5.1 Factory test methods and inspection contents
5.1.1 Before the test, conduct an appearance inspection of the lifting mechanism, debug each part that needs to be adjusted according to the design requirements, and run-in according to the provisions of JB/T5945 to ensure that it is in normal technical condition. 5.1.2 No-load operation test
Make the lifting mechanism run at rated speed in both the lifting and lowering directions for 15 minutes each. If there are multiple speed gears, each gear shall be run at no-load for 10 minutes each for lifting and lowering. During no-load operation, change the operation appropriately and check: a) the smoothness of movement;
b) the operation of the brake, clutch, rope guide, etc.; c) whether the fastening and connecting parts are loose or abnormal; d) the sealing condition of each sealing part, and the detection parts and methods shall comply with the provisions of JB/T51060; e) the heating condition of the bearing seat after the end of no-load operation. 5.1.3 Braking capacity test of supporting brake When the supporting brake is fully braked, the drag torque is gradually increased on the drum to at least 1.5 times the rated output torque value, and check whether the drum rotates.
The drag torque should be applied smoothly and not violently. For hydraulic lifting mechanisms supported by balance valves, the inlet and outlet oil channels of the balance valves should be bypassed (i.e., the inlet and outlet oil ports should be connected with oil pipes). 5.2 Methods and inspection contents of type test
5.2.1 For the test items in the type test that are the same as the factory test, the test methods and inspection contents shall be carried out in accordance with the provisions in 5.1. 5.2.2 Measure the mass of the whole machine and directly measure or calculate the center of gravity of the whole machine. The center of gravity is calibrated by the coordinate values of the space coordinate system (see Figure 1) formed by the drum axis and the plumb line and horizontal line passing through the midpoint of the drum axis and perpendicular to the axis. The drum axis is the X-axis, and its direction coincides with the vector direction of the output torque of the drum during lifting; the plumb line is the Z-axis, with upward being positive; the horizontal line is the Y-axis. Ma is the output torque of the drum under lifting conditions. Figure 1
5.2.3 Measure the following parameters:
a) Overall dimensions (total length, total width, total height); b) Relevant dimensions for connection and installation;
c) Wire rope capacity;
d) The bottom diameter D of the drum rope groove, and calculate the ratio of D to the wire rope diameter d (D/d); e) The diameter of the two side edges of the drum.
5.2.4 Load test
Install the hoisting mechanism on the test bench and operate it at various speeds. Raise and lower it according to the rated tension of the outermost wire rope of the drum, so that the wire rope on the drum is wound and withdrawn three times, exceeding 1/3 of the total rope capacity. The following checks are carried out during the test: a) Measure the running speed of the wire rope (take the average rope speed on the outermost layer); b) Check the fixation of the wire rope end on the drum. When the wire rope retains the last 2.5 turns on the drum and 1.5 times the maximum rated tension is applied to the wire rope, the rope end should not come out. 5.2.5 Determination of overall efficiency
Overall efficiency is the ratio of the output power of the drum (rope speed × tension) to the input power of the motor, or to the input power of the hydraulic motor or the input power of the power input coupling, expressed as a percentage. 5.2.5.1 Use a tension sensor to measure the tension of the wire rope, or use the code calibrated by the winch as the applied tension on the wire rope (but its transmission efficiency must be considered at this time); use a tachometer to measure the speed of the drum and record the actual radius of the drum winding, or directly measure the actual speed of the wire rope. The actual output power of the lifting mechanism can be calculated by formula (1) or formula (2): P.-FRn/9. 55....

5.2.5.4 For a lifting mechanism that can be connected to other power sources through a coupling to obtain input power, after measuring the torque value and speed value on the input coupling with a torque meter and a speed meter, the input power P is calculated according to formula (5): Pl=Mne/9.55-

(5)
(6)
According to the rectangular hexahedron method specified in GB/T8194, five measuring points are selected to measure the noise value of the lifting mechanism. That is, in the rectangular hexahedron composed of parallel planes 1m away from the front, rear, left, right and top of the lifting mechanism and the bottom frame plane, the centroid points of the first five measuring planes are used as measuring points. The lifting mechanism works at the maximum rated load and the corresponding rated speed state, and the measurement is carried out using the A weighting gear. The maximum value of the stable meter head (excluding the instantaneous interference value) is read at each point as the measurement value of the point. If the difference between the highest sound level and the lowest sound level at each point is greater than 5dBA), the measurement shall be carried out in accordance with the provisions of GB/T8194. The measured value of each measuring point shall be corrected according to the background noise in accordance with the provisions of GB/T8194. The noise value of the lifting mechanism is expressed as the sound power level LwA of the noise source and calculated in accordance with the provisions of Chapter 7 of GB/T8194+1987.
5.2.7 Braking performance test
JB/T10170
The purpose is to determine the braking capacity and braking smoothness of the brake. 2000
5.2.7.1 The braking performance test is carried out on the lifting mechanism test bench. Use a torque meter to measure the maximum braking torque value of the support brake (referring to the torque value when the brake begins to slip); apply the maximum rated tension to the wire rope of the lifting mechanism, and brake at the rated speed; or open the brake, use a traction device to pull the wire rope to keep the drum running at the rated speed, and brake the brake. Use an oscilloscope to record the torque change during the braking process (the braking torque changes from zero to the maximum value). 5.2.7.2 The following two coefficients are used to characterize the technical characteristics of the braking performance: a) Braking capacity coefficient Kp, calculated according to formula (7): K.=Mimx/M.
Where: Mimnx-

b) Braking torque change rate a;, calculated according to formula (8): Mimax
kN·m/s
Where: Mimax——the maximum braking torque of the brake in actual operation (generally equal to M.), kN·m; (7)
t——braking torque growth time, the time required for the braking torque to reach Mimax from zero during the braking process, s. 5.2.8 Reliability test
The purpose of the reliability test is to evaluate whether the reliability characteristic quantity of the lifting mechanism reaches the required level, check the stability and reliability of the product technical performance, and check the quality of the parts. 5.2.8.1 Reliability test conditions are shown in Table 1.

At each gear, lift 1.1 times of the corresponding rated tension, fully reel in 1/5 of the wire rope length on the drum, and then fully withdraw it for one working cycle
At the maximum lifting tension gear, lift 1.25 times the rated lifting weight of the gear as slowly as possible, brake after the load is lifted off the ground, and slowly increase to 1.5 times the rated tension, stay for 15 minutes, and then slowly drop it Note: Braking must be performed twice in each working cycle (when the wire rope is reeled in and withdrawn). 5.2.8.2 The reliability cycle number distribution shall be in accordance with Table 2. In the absence of special provisions, the working level of the lifting mechanism shall be tested according to the cycle number and distribution scheme specified in the M5 level.
