290HC Mast Section Characteristics of Construction Machinery in the Grinding Period and Its Use and Maintenance
After a construction machine such as a tower crane is delivered, it is generally stipulated that there will be a grinding period of about 60 hours(some are called a running period). This is stipulated by the manufacturing factory according to the technical characteristics of the initial use of the construction machinery. The grinding period is an important link to ensure the normal operation of the construction machinery, reduce the failure rate and extend its service life.
However, some users ignore the special technical requirements of the new machine grinding period due to the lack of common knowledge about the use of construction machinery either because of the tight schedule or because they want to gain revenue as soon as possible. Some users even think that anyway, the manufacturer has a contract repair period.

The machine is broken and the manufacturer is responsible for maintenance. Therefore, the machine is overloaded for a long time during the grinding period, resulting in frequent early faults of the machine, which not only affects the normal use of the machine. Shorten the service life of the machine, but also because of machine damage, affecting the progress of the project.
Therefore, the use and maintenance of construction machinery should be paid full attention to. Below, the following analysis is made on the characteristics, use and maintenance of the construction machinery during the grinding period.The characteristics of the construction machinery during the grinding period
