JLG Boom - Lift Won't Move. What Are the Reasons and Fixes?

The JLG Boom is a versatile lift and access solution that can be used for many applications. It is capable of reaching impressive heights depending on the model. This provides access to areas where traditional ladders, scaffolding, and other methods may not be able to reach. However, when its lift won't move, it can present a serious issue.

If the lift refuses to move, it could prevent workers from accessing the necessary area or completing their intended task. This could lead to delays in projects and can potentially create a hazardous situation if someone attempts to use the lift while it is dysfunctional.

To address this problem, proper maintenance of the equipment should be done regularly and any signs of malfunctions should be addressed without delay. So, when assessing what may be causing the lift of the machine to seize, the following factors are a good way to start your diagnosis:

1. Failing Lift Contactors

Lift contactors are an important part of lift maintenance, and they must be regularly checked for functionality. A lift contactor is a type of electrical switch that can control the current supplied to a motor in order to make it move.

The contactors are connected to the elevator motor and its associated load circuit, providing automatic safety shut-off when the door is opened or closed and preventing overloads from occurring in the event of a power surge.

Lift contactors are essential because they provide protection against potential damage caused by overloading or short circuits. If the lift's motor suddenly experiences too much current, it may short out and result in serious repair costs or worse-injury to passengers due to a malfunctioning system.

Failing lift contactors are a common cause of the JGM Bloom lift not moving. The primary symptom is that when the call button is pressed, nothing happens and the lift does not move.

To assess the cause of this problem, manual checks should be carried out and tools such as a digital multimeter used to test for voltage conditions on the contactor. If all tests come back fine and there are no obvious signs of wear or damage, then it's likely that either the contacts have become fused together due to arc erosion, or they are severely worn out due to age or contamination. In this case, replacement of the contactor may be necessary in order to restore the normal operation of the lift.

When replacing the contactor, ensure that the correct type is installed-either a single-pole or double-pole contactor depending on the lift's requirements. Additionally, check for signs of debris such as dirt and dust inside the contactor housing which can cause further damage to the contacts if left unchecked. Once everything has been checked and replaced where necessary, reassemble the components and test for normal operation. If all goes well, then your JGM Bloom lift should be back in working order.

Finally, always ensure that the contactor is properly grounded and all wiring is connected securely according to the manufacturer's instructions. Never attempt to repair or replace any electrical components without proper knowledge and experience in this field as it can be dangerous.

If you are unsure of how to proceed, then seek help from a qualified electrician.  With these considerations in mind, you should now have a better understanding of why faulty lift contactors can cause the JGM Bloom lift not to move and ways of fixing this issue.

2. Malfunctioning Joystick

The joystick on the JLG Boom Lift is a vital component of the machine's operation. It serves two primary functions: controlling and adjusting the boom lift. When using the joystick, an operator can adjust the boom up or down, drive forward or backward, and rotate it to gain access to different areas.

However, if there is a malfunction with the joystick, this could significantly affect its ability to perform these tasks properly. A broken or stuck joystick can cause several problems such as slow acceleration and deceleration, reduced turning radius, difficulty in reaching desired heights or angles with the boom lift platform, or even complete loss of control.

To prevent any accidents from occurring due to a faulty joystick mechanism, operators should always monitor the condition of their joystick before using the JLG Boom Lift. They should also be aware of any unusual behavior that may indicate a problem with the joystick, such as sluggish movement or an inability to move it in certain directions.

If any issues are detected, they should report them to their supervisor immediately and not attempt to use the lift until it has been repaired.

Joystick issues in the JGM Bloom can be one of the most common causes for its lift not moving. To start, one should assess the cause of this issue by considering the symptoms and performing manual checks.

When dealing with a power problem, users might notice that the joystick is unresponsive or there may be LED lights on it indicating a lack of power or connection. In such cases, checking all connections between the joystick and base unit can help determine if there is an issue with wiring or parts that need to be replaced.

On other occasions, physical damage might be causing a malfunctioning joystick. Users may observe frayed wires around control buttons or broken cables inside the device itself. If these signs are visible upon inspection then it is likely that the part is broken and needs to be replaced.

Sometimes, the issue may not be visible upon inspection and users need to go deeper into diagnostics. This can involve running diagnostic software on the joystick itself or connecting some kind of tester device to it to identify any issues with its internal components. In these cases, it may be necessary to replace several parts like potentiometers, encoders, and switches to fix the problem.

3. Solenoid Terminal Wire Fault

As protection against overheating from electrical overload, the solenoid terminal uses two wires, each connected to its own solenoid of the same size and power, which are wired in series so that they share the load evenly between them. This helps reduce heat buildup in the system and prevent damage caused by an overloaded circuit.

Additionally, if one wire fails, it will not affect the other since they are independently powered. This type of protection also prevents shorting out as there is no direct contact with any other component in the system. The solenoid terminal ensures reliable performance and extended life for your machine's electrical systems.

The JLG Boom is equipped with two additional solenoid terminals that serve as safety measures in the event of a wire failure. If one of the wires in the solenoid terminal fails, the other will still be able to carry the load and keep the system running. This helps reduce costly downtime due to electrical problems and ensures your JLG Boom is always working properly and safely.

A solenoid terminal wire fault is one of the most common causes of a lift not moving on the JGM Bloom. The issue can be easily assessed by looking for symptoms and checking manual connections, as well as using tools such as multimeters to perform voltage tests.

Most often, the problem occurs due to loose or corroded connections within the terminal wiring. In some cases, however, the wiring itself may have simply become damaged over time.

The solution to this problem is fairly straightforward. Just replace any faulty parts with new ones. This includes inspecting all terminals and solenoids for corrosion and dirt buildup that could cause issues with connections which can then lead to a fault in power transfer from the lift's motor.

If corrosion or dirt is found, it should be cleaned and the wiring checked again. Additionally, if any of the wires appear to be broken or frayed, they should be replaced with new ones as soon as possible.

Inspecting all components for proper connection is also essential in solving this problem. This includes the lift motor's relay terminals, power cables between the motor and control panel, switch connectors at the control panel, and sensor switches on the lift platform.

If any of these connections are loose or not making secure contact, they should also be tightened up or replaced with new parts as necessary. Once all potential issues have been addressed, test the system by running it through its normal cycle and see if it works correctly. If it does, the problem has been solved.

In addition to parts replacement and connection checks, it's also important to ensure that all connections are properly insulated with rubberized gaskets or other weatherproofing materials.

This will help prevent any future faults due to water damage, as well as extend the life of the lift system. By following these steps and replacing any faulty components, the JGM Bloom lift should be back in working order again in no time.

Conclusion

There are a few other elements that could seize the lift of the JLG Boom but the ones mentioned here are the most common reason why it happens.
