical problems, hydraulic issues, motor or engine issues, mechanical malfunctions and overheating and cooling problems are some of the most common problems associated with JLG boom lifts. It is essential to troubleshoot and fix these problems as soon as possible to avoid downtime and delays in your project.
