How to maintain and maintain a single beam crane

1. Always check the temperature of the motor casing and the bearing parts of the single-cylinder crane, and the noise and vibration of the motor.

2. When the crane is frequently started, the ventilation cooling capacity is reduced due to the low speed, and the current is large, the temperature rise of the motor will increase very quickly. It should be noted that the temperature rise of the motor cannot exceed the upper limit specified in the specification. Adjust the brake according to the requirements of the motor instruction manual.

3. In the case that the crane is not used frequently and the sealing condition and the use environment are good, the lubricating oil in the crane reduction box needs to be replaced once every six months. When the use environment is bad, it needs to be replaced once every quarter. If it is found that there is water in the tank or there is always foam on the oil surface and it is determined that the oil has deteriorated, it is necessary to change the oil immediately. When changing the oil, it should be replaced according to the oil specified in the instruction manual of the gear box. Be sure to avoid mixing the oil. .

4. The daily maintenance of the reducer can be carried out by referring to the instruction manual of the manufacturer, and the anchor bolts of the reducer should be checked frequently, and the connection should not be loose.

5. Maintenance and maintenance skills of the crane hoisting unit: Always observe the oil tank of the gearbox to check whether the oil level of the lubricating oil is within the specified range. If it is lower than the specified oil level, the lubricating oil must be replenished in time.

6. The grease is required to be filled once every two days in the bearing housing at both ends of the reel. The surface of the reel and the wire rope should be greased according to the situation. (The rolling bearing of the fixed and movable pulley blocks needs to be replenished once a month.
