How long is the service life of a 28-ton excavator hydraulic rotary grab?

[BONOVO]

In the fields of large-scale engineering construction, port operations, and mining, 28-ton excavators have become the mainstay with their powerful power and excellent operating capabilities. The matching "28-ton excavator hydraulic rotary grab" plays a key role in material grabbing, loading and unloading. For users, the service life of the grab is a crucial consideration, which is directly related to operating efficiency and operating costs. So, how long is the service life of the "28-ton excavator hydraulic rotary grab"? This is affected by a combination of factors.

1. The material determines the basic life
The material of the grab is the fundamental factor affecting its service life. High-quality "28-ton excavator hydraulic rotary grab" is usually made of high-strength alloy steel. This steel has excellent wear resistance and impact resistance. For example, when loading and unloading sand, gravel, coal and other materials at the port, the grab needs to grab and unload frequently. High-strength alloy steel can effectively resist the friction and collision of materials and reduce wear and deformation. Compared with grabs made of ordinary steel, grabs made of alloy steel can extend their basic service life by 2-3 years under normal working conditions. Some high-end grabs also use special heat treatment processes in key parts, such as bucket teeth and cutting edges, to further improve their hardness and wear resistance, so that these vulnerable parts can still maintain good performance during frequent operations, thereby significantly extending the service life of the entire grab.

2. The significant impact of operating conditions
The difference in operating conditions has a huge impact on the life of the "28-ton excavator hydraulic rotary grab". If the grab is mainly in a milder environment, such as carrying loose bagged goods, its wear rate is relatively slow. However, if the grab is used to grab hard ore in a mining environment or to grab construction waste containing steel bars on a construction site, the challenges faced by the grab are completely different. Hard ore and steel bars will cause strong impact and wear on the bucket body and bucket teeth of the grab. Under such harsh working conditions, the service life of the grab may be shortened to half or even less than that under normal working conditions. According to statistics, in general mining operations, if the grab works 8 hours a day, its service life may be 1-2 years; under relatively relaxed logistics handling conditions, the service life of the grab can reach 3-5 years for the same working hours.

3. Maintenance is crucial
Regular and professional maintenance is the key to extending the service life of the "28-ton excavator hydraulic rotary grab". Daily maintenance includes cleaning the various parts of the grab, timely removing attached materials, and preventing materials from corroding the surface of the grab. At the same time, the hydraulic system should be checked to ensure the cleanliness and oil volume of the hydraulic oil to avoid component damage caused by hydraulic oil contamination or insufficient oil. In terms of maintenance, regularly lubricate the pins, joints and other active parts of the grab to reduce friction. Checking and timely replacing wearing parts such as bucket teeth can also ensure the normal working performance of the grab. Through good maintenance, the service life of the grab can be extended by 1-2 years. Some large enterprises have established a complete equipment maintenance file and maintain the grab according to the prescribed maintenance cycle, so that the grab can still maintain a high operating efficiency after many years of use.

4. Operational specifications cannot be ignored
The degree of operational specifications of the operator is also closely related to the service life of the "28-ton excavator hydraulic rotary grab". Skilled and standardized operators can reasonably control the grab force and speed of the grab according to the characteristics of the material and the working environment. For example, when grabbing heavier materials, close the grab slowly and smoothly to avoid the instantaneous impact force from damaging the grab structure. Irregular operations, such as high-speed impact on materials and excessive overload grabbing, will greatly accelerate the wear and damage of the grab. According to the survey, cases of grab damage due to improper operation account for about 30% of the total damage cases. The service life of the grab operated by professionally trained operators can be extended by 0.5-1 year compared to the grab operated by untrained personnel.

In summary, the service life of the "28-ton excavator hydraulic rotary grab" is not fixed. Ideally, the grab can last 5-8 years with high-quality materials, mild working conditions, good maintenance and use by standardized operators. However, if the material is poor, the working conditions are bad, the maintenance is lacking, and the operation is not standardized, the service life of the grab may be only 1-2 years. Therefore, the user should consider various factors comprehensively, and take measures such as selecting high-quality grabs, improving the working environment, strengthening maintenance, and training operators to maximize the service life of the "28-ton excavator hydraulic rotary grab" and improve the operating efficiency.
