the daily maintenance work of tower crane be done well
As the saying goes: be prepared. It is also applicable in the field of construction and construction. The daily maintenance of various engineering equipment, including tower lifting, is of great significance to safety production.
However, due to the thousands of knowledge of Tower hanging, and many people's safety awareness needs to be strengthened, so learning tower hanging related knowledge has become everyone's top priority. In this regard, this site summarized the daily maintenance of the tower crane eight military regulations to help the tower crane practitioners understand, how can the daily maintenance of the tower crane do a good job?
The daily inspection and maintenance work of the tower crane mainly includes shift inspection, lubricating oil, pre-inspection, pre-repair and temporary failure removal. These efforts can be summarized in the following eight areas:
First, check the pin connection plate, card board, opening pin, nut is in good condition, there is no loose, found problems to replace in time.
Fasten the bolts of each mechanical coupling, pin shaft, seat and motor.
Third, check the winding situation of the wire rope on the reel, whether there is a change of job, overlap, and chaos of the rope, and whether the rope tail pressure plate bolt is loose or missing.
Fourth, check and debug the safety devices, whether the work performance is normal.
Check whether the main contacts of the distribution box, Circuit terminals and controller are good.
Check whether the connecting bolts and nuts are loose or deformed.
Check the reducers of various institutions, whether there is oil leakage, oil seepage phenomenon, found problems to eliminate in a timely manner.
Eight, check whether the brake is loose or not appropriate, if abnormal should be debugging.
What problems should be paid attention to in night construction?
Some construction tasks are heavy, the time is urgent, and the construction period is tight. Some construction sites must not be carried out at night.
However, in recent years, due to poor visibility at night during the operation of Tower lifting caused a lot of Tower lifting accidents. Therefore, based on the experience of Tower lifting production and use, this site summarizes the following requirements when operating tower lifting at night.
The night construction of the tower hanging should be understood by the nearby residential areas and units. Those who are organized should file with the local construction committee;
Second, during the construction of the tower crane at night, it is required that the tower crane be equipped with obstacle lights. The operation area must be strictly enclosed, and there must also be a light on the enclosure to avoid unrelated personnel and vehicles approaching the construction site;
Third, the tower crane should avoid overtime work during the night operation, especially can not allow the operator to work continuously, so as to increase the risk of accidents in the case of fatigue;
Weather changes should also be strictly observed at night. When there are adverse weather changes such as thunderstorms, strong winds, and hail, work should be stopped immediately and all people should rest.
