4.3.3 The oil pollution reduction level of the micro-pressure system must reach the requirements of B/T11039-1:19/16. 4.3.4 The system should be sealed and have good sealing performance, and the sealing test of 1.25 times the design pressure should be carried out. 4.4 Electrical appliances
4.4.1 The motors mentioned above should be of grade TF55 or above, and the absolute grade is R grade. 4.4.2 The performance of new control electrical appliances and distribution appliances should comply with the provisions of B/T3E31554. 4.5 Parts and components
All purchased and outsourced parts and components should have relevant certificates and should be inspected if necessary: they can be assembled only after they are qualified.
4.6 Appearance
The exterior of the vehicle should be smooth, the paint surface should be bright, the color should be bright, and there should be no burrs, cracks, bubbles and other defects on the surface of the guardrail. 47 Welding quality
The quality of the butt welding of the structure should not be lower than the grade guide seam in B/-3323-1H7. 4.8 Materials
The materials used in the vehicle should meet the requirements of the relevant material industry standards, and the material reports should be complete and the width should be straight. 2
5 Test method
5.1 Performance
CB/T39602002
5.1.1 The main performance of the vehicle should be tested under the conditions of rated load, rated load and rated load. The structure should meet the requirements of 4.1.! 5.1.2 Requirements for work 4: Under the negative load, lift 1.2-to the left of the work table, and keep 161:, and use the holding position to measure the three working buckets. The results should meet the requirements of 4.1 and 2. 5.2 Safety
5.2.1 Under 1.25 times the rated load, the static and dynamic load (running speed is 25=/3) test results of the dock wall car are tested. The requirements of 4.2.
5.2.2 The height of steel lifting inspection is prohibited: the simulation method is verified / T9465.2 [9th issue of 4.5.5, and external force is applied to the protective frame from the same direction, and the external force is observed after the fire protection frame is stimulated. 5.2.3 Use the simulated liquid to stop the system to produce an effective barrier agent to check the vehicle installation: the result should meet the requirements of 1.2.3. 5.2.4 Check the limit switches; the result should meet the requirements of 1.2.1. 5.3 Hydraulic system
5.3.1 Determine the solid particles of the main oil in the liquid: the result should meet the requirements of 4.3.3. 5.3.? 1.25 days under the design force, the hydraulic system is tested for 1% efficiency, maintained at 513, the result should meet the requirements of 4.3.4. 5.4 Electrical performance
5.4.1 Check the shell expansion resistance and insulation grade marks on the right electrical network. The result should meet the requirements of 4.4. ". 5.4.2 According to the test method specified in B/13788-1994, the performance of each collector and distributor is tested. The gauge should meet the requirements of 4.4.2. 5.5 Appearance and welding quality 5.5.1 Visual inspection of the appearance quality of the whole machine: the structure should meet the requirements of 2 and 6. 5.5.24 X-ray inspection of the internal quality of the main load-bearing components. The quality assurance and certificate of inspection materials should meet the requirements of 1.8. 6 Inspection rules 6. 1 Inspection classification: The inspection of automobiles is divided into two types: type inspection and type inspection: 6.2 Type inspection 6.2.1 Applicable scope Type inspection is the trial production and adjustment of new products or products. After production, if there are major changes in materials and processes that may affect product performance, and if there are major differences between the inspection results and the last type inspection, the country shall introduce some inspection agencies to carry out the inspection when required: 6 .2.2 Inspection Items
The type inspection items of the vehicle shall be in accordance with Table 1.
6.2.3 Number of Inspection Samples
The number of products to be inspected for the vehicle type shall be at least 6.2.4 Judgment Rules
If the inspection items of the vehicle type meet the requirements, the type inspection can be considered as qualified: If there are any items that do not meet the requirements, they can be re-inspected after repair. The inspection will be considered as qualified. 6.3 Factory Inspection
CB/T 3950—2002
6.3.1 Scope of Application
Each vehicle dealer shall submit the vehicle to the vehicle management department for inspection before production. 6.3.2 Inspection Items
The number of products to be inspected for the vehicle type shall be at least 6.3.3 Judgment rules
If all pre-inspections of the vehicle meet the requirements,
it is considered that the vehicle has passed the factory inspection. If there are any items that do not meet the requirements, re-inspection is allowed after the inspection. If there are still items that do not meet the requirements after the inspection, the vehicle is judged to be unqualified. Table 1: Inspection items
