Maintenance During Running-in Period Of Single Girder Crane

Maintenance during running-in period of single girder crane

Crane, also known as crane, refers to a multi-function lifting machinery that can lift heavy objects vertically and carry horizontally within a certain range. The working characteristic of single-girder crane is intermittent movement, that is, in the working cycle of picking up, moving, unloading and other actions, the corresponding mechanisms work alternately. With the development of society and the construction of cities, cranes are increasingly developed and used in the market.

Single-girder bridge cranes are widely used in workshops, warehouses, stockyards, etc. in machinery manufacturing workshops, metallurgical workshops, petroleum, petrochemicals, ports, railways, civil aviation, power stations, papermaking, building materials, electronics and other industries. 

Crane running-in period maintenance:

The running-in period is an important step to ensure the normal operation of the crane, reduce the failure rate, and extend its service life. After a crane leaves the factory, there is generally a running-in period of about 60 hours (some are called a run-in period), which is stipulated by the manufacturing factory based on the technical characteristics of the crane in the initial stage of use.

1. Since the 15 ton crane is a special vehicle, the operator should receive training and guidance from the manufacturer, have a full understanding of the structure and performance of the machine, and obtain certain operation and maintenance experience before operating the machine. The product use and maintenance instructions provided by the manufacturer are essential information for the operator to operate the equipment. Before operating the machine, be sure to read the use and maintenance instructions and perform operation and maintenance according to the requirements of the instructions.

2. Pay attention to the workload during the running-in period. The workload during the running-in period should generally not exceed 80% of the rated workload, and a suitable workload must be arranged to prevent overheating caused by long-term continuous operation of the machine.

3. Pay attention to frequently observing the indications of each instrument. If there is any abnormality, stop the machine in time to eliminate it. If the cause is not found and the fault is not eliminated, the operation should be stopped.

4. Pay attention to frequently checking the level and quality of lubricating oil, hydraulic oil, coolant, brake fluid and fuel oil (water), and pay attention to checking the sealing of the whole machine. During the inspection, it is found that there is too much oil and water, and the cause should be analyzed. At the same time, the lubrication of each lubrication point should be strengthened. It is recommended that the lubrication points should be filled with grease during each shift during the running-in period (except for special requirements).

5. Keep the machine clean, and adjust and tighten loose parts in a timely manner to prevent loosening from aggravating wear and tear of parts or causing parts to be lost.

6. After the running-in period is over, the machine should be subject to mandatory maintenance, inspection and adjustment, and pay attention to the replacement of oil.

In short, the requirements for 15 ton crane use and maintenance during the running-in period can be summarized as: strengthening training, reducing loads, paying attention to inspections, and strengthening lubrication. As long as you pay attention to and implement the maintenance and repair of the crane during the running-in period as required, the occurrence of early failures will be reduced, the service life will be extended, the operating efficiency will be improved, and the machine will bring you more benefits.
