The load test of the crane should be carried out at the lifting height and radius of the basic model specified in the design. 4.5.1 Rated load test
Check whether each mechanism operates normally, measure the rated speed of lifting, rotation, amplitude change, walking and the noise in the driver's cab. During the test, the accuracy and sensitivity of the torque limiter and the lifting weight limiter should also be tested. When the crane is in normal operation, it shall be tested according to the working conditions in Table 1, and the test of one working condition shall not be less than 3 times per year. For the measurement of each parameter, take the average value of the three measurements and record its value in Table A1. Table 1 Rated load test Boom luffing Trolley luffing The boom is measured at the rated speed at the rated speed at the maximum lifting weight at the minimum lifting weight at the rated speed at the rated speed at the rated speed at the maximum lifting weight at the rated lifting weight at the rated speed ... During the lifting and lowering process, the normal control is performed for no less than three times. The maximum lifting weight is hoisted in the whole lifting amount, and the maximum amplitude of the lifting and lowering is performed within the corresponding lifting height of the hoist. For cranes with variable speed hoisting mechanisms, the rated lifting load corresponding to each lifting speed shall be hoisted and normal braking shall be performed for no less than three times during the descent process of the maximum amplitude corresponding to the lifting load. The crane shall be 500tum off the ground, and the luffing of the load in two directions shall be performed at the rated speed between the minimum amplitude and the maximum amplitude corresponding to the lifting load. The luffing time shall be measured when the boom luffing exceeds the maximum rotation one-way travel distance. The measured value is not less than 20 m. Note: ① For jib cranes that cannot change the length of the boom under load as specified in the design, the boom change length test under load may not be carried out according to the provisions of this table. ② For other mechanisms with variable speeds, tests should also be carried out and each working speed should be measured. 4.5.2 Static load test with 25% overload The test load is 125% of the rated lifting capacity. If there are special requirements for the test load value, it can be determined by negotiation between the user and the design unit and the manufacturer. Determine the horizontal static displacement of the connection between the tower body and the boom, the noise in the driver's cab and the torque limiter, and the accuracy of the lifting capacity limiter. Measure the speed of various actions and the starting and braking time of each mechanism,Determine the horizontal static displacement of the connection between the tower body and the boom. Measure each working speed. During the static load test with an overload of 25%, the torque limiter, lifting weight limiter and brake can be adjusted. After the test, they should be readjusted to the original specified value. Assess the strength and structural bearing capacity of the crane. After unloading, check whether the crane has visible cracks, permanent deformation, paint peeling, loose connections, and damage that affects the performance and safety of the crane. The test results are recorded in Table A1. The static load test with an overload of 25% is carried out according to the working conditions in Table 2. During the test, the boom is located at two positions: 45° and perpendicular to the track. Table 2 Static load test with 25% overload
At the maximum amplitude, lift 125% of the corresponding rated lifting weight
Lift 125% of the maximum lifting weight, at the corresponding maximum amplitude of the lifting weight

4.5.3 Dynamic load test with 10% overload
The test load is 110% of the rated lifting weight. Lift
The lifting weight is lifted 100~～200mm from the ground, and the weight is gradually increased on the hook to 1.25 times, and stay for 10 minutes. When there are special requirements for the test load, it can be determined by the user, the design unit, and the manufacturer through consultation. Check the flexibility of the operation of each mechanism of the crane and the reliability of the brake. After unloading, check whether there are any abnormal phenomena such as looseness and damage of the mechanism and structural components. The test results are recorded in Table A1. Remarks: The test is carried out according to the working conditions in Table 3, and the combined action test is carried out according to the design requirements. The test of each working condition shall not be less than three times, and the next start shall be carried out after each action stops steadily.
