Table 1 JG-1.6X60 JG1.6×75 JG-2×80 JG-2×110 Maximum lifting lifting speed Lifting length Transmission ratio JG-2.5×130 JG-2.5×180 JG-3×200 JG-3×270 JB/T6380—92 ContinuedTable 1 Maximum lifting lifting speed Note: The maximum lifting speed is the approximate effective value when winding in one layer based on the nominal diameter of the reel. 4 Technical requirements Lifting length The product shall comply with the requirements of this standard and shall be manufactured in accordance with the drawings and technical documents approved by the prescribed procedures. The product shall work in a machine room without explosive media and with an air temperature of 540°C. 4.2 The materials and accessories used in the product shall comply with the relevant provisions of the current national standards. The product's wearing parts, spare parts and general parts shall ensure interchangeability. Before painting the product, the rust removal quality of the surface of steel parts shall comply with the provisions of St2 level in GB8923. The appearance of the paint layer is not allowed to have defects that affect the appearance, such as pinholes, bubbles, cracks, shedding, sagging and missing coating. Before assembly, the pipes and fittings of the lubrication and hydraulic systems must be pickled and coated with anti-rust oil. The noise sound pressure level of the product at the control panel position shall not exceed 85dB (A). Spindle device White spots and cracks are not allowed inside the spindle, and the requirements for inclusions and crack defects are as follows: dynamic Within 2/3 of the diameter of the spindle axis. Single, sporadic, scattered defects and dense defects.
