Cylinders

The Maine Department of Transportation is soliciting bids for hydraulic cylinders to support fleet maintenance operations, with a due date of March 2, 2012. The procurement carries no stated set-aside or preference program beyond Maine's standard tie-breaker preference for in-state bidders or those offering Maine-manufactured goods.

Maine DOT requires 10 cylinders across three configurations: two 3.5-inch bore by 34-inch stroke double-acting cylinders with 1.5-inch rods; two 3.5-inch bore by 43-inch stroke double-acting cylinders with 1.5-inch rods; and six 3-inch bore by 30-inch stroke double-acting cylinders with 1.5-inch rods. All must be single-stage, double-acting units rated for 2,500 psi working pressure and must be completely rebuildable and compatible with existing DOT equipment. A liquid salt bath nitriding treatment of the shaft and head is required to achieve Rockwell C scale hardness of 55–60 and corrosion resistance approximately five times greater than hard chrome plating—chrome rods are explicitly not acceptable. This specification is critical for salt environment exposure during winter highway maintenance operations. All cylinders must include a minimum two-year factory full replacement warranty.

Awards will be made to the lowest responsible bidder offering best value to the State of Maine, with evaluation considering product quality, conformity to specifications, delivery dates, and overall economy. Delivery timeframes are expressly identified as an evaluation factor. Pricing must be submitted as separate unit prices for each item, delivered to destination and inclusive of all trade or quantity discounts. Transportation charges shall be prepaid and at the contractor's expense. The state reserves the right to reject any or all quotes, waive formalities, accept individual items or groups as deemed in the state's best interest, and increase or decrease quantities by up to 10 percent. Bidders may submit questions through the Solicitation Details View page, with responses appearing in that forum.
