Single-chain electric hoist What are its structural characteristics? How should it be maintained on a daily basis? If you’re not very familiar with this topic, please refer to the following overview. Structural Features of a Single-Chain Electric Hoist As follows:

1. Metal structural parts

This kind of Crane steel structure The main girder is fabricated by rolling steel plates. The U-shaped槽 and box-web girders are constructed from I-beams. The transverse girders are also fabricated by rolling steel plates into U-shaped槽 and then welding them into box girders. Bolts are used to connect the main girders and transverse girders.

2. Transmission Mechanism

LDA electric Crane steel structure The driving and braking are accomplished by a conical-rotor brake motor. The transmission employs “Clutch” gear transmission.

3. Electrical Equipment

The operating motor is a single-speed, asynchronous, conical-rotor brake motor, with an operating speed of 20 m/min.

4. Electric hoist

The CD1 electric hoist consists of three main components: the lifting mechanism, the operating mechanism, and the electrical equipment.

Every day, electric chain hoists operate continuously in the warehouse to handle large volumes of goods. To prevent mechanical failures caused by prolonged use, regular maintenance is essential. Below, we will provide a detailed overview of the maintenance methods and key features.

Daily Maintenance of Single-Chain Electric Hoists We will proceed as follows:

1. Check frequently Single-chain electric hoist Check the temperature of the motor housing and bearing areas, as well as motor noise and vibration, for any abnormal conditions.

2. Single-chain electric hoist During frequent starts, low rotational speed and high current result in reduced ventilation and cooling capacity, leading to a rapid increase in motor temperature rise. It is important to ensure that the motor’s temperature rise does not exceed the maximum limit specified in its nameplate data, and that the brake is adjusted in accordance with the requirements outlined in the motor’s operating manual.

3. In Single-chain electric hoist When the crane gearbox is not frequently used and the sealing conditions and operating environment are good, the lubricating oil should be changed every six months; under harsh operating conditions, it should be changed every quarter. If water is present in the oil tank or there is persistent foaming on the oil surface, and it is confirmed that the oil has deteriorated, then Need Replace the oil immediately. When changing the oil, strictly follow the specifications for the lubricant outlined in the transmission’s operating manual, and avoid mixing different types of oil.

4. Single-chain electric hoist Daily maintenance can be carried out in accordance with the manufacturer’s user manual; regular inspections are required. Electric hoist The foundation anchor bolts must be securely fastened.

5. Single-chain electric hoist Maintenance and upkeep tips: Regularly inspect the oil sight glass of the reducer to verify that the lubricant level is within the specified range. If the level falls below the prescribed mark, Need Replenish the lubricant promptly.

6. Lubricating grease shall be applied to the bearing housings at both ends of the drum every other day, and the drum surface and wire rope shall be lubricated with grease as required.

The above Yes This introduction to the features and daily maintenance of single-chain electric hoists is sure to help you use and protect your equipment more effectively.
