Simple analysis of why Komatsu genuine accessories are loose
Nowadays, the appearance of various types of functional excavators has greatly reduced our labor intensity. However, if the loose fitting between Komatsu's genuine accessories is unimaginable, what factors will cause the excavator parts to loosen? What do I need to do when I use it? If you have encountered this kind of problem while using the excavator and don't know how to deal with it, read the article introduction today, I believe you will have a new harvest.
The reasons for loose loose fittings are as follows:
The vibration of the excavator during construction. Abnormal collisions (including defects) occurred during construction. Strong acid, alkali, acid rain and other rust-resistant construction environments. The elastic bolts do not meet the requirements when replacing parts or repairing parts.
Excavators are inherently hardworking, and the working environment is generally not good. In this case, it is more important to pay attention to safety. Before the engine starts, check the surroundings of the excavator and below. What should I check? Are the nuts and bolts loose? Is there a leak of organic oil, fuel or coolant? There are no abnormalities in the working device, hydraulic cylinder and piping. Before the upper and lower excavators, check the armrests and pedals for loose bolts. Devices such as joysticks, lock levers, rearview mirrors, and wipers cannot be grasped as handrails. Such small details may cause Komatsu's genuine accessories to be damaged and loose, so don't just hang your safety on your lips.
The reasons for the slow movement of the excavator may be: there is no regular maintenance, the hydraulic oil is not replaced on time, the hydraulic oil circuit is blocked, the engine power is insufficient, the output power is too low, the hydraulic pump output is insufficient, and the service diagnostic system can be tested for relevant pressure. Insufficient pilot pressure causes insufficient pressure on the open spool, resulting in insufficient flow and slow motion.
External impurities during mechanical addition can cause a lot of unnecessary damage. Such as mechanical surface scratches, membrane damage to parts wear, such as hydraulic fluids and deterioration. However, for the operation of construction machinery, its complex operating environment, many things can not be avoided, we should raise awareness, try to choose large, flat ground, compared to protect and strengthen mechanical maintenance, reduce unnecessary damage caused by impurities.
Due to the harsh working environment of the excavator, after a long period of use, it will inevitably lead to loose and worn parts. If we have some basic solutions, we can ensure the safety of the excavator if you want to get it.
