Process for Submission and Acceptance of Second hand Excavators

Through Shanghai HuachengUsed excavatorThe Import Machinery Division understands that when importing second-hand excavators, customs need to conduct comprehensive inspections, hygiene and epidemic prevention tests, etc. on the second-hand excavators. Later on, it will beSecond hand excavator pricesThe main inspection items for evaluation include the following:

When conducting safety inspections on second-hand excavators, it is necessary to start the excavator and conduct dynamic inspections to ensure that the mechanical and electrical safety of the excavator complies with China's mandatory standards and regulations. During the dynamic inspection process, it is necessary to inspect areas where potential risk factors may exist. The distribution of hazardous factors is very extensive, and any rotating, movable parts, live parts, sharp edges, etc. may cause harm to the users. The project involving safety inspection is a second-hand excavator（http://www.shcteng.com/）The arrival inspection is of utmost importance, and relevant personnel should inspect the following items.

(1) In terms of safety protection. All components of the excavator should be intact and securely connected, and any exposed rotatable parts should be equipped with protective covers.

(2) Regarding the driver's cabin. The driver's cab should be firm and reliable, with intact glass, flexible door and window closure, secure door locks, and anti slip measures for ladder handrails and passages.

(3) In terms of components. Important structural components such as the boom, arm, track frame, chassis, and rotating platform should not have severe plastic deformation or cracks, and there should be no obvious welding defects (such as porosity, slag inclusion, lack of penetration, and lack of fusion) at the weld joints. Bolts and rivets should not be loose.

(4) Regarding the engine. The engine can start smoothly, run smoothly, idle steadily, without any abnormal noise; The lubrication, cooling, and exhaust system components of the engine should be intact and operate well; The hydraulic oil pressure is normal.

(5) In terms of hydraulic system. The hydraulic system has no signs of aging, cracking, damage, or oil leakage.

(6) In terms of electrical systems. Ensure that all instruments, meters, and lighting fixtures are undamaged. The system should be equipped with work lights, indoor lighting, and reliable starting sound alarm devices. The performance of lighting and signal devices should comply with the provisions of GB/T20418; The electrical wires are not aged or exposed, the electrical connections are in good contact, and the connectors are not loose; The display (such as visual display, alarm signal) can work normally; The battery should be securely fixed and equipped with a protective cover.

(7) In terms of rotary braking. To have a safe and reliable rotary braking system.

(8) In terms of braking performance. It should comply with the requirements of GB/T9139.1, which means parking and braking on a slope of not less than 40%, then turning the excavator 180 °, and parking and braking for 5 minutes in each state to ensure that the equipment does not slide down (the working device of the excavator should be in the transport position during the test).

(9) Overturning protection. If a second-hand excavator is equipped with a tipping protection device, a rolling protection device, or a falling object protection device, it should comply with the provisions of GB/T19930, GB/T17771, and GB/T17922, respectively.

When conducting hygiene, environmental protection, and anti fraud inspections on imported second-hand excavators, the following inspection items may be included.

(1) In terms of environmental protection. According to GB/T7586, the noise limit at the driver's position should be less than 90 dB (A) during testing.

(2) According to GB/T8190.4, determine the emissions of pollutants from excavators.

(3) In terms of overall sealing performance. After working continuously for 3 hours, the leakage should not exceed 2 drops within 10 minutes.

(4) In terms of hygiene. The appearance should be neat, all components should be intact, and the connections should be tight. Check whether there are any dirt, household waste, soil, dead medical animals or their feces, nests and other residues attached to various parts of the second-hand excavator. In the actual inspection process, it was found that the excavator track had accumulated soil and other phenomena, which should be identified as unqualified according to the standard requirements.

(5) For other general inspection items involving non safety, hygiene, and environmental protection, compliance verification is usually carried out based on trade contracts with the aim of preventing fraud, such as the quantity and specifications of accessories.

In summary, for key projects involving personal and property safety, health, hygiene, environmental protection, etc., if they do not meet the mandatory requirements of China's national technical specifications, the entry-exit inspection and quarantine institutions should make rectification requirements to the consignee and require them to make a written rectification report until the re inspection is qualified. Products that are still not qualified after rectification should be judged as unqualified and treated as second-hand excavators for return.
