Shelves structure requires one, the assembly binding; Shelves structure diagram 2, manual and electric Shelves are assembled modular structure, with a set of manual operation manual Shelves structure; electric Shelves with electric and manual two operating agencies . They are mainly a combination of columns, shelves, hanging plates, side panels, chassis and other components made; shelves, peg board should be able to adjust the height of the vertical direction of the column, the column hanging plate hole spacing is 50mm. 3, according to the provisions laid track, install transmission, anti-fall devices; 4, the track can be installed bolt or nail, prominent or flush with the ground surface (embedded); 5, set the dust, rodents, moisture and sealing devices. Manufacturing workers poor one, after each standard section assembled outside dimensions (length, width, height) limit deviation of ± 2mm; 2, after each standard section assembly, the gap in the side panels and seams on the backs of less than 2mm; 3, after the rail mounting, deviation of parallelism of not more than 1mm / m, the whole grow in 2mm; parallelism deviation of the same cross-section is not more than 1mm / m, the whole grow in 2mm; 4, each of the two tracks parallelism deviation of less than 2mm; rail docking at the height difference is not greater than 0.3mm. 5, straightness after assembly consisting of sections of the bottom beam is not greater than 0.5mm / m, the whole grow at 2mm. Manufacturing and processing one, after all sheet metal parts, machined grinding burrs, no cracks, no scars; 2, all welded parts, welding firm, welding marks smooth, flat; 3, between a combination of product components to maintain interoperability transsexuals.
