Department of the Army Redacted Limited Source Justification for Purchases under $150,000

Purchase Request #: 0010709891, RFQ W56HZV-15-T-L056

1. Contracting Activity: The Army Contracting Command-Warren, MI (ACC-WRN) is the procuring activity for this action.

2. Description of the Supply or Service Purchased: ACC-WRN proposes to award a new Firm Fixed Price (FFP) purchase order to Koike Aronson/Ransome, Inc. of Arcade, NY on a Brand Name basis for the procurement of a large capacity, gear driven Positioner. The positioner is in support of TARDEC’s priority one programs. It is required to rotate or tilt prototype hauls and tanks and safely manipulates hauls for better weld seam accessibility by creating increased deposition rates. Weld operators can safely manipulate hauls or tanks while concentrating on welding functions. The boxed section design takes up minimal floor space and allows unrestricted movement throughout the work area. Many safety features must be incorporated into the structural, mechanical and electrical components of modern positioners to ensure safe, productive operation.

3. Dollar Amount: The estimated total purchase price is $111,300.00. The type of funds is RDT & E.

4. Authority Cited: The statutory authority permitting other than full and open competition is “Only One Responsible Source and No Other Supplies or Services Will Satisfy Agency Requirements” and 41 U.S.C. 253(c), as implemented by FAR 13.106- 1(b)(1)(i), “Soliciting from a Single Source”, pursuant to which contracting officers may solicit from one source upon determining that only one source is reasonably available based on the circumstances of the procurement.

5. Reason for Authority Cited:

TARDEC CSI group has been tasked to come up with innovative new designs for future hauls and tanks. In order to meet our current and future requirements of manufacturing these new test beds, demonstrators, hauls, tanks, etc. a safe and productive way is needed to weld these large and heavy prototypes. Based on the requirements below, Koike Aronson is the only supply that will fit the size deminsion of the labatory.

Specifically, the product must meet the following requirements:

A. Gear Driven Positioner Capacity: 16,000 pounds maximum load or greater

• Load center of gravity no more than 12 inches above the table

• Load center of gravity no more than 12 inches eccentric from the rotation center.

B. Rotation: AC Variable frequency, high frequency protected, totally enclosed brake motor, and infinitely variable over the entire range.

• .012 to 0.60 Table RPM or greater range

• 192,000 Lb In Torque or greater

• 3 HP or greater

C. Tilt: Constant speed, AC brake motor controlled by magnetic reversing starter, with limits for over-travel protection

• 336,000 Lb In Torque or greater

• 5 HP or greater

• 135 degree forward tilt or greater

D. Table: Sandwich construction table design with preloaded tapered roller bearings.

• 54 inch square table x 2-1/2” thick or larger

• four radial 1-1/16” "T" slots, for 1”-8 bolts

• Solid spindle

• 5.010 x ½” deep pilot

E. Chassis: Machine is constructed with four heavy-duty columns for manual vertical adjustment.

• Table flat height, 59-1/4” to 95-1/4”, adjustable in 6” increments

• Rotation centerline height 50-1/4” to 86-1/4”, adjustable in 6” increments

• 2,000 Amp ground current conduction through chassis mounted ground block

F. Electricals: NEMA 12 dust-tight electricals, with main power disconnect switch, tilt axis is controlled with magnetic reversing starter, rotation axis with AC Variable frequency drive. 20 foot (or greater) remote dust tight pendant with 24V controls and E-

STOP.

G. Adjustable Base Tailstock

1. Capacity: 16,000 pounds maximum load or greater

2. • Load center of gravity no more than 12 inches off the face of the tableRotation:

Freewheeling, no gears or motors.

3. Table: Sandwich table design with preloaded tapered roller bearings.

• 54 inch square table x 2-1/2” thick or greater

• four radial 1-1/16” T slots

• 8-1/2” through hole spindle

• 8.627 x 1” deep pilot

• 2,000 Amp ground current conduction through chassis mounted ground block

Koike Aronson was selected as the preferred product, based on the following:

a. Table height 59.25" TO 95.25”, 36 inches of travel, which meets our minimum requirement 36 inches of travel line in the ‘height’ direction.

--Preston Easton table height 49” to 73”, 24 inches of travel --Pandjiris table height 58” to 88”, 30 inches of travel

b. Slowest table speed, .012 RPM, with best range .588 (with max table speed at

.60 table RPM)

c. Best delivery time, under 8 weeks available

d. The second best product would be Pandjiris.

6. Market Research:

After a broad brands market research, 3 brands were found to manufacture large capacity positioners. Preston Easton, Pandjiris, and Koike Aronson. Each company was contacted and asked to present their best positioner system for total of 32,000 lbs.

solution, which would be a positioner with a 16,000 lbs. capacity and a tailstock with 16,000 lbs. combined the system would be able to ‘handle’ or rotate 32,000 lbs. Based on available information from the vendors, Koike Aronson was selected as the preferred product, based on the following:

a. Table height 59.25" TO 95.25”, 36 inches of travel, which meets our minimum requirement 36 inches of travel line in the ‘height’ direction. Preston Easton table height 49” to 73”, 24 inches of travel, and Pandjiris table height 58” to 88”, 30 inches of travel.

b. Slowest table speed, .012 RPM, with best range .588 (with max table speed at

.60 table RPM).
