Specifications include, but are not limited to: It is the intent of this specification to describe an all-purpose conveyor type hopper spreader body, constructed from 304 Stainless Steel throughout (including nuts, bolts, springs, fastener’s, piping, ¼” and smaller chains and hooks), that will be slipped into a dump body and used for ice control and covering road oils. The unit will be hydraulically operated using the trucks’ existing PTO driven pump and variable flow control valves. The installation will be performed by State personnel. All sharp edges shall be ground smooth and all sharp corners rounded to prevent injury to others; The hopper shall have a minimum level capacity of Five (5) cubic yards. • The sides, ends and sills shall be unitized fully welded fabrication (side extensions not allowed) using minimum 10 gauge Stainless Steel (A certificate of compliance will be required from the successful vendor). • Bottoms of sills shall be formed outward to facilitate cleaning. • The front wall shall be sloped to eliminate bridging of material and the rear wall to be 90’ degree from the floor (not sloped). • Top of sides and ends shall be channel formed with welded mitered corners. • Each side shall be supported by at least four (4) ea. gussets formed from 7 gauge 304 stainless. Gussets to be stitch welded and staggered with a minimum of 4ʺ+/-1” overlapping beads on each side. • Four (4) ea. heavy duty stainless steel lifting eyes, rings or hooks allowing a min 2” opening to accommodate lifting hook with a safety latch shall be located on front and rear ends of body to provide proper balance for lifting the hopper from the dump body. • A heavy duty, full width fitted rubber strip shall be attached to front of sander to reduce salt from spilling out by the conveyor chain. • Hopper sill shall be supported on five (5) ea. 3” W X 2” deep maximum, 5/16” thick stainless steel cross channels at base. • Two (2) ea. 3” wide X 2” deep maximum, 5/16” thick by 104” long 304 stainless steel channels (or 304 stainless steel structural 3”X 5/16” channel) below the cross channels running front to rear with a 2” radius at front and shall be shipped loose for State personnel to locate. • Rear discharge chute area of body sill shall be double thickness stainless, fish plated and fully welded at a minimum of 36” from end of sill and further braced for strength. • The discharge gate shall be 304 stainless, at least 7 ga. with an added brace to resist bending and fully adjustable through a heavy duty curbside jack screw type adjustment which shall be a Model #T2103 Manufactured by Canimex or approved equal. • Position of the gate shall be calibrated.
