In addition to the certain terms specified in GE83, this standard also uses special technical provisions such as F: 3.1 The maximum tensile force obtained at the cable opening when the warp drum is designed as a nominal continuous system. 3.2 Nominal speed
The maximum rope supported by the warp drum under the action of the mooring load. 4 Product classification
4.1 Type
According to different installation methods, it can be divided into the following three types: Type 4 - A relatively convenient belt drive is specially installed on the deck (see Figure 13); Type 4 - A simply installed on the deck with the source motor lifted upside down under the deck (see Figure 13). Type C: The main engine and the prime mover are installed on two layers of A-type main engine (Figure 3) Figure 1A type

Empty cutting return (center of disc)
Note: (D steel code resistance control width is 1520N/mmOr the maximum torque of the protective device is calculated by the average force of the affected parts. Hours, the calculated force shall not exceed 95% of the service limit of the material; c: When the stress of the affected parts is calculated by the design rope breaking load, the calculated stress shall not exceed 5% of the material service. 6 Test method
6.1 No-load test
Continuously run for 30min at the nominal speed, 15min each in the forward and reverse directions, and after the electric disc is turned for 30min, it is decided to change gears, and each turn can be reversed. Gmin. Reduce the disc 3Cmin before or after operation, it should be run at the lowest set speed and the highest speed in the forward and reverse directions for 2min each.
6.2 The system is to be driven at a nominal speed of 50 mm2 under the action of the system load. 6.3 Controlled brake device test drive
According to the load reverse control brake device test specified in 5.1.3, the electric disc should be able to automatically brake when it is stopped or in the braking position or the power is cut off. For the hydraulically driven disc, a certain amount of slip is allowed for the brake, but the slip rate should not exceed 1 minute:
6.4 Measurement and inspection items
6.4.1 Measure the current under no-load and system load. The current under the load of the electric disc should not exceed the rated current of the motor. |tt||6.4.2 The measurement of the axiom under the load of the tether shall comply with the provisions of Table 1. 6.4.3 The measurement of the no-load speed (short speed> shall comply with the provisions of Table 1. 6.4.4 Measure the oil pressure of the main oil case, etc. under no-load and cable load. 6.4.5 Measure and check the oil leakage of the pressure-receiving system, reducer, etc. 6.4.6 Check whether the hydraulic system is stable. 6.4. Check whether the effect plate runs smoothly and whether there is any sieve noise. 6.4.8 Check the safety and reliability of the control brake device. For the effect island support sliding plate driven by wave pressure, the inspection rules
7.1 Factory inspection
GB/T45551995
According to 6.1 for no-load test, and the alcohol tester shall be carried out in accordance with the relevant provisions of 6.4. .2 Type inspection
7.2-1 When the winch is under the following conditions, it is necessary to carry out the following type inspection! B. New product trial production,
b. Transfer to production;
c. Batch production inspection 20 series,
7.2.2 Carry out type test according to the items listed in 6.1~6.3, and the measurement and inspection items of the test shall be in accordance with the relevant provisions of the system. 8 Marking, packaging, transportation and storage
8.1 The product shall be marked permanently according to the following items, including the product name;
h. Product model || tt||d. Inspection mark:
e. Date of manufacture:
f. Name of manufacturer,
R.2. Packaging of each component: Packing should be fixed, 8.3. The product should be fixed during transportation and have anti-separation and anti-spreading measures. 8.4. The product should be stored in a well-ventilated place.
