Elevator brake troubleshooting and alignment

Certainly! Elevator brakes are crucial safety components designed to ensure the elevator's smooth operation and passenger safety. Here's an explanation of their function:
Elevator brakes work on the principle of electromagnetism. When the elevator is in operation, the motor drives a system that includes an electromagnet and a metal brake shoe. The electromagnet is energized, creating a strong magnetic field. This magnetic force pulls the metal brake shoe, which is attached to the elevator's moving parts, causing the elevator to move.
When the elevator needs to stop, the power to the electromagnet is cut off. This de-energizes the magnet, weakening the magnetic field. As a result, the metal brake shoe loses its magnetic attraction and is pressed against the stationary brake drum by a spring. This friction between the brake shoe and the drum creates resistance, bringing the elevator to a smooth stop.
In emergency situations or power failures, elevators are equipped with safety systems that engage the brakes automatically, preventing free fall and ensuring passengers' safety.
In summary, elevator brakes function by using electromagnetism to control the movement of the elevator. When the electromagnet is energized, the elevator moves, and when the power is cut off, the brakes engage, stopping the elevator safely.

How to reduce that thumping noise from the plunger activating and deactivating ? Should it be lubricated?

[@axmasterbyalex]

Improper spring tension in the brake mechanism can cause the plunger to engage too quickly or too slowly, leading to thumping noises. Adjust the spring tension according to the manufacturer’s specifications.

[@axmasterbyalex]

Ensure that the brake components are properly aligned. Misalignment can cause uneven wear and noise.

[@axmasterbyalex]

First, check that the gap between the brake liner and drum is the same at both the top and bottom. If it is not, you need to align the brake liner first. If there is still noise, try reducing the gap between the liner and drum.

[@axmasterbyalex]

Apply a suitable lubricant recommended by the manufacturer. Avoid over-lubrication, which can attract dust and cause further issues.

Are the brake lines from asbestos?
