In order to ensure the stable operation of
construction machinery, a comprehensive inspection should be carried out before
and after each use. Before starting, it is necessary to pay attention to the
status of key components such as engine oil, fuel tank, antifreeze, air filter,
etc., to ensure that the oil level is normal, the quality is good, and the
pollutants are eliminated in time. At the same time, check the fan belt,
turbocharger, hydraulic oil and gear oil to ensure that there is no damage, no
leakage, and the oil level is moderate. The battery power should also be
sufficient, and the pipeline and line are connected tightly without loosening.
During the starting process, observe
whether the instrument display is normal, pay attention to the smooth start of
the engine, and avoid continuous long time starting. Under low temperature
conditions, preheating operation is also required.
After starting, the alarm information of
the instrument should be checked again to ensure that there is no abnormal
prompt. Then, observe the engine emission smoke color, sound and lower exhaust
condition to judge its running state. The hydraulic system is also the focus of
the inspection. It is necessary to listen to the running sound of the hydraulic
pump, valve, cylinder and motor to ensure that there is no abnormal sound, and
manipulate the action to check its normality.
In addition, do not forget to lubricate the
pin shaft and lubrication point of the working device, and add butter in time
to ensure the flexible operation of each component.
Comprehensive inspection can not only
detect and eliminate potential faults in time, but also extend the service life
of construction machinery and improve operation efficiency. Therefore, each
operator should master this inspection guide to ensure the safety and smooth
operation of each operation.
