Introduction
The 2000 Snorkel TB120 is a high-reach telescopic boom lift designed for demanding construction and maintenance tasks. Equipped with a 120-foot platform height and a 62-foot horizontal reach, it offers versatility and power. Central to its operation are the motion packs—hydraulic assemblies that control the boom's movements. Understanding their function and maintenance is crucial for optimal performance.
Motion Pack Functionality
The TB120's motion packs are hydraulic systems that manage the extension, retraction, lifting, and lowering of the boom. They consist of hydraulic cylinders, valves, and motors that work in unison to provide precise control over the boom's movements.
Common Issues and Troubleshooting
A construction company faced intermittent boom movement issues with their TB120. Upon inspection, they discovered that the hydraulic fluid was contaminated, leading to sluggish movements. After replacing the fluid and cleaning the system, the boom's performance improved significantly, highlighting the importance of regular maintenance.
Conclusion
The motion packs of the 2000 Snorkel TB120 are vital for its operation. Understanding their function, recognizing common issues, and performing regular maintenance can ensure the boom lift operates efficiently and safely.

- Check and top up hydraulic fluid levels as needed.
- Possible Causes:
- Erratic Boom Movements
- Possible Causes:
- Faulty proportional valves
- Electrical issues affecting control signals
- Faulty proportional valves
- Solutions:
- Test and calibrate proportional valves.
- Inspect wiring and connections for integrity.
- Test and calibrate proportional valves.
- Possible Causes:
- Complete Loss of Motion
- Possible Causes:
- Blown fuses or tripped circuit breakers
- Failure in the main hydraulic pump
- Issues with the motion pack's internal components
- Blown fuses or tripped circuit breakers
- Solutions:
- Replace blown fuses and reset circuit breakers.
- Test and replace the main hydraulic pump if necessary.
- Disassemble and inspect the motion pack for internal failures.
- Replace blown fuses and reset circuit breakers.
- Possible Causes:
- Regular Inspections: Conduct routine checks of hydraulic fluid levels, hoses, and connections.
- Cleanliness: Keep the motion packs and surrounding areas clean to prevent contamination.
- Component Testing: Periodically test proportional valves and other critical components for proper function.
