Supply of 20 Bodies Metal Movable File Optimizer: The construction made of Rigid Knock Down 0.8 thk. CRCA Steel conforming to IS: 513 Gr.D. Each body block consists of 1 Main unit & then Add-on units, each unit has 5 loading levels formed by 4 nos. adjustable shelves for 1980 Height body. The bodies including shelves shall be treated antirust surface treatment & are coated with epoxy polyester powder. It will involve an 8-step treatment consisting of Hot water rinse, knock of degreasing, degreasing, cold water rinse, phosphate, cold water rinse, and passivation & dry off oven treatment. The testing of paint shall be done for various physical & chemical properties as per IS: 101and then oven baked with a controlled temperature of 180 deg.C to 200 deg.C. It should be made of 0.8 thick CRCA steel conforming to S: 513 Gr.D or DD. It should have max load bearing capacity of 100 Kg uniformly distributed per shelf. Shelves should be mounted on support brackets & shelf level can be adjusted at approx. 25.4 pitch. The shelf shall be1180 mm in length and can hold up to 13 nos. of box files of size 85mm x 345mm x 285mm. if no Cradle pair is to be provided in the 400 mm deep body as per the requirement of the customer. It should consist of ‘Z’ angle 1.0 thick sheet & pipe of ½” Dia. The Under structure is a welded frame suitably fabricated to bear the loads based on configuration. Main channel, body-fixing channel, U-channel and Z-channel. All the components shall be made out of HR sheet 3 mm thk. Conforming to IS: 2062. Static Drive / Last Drive – 1200 x 2 X 396 (Depth) X 80 (Height), Twin Drive - 1200 x 2 X 796 (Depth) X 80 (Height). The under structure, after pre-treatment, is coated with final finish consisting of epoxy polyester powder coat of approved color & shade with a Dry Film Thickness of minimum 40 microns. The drive type movement of units shall be by rotating a PU hand wheel. The hand wheel comprises of a welded metal frame which is then covered by PU using insert-molding process. The metal frame shall be made of 3 mm thk. HR conforming to IS: 2062. The hand wheel shall be connected to the rollers through a ‘Sprocket-Chain’ arrangement mounted on the side of the body. Each movable under structure is provided with 4 rollers of which 2 are driving and 2 are driven. The driving rollers are connected to the sprocket-chain arrangement through a connector tube. Through this assembly the input from hand wheel is transferred to the driving rollers which then move the entire unit along the rails. On LD under structure additional 2 nos. of a special anti-tilt bearing assembly is fitted to the under structure. This prevents lateral movement as well as tilting of body. The roller assembly comprises of a die-cast step wheel, 2 deep-groove ball bearings and a MS shaft. The step wheel is made of cast steel and is fitted onto the MS shaft using a feather key. The two ball bearings are then fastened on either side of the step wheel using circlips. This entire roller assembly shall be snap-fitted into wheel housing. The wheel housing shall be fixed in the U-channel of the under structure using machine screws. This wheel-housing shall be made of engineering plastic material made by injection-molding process. The entire roller assembly is designed to withstand the maximum loads of the body. The ‘sprocket-chain’ arrangement is covered by a 1 mm thk. CRCA sheet Drive Unit Cover with dimensions 1202mm x 398mm x 87mm and is fixed onto the side of the body. The PU hand wheel shall be rigidly fixed at suitable height on side of the body & projects out of cover by another 99.0 mm. Fixed unit does not have the Drive Unit Cover. Each Drive type unit will have a Locking Knob near the Drive wheel for manual locking of individual units when a person is using those units. Knob should be rotated to unlock position when units are to be moved again. A centralized locking arrangement shall be provided on drive unit cover. A cam lock and lever arrangement shall be fitted on the drive unit cover of the last movable body. After all bodies are brought together, the bodies should lock using their respective knobs. The cam lock is then turned to lock position. This locked cam lock ensures that the knob of the last body remains in the locked position unless the cam lock is unlocked. This in turn ensures that the entire layout remains locked. The nuts & bolts shall be galvanized / blackodized / Zn Plated. It consists of ‘C’ section 2 mm thk HR sheet & Square 25.4mm X 2mm thk ERW tube – both connected by screws. The above Metal Movable File Optimizer has to be Green Guard / Gree Pro Certified for Ul. The rail channels shall be as per approved layout with 800 aisle space. The level holder shall be made of aluminium extrusion of length 396mm for LD/SD and 796mm for TD, fitted on to front cover of body.
