The average value of the number of tests shall be taken and the test situation shall be recorded in Table A1.
Inspect after the test:
a) Check whether the interlocking device and the operating system of the electrical system function normally and whether the action is accurate;
c) Check whether the components of the screen are deformed, cracked, oily, loose, etc.; whether the transmission mechanism is abnormal. 6.9 Static test circuit
The suspension can withstand the test conditions. The induction steel and electrical system ports should be 15mm higher. Any slip should be measured. The test station should be included in the test condition estimation table A3.
6.10 Noise test
6.10.1 The noise test of the window machine shall be carried out in accordance with JG/T5079.2. Test times, record the test results in Table A4, 6.10.2 Background lift rupee measured image is low (6 ~ 10) AR (A), its test value should be subtracted from the background noise correction value in Table 2. If the original noise is lower than the actual noise 6d3 (A). Then the background noise correction value in Table 2
is the difference between the measured sound and the maximum noise
6.11 Safety device inspection
) According to the previous items of Table AF, inspect the various safety protection devices of the business opportunity, and record the inspection results in Table A5.b) The climbing hoist is tested according to the provisions of G since 19135. 6.12 Electric power test
at rated Under heavy oxygen working conditions, the test room is free from lifting, amplitude change, back load and fixed line residual rate of the motor, and the test is carried out once, and the test results are recorded in Table A5.
6.13 Anti-overturning test
6.13.1 Test condition T;
The load of the crane is relatively high:
The load is 2 times the rated load;
The load is 2 times the rated load; (The load should be within the range of 500°) Consider the cumulative moment of the crane, the dead weight of the wire rope and the dead weight of the electric wire rope; (The load should be less than 500°)
6.13.2 Test once, record the test result in Table A7, 6.14 Stress test of station structure
Name. 14.1 The test machine should be completed after the change of 6.~6.13 items: 6, 14.2 Raise the potential ratio to let the whole force analysis type test large, increase its dangerous stress area, through the determination of the measuring point, determine the stomach and direction of the strain gauge,
6.14.3 The test procedure is as follows
) After the load, each strain gauge should recover to the value under the load storage state. When the strain gauge shrinkage exceeds ±3.336/E (see Table 3E for elastic modulus), the cause of the deviation should be found out, and the test should be repeated after correction. When permanent deformation occurs, the test should be terminated. b) The test should be repeated for 10 seconds each time the test position is changed. 6.14.4 Test position and working conditions are as follows: GB 19154--2003 s) Stress tests should be carried out on the main parts of the seedling machine: high virtual force areas, concentrated force areas, elastic bending areas, etc. h) Rated load and dynamic test loads should be added one by one, and stress tests of not less than one time should be carried out: the test results should be recorded in A8. During the test, if the test results show that the product has not been deformed or otherwise adjusted during the test, the test should be terminated and the bottom check should be carried out. 6.14.5 The bottom force should not be greater than the allowable virtual force specified in Table 3.

According to the stress test results at the risk section, the reliability of the structure is analyzed and the design is reasonable, and a conclusion is drawn. 6.15 Reliability test
The machine should be fully tested for 6.5--t, 14 items. The test is carried out under rated load. The test conditions and operating cycles are shown in Table 1. Table 1 Reliability test distribution

Duration of the test, not less than 10,Descend from the upper limit to the lower diameter hole upper limit, reverse the positive belt brake once in the process of descending, return to the working range once, return left and right once, and the length is not less than 5m. The trolley travels one car length. The operator should strictly abide by the operating procedures during the test, and it is not allowed to operate in violation of the rules. If the wiper fails during the test, it should be stopped immediately for inspection and refining, and it is not allowed to operate with a fault. During the test period, it is allowed to perform routine maintenance and maintenance according to the provisions of the instruction manual. 6.15.6 The reliability evaluation index shall be calculated according to the formula (), (5) and (7): 1) The working time before the first fault MTTFF
