Scope

Scope: This document specifies the type and structure, marking, requirements, test methods, inspection rules, marking and packaging, accompanying documents, transportation and storage of steel cable drag chains. This document applies to steel cable drag chains (hereinafter referred to as "drag chains"). Main technical content: 5. Requirements 5.1 Appearance quality 5.1.1 The outer surface of the drag chain shall be smooth and flat, and shall not have obvious deformation, cracking, bumps, scratches, or rust marks. 5.1.2 There shall be no burrs on the relative moving parts at the cutting, bending, punching, and drilling processing locations. 5.2 Performance 5.2.1 The maximum moving speed of the drag chain shall not be less than 65 m/min. 5.2.2 The maximum moving acceleration of the drag chain shall not be less than 20 m/s2. 5.2.3 At the maximum moving speed, the noise pressure level of the drag chain shall not exceed 68 dB (A). 5.2.4 The safe service life of the drag chain shall be not less than 1 million cycles (reciprocating). 5.3 Dimensional accuracy 5.3.1 Bending radius error: The actual bending radius of the drag chain shall be within a range of -5% to 0 compared with the marked bending radius. 5.3.2 Surface roughness: The surface roughness of the contact surface between the drag chain and the load-bearing object shall be Ra ≤ 6.3 μm. 5.3.3 Side bending: The side bending shall be tested in accordance with the provisions of 6.3.3, and the side bending shall not exceed 5 mm/m.
