Snorkel lifts, often used in construction, maintenance, and other industries, provide vital access to elevated work areas. These machines are prized for their versatility, but like all equipment, they can occasionally experience issues. One common problem operators face is when a Snorkel lift fails to lift. This can be frustrating, especially on job sites where vertical access is critical.
In this article, we’ll discuss possible reasons why a Snorkel lift may fail to lift, how to diagnose the issue, and how to fix it. We’ll also share some tips for maintaining these machines to prevent future problems.
Understanding Snorkel Lifts
Before diving into troubleshooting, it’s helpful to understand the basic mechanics of Snorkel lifts. These machines are typically powered by hydraulics and include a platform that can be raised and lowered for working at heights. They are often used in construction, maintenance, and warehousing operations where aerial access is necessary.
The lift system in a Snorkel consists of multiple components, including the hydraulic pump, cylinders, and control systems. A failure in any of these components can prevent the lift from functioning properly. Understanding how these parts work together is essential for diagnosing issues when the lift fails to rise.
Common Causes of Lift Failure
Several factors could contribute to a Snorkel lift's inability to lift. Below are the most common reasons:
1. Hydraulic System Issues
The most common cause of lift failure in Snorkel machines is problems with the hydraulic system. If there’s a loss of hydraulic fluid or a malfunction in the hydraulic pump, the lift will struggle to function as intended.
Another possibility is that the electrical system is malfunctioning. The control system, including sensors and relays, may be preventing the lift from responding to commands.
Mechanical issues can also prevent the lift from operating. These are often related to the lift's moving parts, such as the telescoping boom or the lift arm.
Many modern Snorkel lifts are equipped with safety features that prevent the lift from operating under certain conditions. These features can prevent the machine from lifting if certain parameters are not met.
Diagnosing a Snorkel lift that won’t lift requires a systematic approach. Here are the steps to follow:
1. Check the Hydraulic Fluid
Start by inspecting the hydraulic fluid levels. Ensure the fluid is at the correct level and is free from contamination. If the fluid is dirty, it may need to be changed.
Look for signs of hydraulic leaks, such as fluid stains or a noticeable drop in pressure. Leaks in the hydraulic hoses or cylinders will prevent the lift from functioning correctly. If you find any leaks, replace the damaged components immediately.
3. Test the Electrical System
Next, check the electrical connections. Look for loose or corroded wires that might interrupt the signals between the control panel and the lift system.
Examine the mechanical parts of the lift, including the lift arms, chains, and telescoping boom. Ensure that no parts are stuck or damaged. Clean any debris that may be preventing movement.
If the lift is still not working, check for any safety features that might have been triggered. Ensure the machine is on level ground and not overloaded. Check for tilt sensors or other safety mechanisms that could be preventing the lift from rising.
How to Fix the Issue
Once the issue is diagnosed, the next step is to perform the necessary repairs. Here are common fixes based on the diagnosis:
1. Hydraulic Repairs
If you find hydraulic leaks, replace the damaged hoses or seals. If the fluid is low or contaminated, drain the system and refill it with the correct fluid. In cases of significant damage, you may need to replace the hydraulic pump or cylinders.
2. Electrical Repairs
If the issue is electrical, repairing or replacing faulty wiring, fuses, or relays should resolve the problem. If the control panel is malfunctioning, it may need to be reset or replaced.
3. Mechanical Fixes
For mechanical problems, you may need to lubricate or replace worn-out components. In some cases, you may need to replace bearings or other parts that have worn down.
4. Reset Safety Features
If safety features are preventing the lift from working, ensure the machine is on level ground, and check that the load is within the specified limits. Reset the emergency stop system if necessary.
Preventative Maintenance Tips
To avoid issues with your Snorkel lift in the future, follow these preventative maintenance tips:
A Snorkel lift that doesn’t lift can be caused by several factors, from hydraulic issues to electrical problems or mechanical failures. By systematically diagnosing and addressing each potential cause, you can quickly restore functionality to the lift. Regular maintenance and attention to detail can help prevent these problems from occurring in the future, ensuring that your equipment remains reliable and safe to use.
By staying proactive and following the manufacturer's recommendations, you can maximize the lifespan of your Snorkel lift and keep your operations running smoothly.

Several factors could contribute to a Snorkel lift's inability to lift. Below are the most common reasons:
1. Hydraulic System Issues
The most common cause of lift failure in Snorkel machines is problems with the hydraulic system. If there’s a loss of hydraulic fluid or a malfunction in the hydraulic pump, the lift will struggle to function as intended.
- Low or contaminated hydraulic fluid: If the hydraulic fluid is low, the pump may not be able to generate enough pressure to lift the platform. Similarly, contaminated fluid can clog the system, affecting performance.
- Damaged hydraulic hoses or cylinders: Any leaks in the hydraulic lines or damage to the cylinders can prevent the lift from moving. Even small cracks or holes can lead to pressure loss and inadequate lifting power.
Another possibility is that the electrical system is malfunctioning. The control system, including sensors and relays, may be preventing the lift from responding to commands.
- Faulty wiring or connections: Loose or corroded electrical connections can interrupt the signals between the control panel and the hydraulic system, causing the lift to remain stationary.
- Malfunctioning control panel: The control system itself may have a problem, such as a blown fuse or malfunctioning relay, preventing the lift from receiving the signal to rise.
Mechanical issues can also prevent the lift from operating. These are often related to the lift's moving parts, such as the telescoping boom or the lift arm.
- Blockages or stuck parts: Dirt, debris, or rust may cause parts to seize or prevent smooth operation.
- Worn-out components: Over time, components like the lift arm, bearings, or chains may wear out, causing a failure to lift.
Many modern Snorkel lifts are equipped with safety features that prevent the lift from operating under certain conditions. These features can prevent the machine from lifting if certain parameters are not met.
- Tilt or overload sensors: If the machine is on uneven ground or overloaded, the lift may be designed to refuse to raise as a safety measure.
- Emergency stop system: Some models are equipped with an emergency stop feature that halts operation if the system detects any malfunction or potential hazard.
Diagnosing a Snorkel lift that won’t lift requires a systematic approach. Here are the steps to follow:
1. Check the Hydraulic Fluid
Start by inspecting the hydraulic fluid levels. Ensure the fluid is at the correct level and is free from contamination. If the fluid is dirty, it may need to be changed.
- Tip: When changing the fluid, always use the recommended hydraulic fluid specified by the manufacturer. Incorrect fluid can cause long-term damage to the system.
Look for signs of hydraulic leaks, such as fluid stains or a noticeable drop in pressure. Leaks in the hydraulic hoses or cylinders will prevent the lift from functioning correctly. If you find any leaks, replace the damaged components immediately.
3. Test the Electrical System
Next, check the electrical connections. Look for loose or corroded wires that might interrupt the signals between the control panel and the lift system.
- Tip: Use a multimeter to test the fuses, relays, and control panel for any faults. A blown fuse or bad relay can be a simple fix that restores functionality.
Examine the mechanical parts of the lift, including the lift arms, chains, and telescoping boom. Ensure that no parts are stuck or damaged. Clean any debris that may be preventing movement.
- Tip: Regular lubrication of mechanical parts can help prevent rusting and seizing.
