What's the matter with the sudden stop of the electric hoist at work?
When the electric hoist suddenly stops running at work, first consider the poor contact of the sliding contact line. When the electric hoist passes through the sliding contact line interface, the electric hoist often stops suddenly, and the motor will be burned due to lack of phase in serious cases.
The types of trolley lines are different, and some trolley lines are in a specially prepared semi-enclosed engineering plastic conduit, embedded with a multi-pole copper guide rail with an insulating slot plate as a power transmission bus. Due to factors such as the quality of the sliding line and the on-site environment,
The plastic casing of the trolley line is fragile and seriously deformed during transportation and installation, which increases the difficulty of installing the trolley line. The interface between the sliding line and the sliding line is prone to misalignment.
As a result, when the collector passes through the interface, there is often poor contact and phase loss or power failure, and the electric hoist suddenly stops.
The second consideration is the current collector, with the built-in spring supporting the sliding carbon brush in contact with the sliding wire. In some coastal areas, due to environmental factors such as high air humidity, the spring is easy to rust and fail, resulting in poor contact between the carbon brush and the sliding wire.
However, there is a chamfer at the position of the carbon brush contact. When the carbon brush enters the uneven sliding wire interface, the electric hoist has low inertia, and the carbon brush contact cannot successfully pass through the interface, resulting in poor contact of a certain phase of the current collector.
In addition to these two cases, we also need to standardize the operation of the electric hoist!
