* The document is not valid on the territory of the Russian Federation. GOST R ISO 898-1-2011 is valid. - Database manufacturer's note.

2.4. The maximum deviations of linear dimensions from the nominal ones, as well as the surface roughness of the planks, must correspond to those indicated in Figures 2 and 3.

2.5. Maximum deviations of the diameters of the holes of the clamping strips from the nominal ones are in accordance with GOST 25347-82.

3. COMPLETENESS

3.1. Parts of crane rail fastening units must be supplied by the manufacturer as a set.

The kit should include:

- details in accordance with table 4;

- technical documentation in accordance with the requirements of GOST 23118-78.

Table 4

	Designation	Designation

Note. It is allowed, by agreement between the manufacturer and the consumer, to supply thrust and clamping strips separately from bolts, nuts and washers.

4. ACCEPTANCE RULES

4.1. The thrust and clamping bars must be accepted by the technical control of the manufacturer.

4.2. Acceptance of planks is carried out in batches.

The batch must include planks of the same designation, manufactured using the same technology. The batch size of planks is established by agreement between the consumer and the manufacturer and should not exceed 1000 pieces.

4.3. To randomly check the linear dimensions and surface roughness of the planks, 5% of the planks are selected from each batch, but not less than 5 pieces. If, when checking the selected strips, there turns out to be at least one product that does not meet the requirements of this standard for one of the indicators, a double number of samples taken from the same batch is re-tested according to this indicator. In case of unsatisfactory results of re-inspection, the batch of planks is not subject to acceptance.

4.4. The consumer has the right to control the quality of the planks, while observing the acceptance rules and applying the control methods established by this standard.

5. CONTROL METHODS

5.1. Control of the linear dimensions of the slats should be carried out with a metal measuring ruler in accordance with GOST 427-75 and a caliper in accordance with GOST 166-89.

6. PACKAGING, LABELING, TRANSPORTATION AND STORAGE

6.2. The rules for marking containers with strips must comply with those established by GOST 14192-77 *. The marking must contain the following markings:
________________
* The document is not valid on the territory of the Russian Federation. GOST 14192-96 is in force. - Database manufacturer's note.

Name or trademark of the manufacturer;

- symbol of the brand of fastening unit;

- symbol of the bar (without indicating the standard number);

- batch number;

- number of details;

- Quality Control Department stamp;

- gross weight.

6.3. Transportation of planks is permitted by any type of transport, provided they are protected from contamination and mechanical damage.

6.4. During storage, containers with slats must be protected from contamination and precipitation.

7. INSTALLATION INSTRUCTIONS

7.2. Assembly welding of the strips should be carried out after straightening the rails. The thickness of the weld is 6 mm.

7.3. The type of electrodes must correspond to that indicated in Table 5.
E42A

7.4. After completion of installation work, parts of fastening units must be cleaned, puttied, primed and painted, and the paint coating material must match the coating material of the crane beams.
