In the world of aerial lifts and platforms, machine reliability is paramount. Equipment failures can be both dangerous and costly. A common issue faced by operators of upright Tiger lifts after hose replacement is a bouncy or unstable platform. This article will explore the reasons behind this problem, provide tips for troubleshooting, and offer maintenance advice to avoid such issues in the future.
Understanding the Problem: Bouncy Platform After Hose Replacement
The issue at hand involves a bouncy platform on an Upright Tiger aerial lift following the replacement of hydraulic hoses. After replacing a hydraulic hose or performing related maintenance on these machines, it is not uncommon for operators to notice that the platform becomes unsteady or bouncy when raised.
This erratic platform movement may be caused by several issues within the hydraulic system. Given that aerial lifts are typically used in high-stakes environments, ensuring they operate smoothly is crucial for both the safety of the operators and the efficiency of the machine. Let’s delve deeper into the potential causes of this issue.
Possible Causes of a Bouncy Platform
Several factors can contribute to a bouncy or unstable platform after hydraulic hose replacement. These may include:
1. Air in the Hydraulic System
To prevent future occurrences of bouncy platforms and ensure the longevity of your Upright Tiger aerial lift, regular maintenance and careful handling during repairs are essential. Here are some helpful tips:
1. Regular Hydraulic System Maintenance
A bouncy platform on an Upright Tiger after hydraulic hose replacement is a common issue that can be resolved by carefully addressing the possible causes. The most likely culprits include air in the hydraulic system, incorrect hose routing, low hydraulic fluid levels, or issues with the hydraulic valve or pump.
By properly diagnosing the problem, following the correct maintenance procedures, and using quality parts, operators can ensure their lifts remain in top operating condition, preventing unnecessary downtime and improving safety on the job site.
Remember, aerial lifts like the Upright Tiger are vital for many high-reach tasks, so regular checks and proper maintenance are crucial for ensuring reliable performance.

Possible Causes of a Bouncy Platform
Several factors can contribute to a bouncy or unstable platform after hydraulic hose replacement. These may include:
1. Air in the Hydraulic System
- Cause: One of the most common causes of erratic platform behavior is air in the hydraulic lines. When the hoses are replaced, air may enter the system if the lines are not properly bled or purged.
- Symptoms: The platform may bounce, hesitate, or have uneven movements, especially when raised or lowered.
- Solution: To fix this, operators need to properly bleed the hydraulic system. This can be done by cycling the boom several times and ensuring that all air is purged from the lines. If the system has a designated bleed valve, it should be used according to the manufacturer’s instructions.
- Cause: Improper installation of the new hoses can result in kinks or obstructions that prevent the smooth flow of hydraulic fluid. Additionally, if the hoses are routed incorrectly, it can affect the pressure or flow rate in the hydraulic system.
- Symptoms: The platform may experience jerky or unsteady movement, as the hydraulic fluid struggles to flow correctly.
- Solution: Carefully inspect the hose routing to ensure it follows the manufacturer’s guidelines. Ensure the hoses are free of bends, kinks, or any obstructions that could limit fluid flow.
- Cause: If the hydraulic valve that controls the movement of the platform was not properly installed or adjusted during the hose replacement, it could lead to issues with pressure regulation.
- Symptoms: The platform could exhibit erratic motion or fail to maintain a steady position once raised.
- Solution: Double-check the hydraulic valve’s installation. Ensure that it is functioning correctly and that all connections are secure. Test the valve for leaks and verify that it is properly adjusted to maintain appropriate pressure levels.
- Cause: If the hydraulic fluid level is low or there is a leak in the system, the fluid may not be able to reach the necessary pressure to operate the lift correctly.
- Symptoms: The platform may move slowly, unevenly, or bounce when raised.
- Solution: Check the hydraulic fluid levels and top them up if necessary. Additionally, inspect the system for any signs of leakage. Leaks could be due to improperly tightened fittings or damaged seals during the hose replacement process.
- Cause: A malfunctioning hydraulic pump or motor can cause fluctuations in pressure, leading to a bouncy or unstable platform. After replacing the hoses, if the pump or motor is not delivering consistent fluid pressure, it may cause the platform to behave unpredictably.
- Symptoms: The lift may not rise at a consistent speed, or the platform may bounce or struggle to maintain its position.
- Solution: Inspect the hydraulic pump and motor for proper operation. Test the output pressure and compare it with the manufacturer’s recommended levels. If the pump or motor is faulty, it may need to be repaired or replaced.
To prevent future occurrences of bouncy platforms and ensure the longevity of your Upright Tiger aerial lift, regular maintenance and careful handling during repairs are essential. Here are some helpful tips:
1. Regular Hydraulic System Maintenance
- Check hydraulic fluid levels regularly and top them up as necessary.
- Inspect the hydraulic hoses and fittings for any signs of wear or damage.
- Clean the hydraulic filter periodically and replace it as recommended by the manufacturer.
- When replacing hydraulic hoses, always use the correct replacement parts and follow the manufacturer’s guidelines for hose routing and installation.
- Be sure to fully bleed the hydraulic system after hose replacement to remove any air from the lines.
- After any hydraulic maintenance, thoroughly test the lift before use. Check for smooth operation, stable platform movement, and consistent pressure.
- If any issues are noticed, immediately troubleshoot the problem and address it before using the machine further.
- Always use high-quality, OEM (original equipment manufacturer) parts when replacing hoses or other components. Subpar parts can lead to system inefficiencies or failures over time.
