Excavator scrap appraisal

For excavators, the technical performance requirements in terms of airtightness, sealing, strength, etc. are relatively high, which is also the key point of its life and scrap life. Generally speaking, the life of an excavator depends on many factors such as the user's usage environment, work intensity, and the quality of the machine itself. However, under normal use and maintenance, the service life of an excavator can reach more than 10 years, and the scrappage period is generally about 15 years.
According to the "Special Equipment Safety Supervision Regulations" and the "Technical Supervision Regulations for Wheeled Mobile Cranes and Engineering Cranes", excavators are classified as special equipment. Therefore, the scrapping standards of excavators need to follow national standards.
As an independent third-party inspection and testing organization under Guoke Holdings, Zhongke Testing has the qualifications for fixed asset scrapping appraisal and can carry out excavator scrapping appraisal services.

1. Service life - Generally speaking, the service life of an excavator is between 6,000 and 8,000 hours. If it exceeds this time or the work intensity is too high, it needs to be considered scrapped.
2. Technical status - Whether the technical indicators of the excavator have reached national standards, whether there are major faults and safety hazards, etc. are all important factors in determining whether the excavator should be scrapped.
3. Economic benefits - Economic indicators such as maintenance costs, energy consumption and production efficiency of the excavator will also have an important impact on whether it needs to be scrapped.

Three excavators of a machinery company were washed away in a certain flood. In order to determine whether the equipment has reached a scrap state, the machinery company entrusted our company to appraise whether the excavators have reached a scrap state.
Appraisal Analysis Results:
Appraisal Analysis The expert team conducted on-site inspection and investigation results on the excavator commissioned for appraisal and evaluation, and made the following suggestions and conclusions:
Identification of the actual technical condition of the excavator and description of defects:
(1) Overall appearance inspection: The upper and lower frames were severely deformed, and the cab was severely deformed.
(2) Power system inspection: The engine assembly is seriously damaged.
(3) Hydraulic system inspection: Hydraulic pumps, multi-way valves, hydraulic motors and other hydraulic components are seriously damaged, hydraulic pipelines are loose and damaged, cylinders are damaged and bent, and steering gears are damaged.
(4) Walking system inspection: The lower frame is severely deformed, and the four wheels are severely damaged.
(5) Working device inspection: The boom is broken.
(6) Electrical system inspection: Instruments, meters, lighting and other electrical system components are severely damaged and missing.
0 In summary, the actual technical condition of this excavator is rated as poor.
1 Since all indicators of this construction machinery have reached scrapping standards after being destroyed by floods, its cost after repair has been greater than its value before being destroyed by floods, and it has no repair and utilization value, so it should be treated as residual value.

1. Preliminary review; before the appraisal, it is necessary to review whether the purpose of the appraisal is reasonable and compliant, whether the appraisal conditions are met, etc., and to make a preliminary determination whether it can be done.
2. Organize materials; confirm that it can be accepted. At this time, you need to provide materials such as a list of fixed assets and reference pictures of the target. Used to calculate appraisal costs and cycles.
3. Fee quotation. After receiving the materials, our agency will organize the technical department to calculate the appraisal fee, which usually takes one to two working days. After calculation, a formal quotation letter will be issued.
4. Sign the agreement; after the quotation letter is issued, submit it to the leaders of the relevant departments for approval. After the leaders' approval, the technical service agreement is signed and the appraisal fee payment process begins.
5, on-site inspection; after our agency receives the appraisal fee, we will arrange on-site inspection by technicians and experts within 1-5 working days. After the inspection, the technician will conduct investigation and analysis based on the materials and prepare a report.
6, issue a report; the report issuance takes about 10-20 working days. After the first draft of the report is formed, it will go through the first, second, and final review, and finally the appraisal report will be issued. At this time, the number of copies of the report will be determined according to the client's needs and mailed to the client together with the invoice. If the client has any objections within 15 days after receiving the report, please reply to our agency. Our agency will organize technical staff and experts to review the appraisal report and provide a reply. If no reply is received within the time limit, our agency will assume that the relevant parties and the client recognize the relevant content in the appraisal report.
