![]() ![]() If all goes well, then your JGM Bloom lift should be back in working order.įinally, always ensure that the contactor is properly grounded and all wiring is connected securely according to the manufacturer's instructions. Once everything has been checked and replaced where necessary, reassemble the components and test for normal operation. 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. 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. In this case, replacement of the contactor may be necessary in order to restore the normal operation of the lift. 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. ![]() 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. The primary symptom is that when the call button is pressed, nothing happens and the lift does not move. 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.įailing lift contactors are a common cause of the JGM Bloom lift not moving. Lift contactors are essential because they provide protection against potential damage caused by overloading or short circuits. 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. A lift contactor is a type of electrical switch that can control the current supplied to a motor in order to make it move. Lift contactors are an important part of lift maintenance, and they must be regularly checked for functionality. 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. To address this problem, proper maintenance of the equipment should be done regularly and any signs of malfunctions should be addressed without delay. 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. If the lift refuses to move, it could prevent workers from accessing the necessary area or completing their intended task. However, when its lift won't move, it can present a serious issue. This provides access to areas where traditional ladders, scaffolding, and other methods may not be able to reach. It is capable of reaching impressive heights depending on the model. The JLG Boom is a versatile lift and access solution that can be used for many applications. ![]()
