The electric single-beam crane uses electric hoist as the lifting mechanism, and attention should be paid to the daily inspection of the equipment during use. The editor will sort out the daily inspection items of the gourd-type single-beam crane for everyone .

1. Inspection items

Before starting work every day, the person in charge of the site should run the truck empty and confirm the following:

1. Pay attention to special obstacles within the walking range of the operator.

2. Observe whether there is any abnormality in the orbit from the ground.

3. Press the button of the flashlight door and press the mark to make up, down, left and right movements accurately and sensitively.

4. Whether the action of the brake is sensitive, safe and reliable.

5. Whether the lifting limit switch can move accurately.

6. Whether there is abnormal sound or vibration.

7. Whether the pulleys in the hook pulley group can rotate sensitively, and whether there is oil shortage. Whether the hook can rotate flexibly, and whether the anti-loosening device of the hook nut is abnormal. In addition, whether the steel wire rope or chain has fallen off from the pulley or chain.

8. Whether the steel wire rope can be wound on the drum correctly.

9. Whether there is oil shortage on the wire rope or chain.

2. Description of daily inspection tasks

The daily inspection is the on-site inspection of the hoist crane to confirm the daily work before starting work every day.

The characteristics of the hoist-type single-beam crane is that it is rarely used by the same person all day, and there are many situations in which several operators alternately operate and use it. For each crane, a person in charge of the site should be assigned to conduct daily inspections.

1. Because the hoist-type single-beam crane is operated on the ground, in order to operate safely, always pay attention to obstacles on the ground and confirm the safety of walking.

2. The majority of hoist cranes have no inspection platform. It is very difficult to climb on the rail beam for inspection every day. In fact, there are almost no accidental obstacles on the track, so it is decided to observe the track and the stop from the ground. (Resistor).

3. Because it is dangerous to act in the opposite direction of the flashlight door button sign, it is necessary to solve the action according to the sign direction.

4. The inspection of the lifting limit switch should be carried out after determining the sensitivity and reliability of the brake.

5. When the crane movement is not stable or there is abnormal noise or vibration, it means there is a malfunction.

In order to ensure the safe operation of electric single-girder cranes, companies must do a good job in the daily inspection of the cranes to ensure the safety of the equipment and avoid affecting production.
