4.1.1 The wheel is used (HT2M in T49, R1:7 in [.10 system, 1.2 The silver system of the system
42.1 The parts must be qualified after appropriate inspection: the purchased parts must have a certificate of qualification before they can be selected for assembly. 4.2.2 The oil pump and other certificates must be matched with the core surface. The components must not have any defects that affect the performance of the system: 4.2.3 The clearance between the fork channel wheel and the pre-directed steel ball and the nest guide should not be more than +1mm. 4.2.4 For the structure, the wheel and its rotating parts and components should be fully active, and no jamming is allowed. The lifting tear market note is that when the lifting plan is lowered, the medicine is not recommended, and the potential fork can be from the highest point to the lowest point from the bottom. 4.3
3.1 For each load, the rated lifting capacity and the load center distance shall be marked on the permanent part xc in the position specified in Figure 3.
4.3.2 The load is to be subjected to humidity test, and the test load is 3 times of the designed lifting capacity. 4.3.3 Within 15 minutes under the constant load, the natural drop value of the load shall not exceed F5mm. 4.4 Technical requirements for short-circuit system
4.4, 1 The hydraulic efficiency shall not be less than 1%. 4.2 When the efficiency is 25% of the constant load, the hydraulic The system flow shall not have a avoidance pool, leakage is soft, 4.43 vehicles out!

4. 7.1 The lifting force bar is recommended to be under dynamic and static load. The static safety system should be greater than 5:4 (normal control, including wheel and other organic materials are not allowed to have cracks, deformation, irregularities, etc.,
47. Double car surface painted yellow: the goods are painted with evil gold, and the machine can choose the color of the inner surface that is not easy or cannot be selected. Before actual assembly, verify that the paint has changed. There are mosquitoes, and the installation has a rapid rise. The gloss of the painted surface is subject to observation. The small limit difference of the size on the drawing is according to Class C in 181. 5 Test methods and inspection rules
5.1.1 The test environment temperature is the inner temperature. 5.1.2 The test tower is a horizontal filter and the test platform is also changed. 5.1.3 The test load is a homogeneous cube, and its side distance from the center is times that of the load. S.1.4 The dry system should be concentrated with oil. 5.2 Each unit is manufactured in-house and undergoes factory inspection. In addition to the production guarantee, the factory inspection includes: 1) no negative pressure test: 2) system volumetric efficiency inspection: 3) overload control test. 5.3 The type inspection will be carried out at least once a year during the production meeting. During the trial production or design of the vehicle, when the material is seriously modified, the inspection should be carried out based on the sample of the batch of forklifts. The number of samples shall be increased by 1% (the number of parts in the batch is less than 3) according to the annual strict inspection! 3.2 Type inspection includes new requirements for more than one item, and the inspection should include the following: 1) Natural reduction inspection of forklifts:
b) Total qualitative inspection.
5.4 Inspection and confirmation
5. 4.1 Steps to confirm
Turn the pulling needle through the daily reading, close the liquid circuit, ": the lower point of the promotion speed: the loan failed to reach the highest height in the middle of the pool: the control chart is opened, and the cargo can be packaged at the lowest position. In the loan: rise, fall but not track, do not hold leakage and other phenomena or hear abnormal sound
5.4.2 summer memory and efficiency inspection
lead the determination load is still at the center of the ten standards: the most sincere position of the cargo document point rises to 1mm's situation flow: single record of loss efficiency 1 read honest product evaluation! The value should comply with the capacity management efficiency specified in 44.1 (calculation:

Cargo on the 1500mm related to the station about the number of times, 5.4.3 Super color load Under the condition of 125 times the new load, the goods and the full lifting should be less than 5 times, the unloading store liquid system is not allowed to read the phenomenon, the enterprise lubrication is balanced, the lifting and lifting equipment and the soil should be relatively stable, the permanent deformation, the continuous tearing, the connection parts are stuck and the product must be safe. 5.4.4 The qualification of the natural drop value of the forklift is 1500% of the rated load, and the natural drop value of the lean fork will be measured after 3min to meet the requirements of 4.3.3.5 Stability test
Stability test is carried out on the test platform. As shown in Table 3 and Table 4~7, if the test result does not meet the requirements of Table 2, the sweeping leg system must be able to resist the retreat of the parts, adjust the eccentric sleeve, and limit the sound of the frame and the push, and the locking mechanism is tested at night.
