Specifications include, but are not limited to: The contractor shall furnish all equipment and labor required for a complete belt conveyor system as shown on the Drawings and specified herein. 2.1 CONVEYOR EQUIPMENT A. The conveyor equipment as supplied by Serpentix Conveyor Corporation or preapproved equal and shall consist of conveyor belt pans, tracks and supports, take-up and drive stations. The centerline length of the conveyor shall be 53’-4 5/16” and have 26-inch-wide belt pans and shall travel at 22 FPM. Loading onto the conveyor shall be distributed evenly and shall not exceed a design capacity rated at 8 wet tons per hour. The conveyor shall have a watertight modular conveying surface with a 20-degree troughed cross section at the outside of the belt width. Each modular conveying section shall have a convolution that permits the assembled belt to make continuous vertical, horizontal and helical turns that will flatten out as it goes over the drive station and allows for continuous belt cleaning with a pre-tensioned scraper bar. The modular belt pan section shall be reinforced with non-metallic stiffeners molded into each modular belt section to achieve troughing. The conveyor will be designed in such a way that all moving parts of the system, except for the drive and tension station components will pass a single designated point along the conveying path which may be used for maintenance and/or service of the conveyor. 2.2 CONVEYOR BELT AND CHAIN A. The conveying surface will consist of individually replaceable modular belt pan sections molded of moldable plastic rubber (MPR). The belt pans shall be fastened every eight (8) inches and supported by a nylon attachment and two (2) durable enhanced, plastic guide (and wear) blocks bolted to a case-hardened alloy steel chain. The chain shall have a minimum breaking strength of 35,000 pounds. Each modular belt pan section will have a cleat-like convolution at least 1-1/2 inches high, permanently molded into the rubber. The closed-link alloy steel chain, with alternating horizontal and vertical links will allow for movement in two or more directions. The 4" pitch chain will be guided by the guide blocks bolted bilaterally to each vertical chain link. The belt pan attachments and guide blocks shall be shipped assembled on the chain. The chain and guide blocks will operate in a UHMWPE track consisting of a base, two sides and two top containment angles. 2.3 TRACK STRUCTURES A. The fabricated I-beam shall be the structural frame of the conveyor system. The top and bottom flanges of the I-beam will have the UHMWPE track, with bilaterally positioned angles to contain the guide blocks as they are pulled through the track system by the steel chain. The structural I-beam will be fabricated from 1/8-inch thick, 304 stainless-steel. The containment angles will be UHMWPE. The guide blocks will stabilize the belt pan surface in the event of unbalanced material loading. Track sections of required length shall be factory fabricated and ready for job-site assembly by splice bolting where indicated.
