Introduction and maintenance of electric chain hoist parts

Why is electric chain hoist more popular than other electric hoists? In addition to its solid structure, simple, flexible and convenient operation, it mainly has the following components:

1. The motor brake is a unique brake design. Its characteristic is that even when the power is turned off under a full load, the brakes will act immediately.
2. The hook and fuse are forged with high tensile steel, and are heat-treated to meet the requirements of strength and hardness. The lower hook can rotate 360° horizontally and is equipped with a hook fuse to ensure take-off and landing. Smoothness.
3. Phase sequence protection relay. Its circuit design can protect and avoid the motor from burning out when the phase of the electric chain hoist motor power supply is connected wrongly.
4. The upper and lower limit switches can automatically cut off the power when the limit is exceeded during lifting and lowering to prevent the chain from exceeding and ensure safety.
5. The emergency stop switch can be used to stop the operation of the electric chain hoist in an emergency. It is a red mushroom-shaped button, located above the button switch. When the button is pressed, the power of the electric chain hoist will be cut off and the button will be automatically locked. Rotate clockwise to release the button and restart the electric hoist.

How to maintain the above parts of the electric chain hoist?

1. The gear has been in operation for 500 hours from the start. It is necessary to check whether the amount of lubricating oil is sufficient, and then check the lubricating oil regularly every three months.
2. Always keep the parts of the electric chain hoist dry, and it is strictly forbidden to abuse the equipment so as not to affect the durability of the machine.
3. If the electric chain hoist needs to be operated outdoors, please install protective devices.
