Shelves technology standard manually: the production process materials, process using the GB/T13667.3-2003 manual-intensive the bookshelf technical conditions, industry standard DA/T7-92 of the People's Republic of China and GB/T13668-2003. Product must be detected by the product quality supervision department finds. (1) intensive counter rail welded by a 20 × 25 mm stainless steel solid square steel and not less than 3 mm thick steel plate bending forming shield group, hard chrome plated surface. Track embedded installation orbit every 200 mm have a filler block secured to the hard ground. The rail mounting accuracy should be in line with national standards. Tender unit commitment rail mounting accuracy. (2) Material requirements: a high-quality cold-rolled steel column: 1.5mm, peg board: 1.2mm, shelf, side guards, door: 1.0mm; rail seat, base: 3.0mm high-quality hot-rolled steel sheet rail side rails 20 x 25 stainless steel solid square steel. (3) for a three-column frame steel structure, mainly by rail, chassis, drive mechanism, and the frame body (including the column, the the shelf support plate, shelf, door, roof, side guard panel) (zero). The top shelf has a dust-proof device, equipped with a 15mm special anti-aging PVC magnetic seal between the columns to form a fully enclosed between the two, the facade of columns and intermediate move out of air locks and brakes, each Shelves the closed total available lock to form a closed overall. Each column is removed after separate brake. At the bottom of a rodent control, anti-down device, the entire frame body should have a good dust-proof, water-proof, rodent-proof, moisture-proof, anti-theft and security functions. (4) at the end of the beam install anti-inverted frame, to prevent frame body tilt. (5) Shelves transmission system is mainly composed of iron wheel, drive shaft, seat belt bracket bearings, precision roller chains, waving body parts. Precision roller chain motorcycle chain, transmission gear flange processing. Two side shafts are driving shaft to drive any one can easily make it in front of the columns in the overall mobile central axis biaxial Transmission Shelves to the left, to the right in both directions can be easily smooth drive, the transmission ratio is 1:5. Can guarantee the movement speed, but also to ensure that the hand is not difficult, in line with national standards, each standard column shaking force no greater than 12N. The handle shake lightweight, flexible, no noise, the handle can be folded to avoid obstacles to movement. (6) Every fight double-sided fabric adjustable hanging hole on the column, after four molded bent into a rectangular cylinder, on the next three columns coupled file welded design, structure should be solid and reasonable, beautiful, atmospheric, not easily deformed . (4) Chassis segmentally welded the overall assembled, heavy chassis structure; chassis height 150mm, should be connected firmly, transport, easy to install, the chassis assembly with bolts (M8x20 with double spring washers, 8.8) connections are tight chassis, after the end of the beam are washed with 52 × 47 rectangular slot the assembly section size of 50 × 40 column into this rectangular slot position, insert a length of 150 mm. Support roller chassis rungs large special dedicated mold molded into shaped external force, the frame body without any deformation. Bidders heavy-duty chassis structure diagram. (7) requires the lower end of the column directly into the the chassis fixed rectangular hole, column locking clamping block to hold fast to the chassis, bolts (M6x15 with double spring washers, 8.8) tightening, the upper end of the column and roof bolts (M8X15 / 70 with double spring washers, 8.8) fastening the column supported by the casing card dead, so that the top of the pole to form a whole, and enhance the overall rigidity of the frame body. (8) linked to both ends of the shelf support plate dedicated mold punching bending design, the valgus linked structure, which used between the a dedicated drawing dies molded two attractive appearance oval steps to strengthen hole, the bottom of the bend , using a dedicated drawing dies throwing small molded four fixed shelf. When the shelf is placed on the shelf support plate, four throwing Ding should be firmly fixed. All assembled smooth, solid, no noise, need to be free to adjust the spacing of the layers. The column hanging hole spacing adjustable. (9) shelf dual shaped like six bending, surface treatment, reasonable structure, easy to use, each standard load-bearing 80kg. (10) guards positive vertical three-mile clip color bump guard, visual effects, elegant, seamless, the rack body shape should be beautiful. (11) move the middle column has a parking brake device side column equipped with a parking brake device and locks that total lock, access to safe, convenient and effective.
