Mine Roof Simulator Repair

NOTICE OF INTENT TO ISSUE AN ORDER: This is not a request for competitive proposals/quotes. The Centers for Disease Control and Prevention (CDC) hereby announces its intent to issue a sole source order to MTS Systems Corporation, 14000 Technology Drive, Eden Prairie, MN 55344 for Mine Roof Simulator Repairs.

The NAICS code for this acquisition is 811210 - Electronic and Precision Equipment Repair and Maintenance, with a size standard of $34M.

SECTION 1 - BACKGROUND: The Mine Roof Simulator is the largest press of its kind in the world. The upper and lower platens are each 20 feet by 20 feet and the machine can accommodate a specimen up to 16 feet tall. It can simultaneously apply 1500 tons of vertical force, 800 tons of horizontal force and react 800 tons of lateral force. The vertical stroke is 24 inches and the horizontal stroke is 16 inches. The lateral displacement, pitch, roll and yaw are all commanded to zero during testing. The machine was originally designed by MTS Systems in the mid-1970s and commissioned for operation in January 1981. In 2009, the original automatic control system was upgraded to a computer controlled state-of-the-art digital system. A Just-In-Case maintenance kit was also purchased that includes spare boards, modules and a Power PC motherboard for the controller. In January of 2023 the right rear (RR) horizontal actuator started to leak a significant amount of oil. This is one of the actuators with the special hydrostatic slip bearings with a reactive load capacity of 1.6 million pounds. MTS technician was contacted and recommended the replacement of the face seal Gldy ring and O-ring packing. The Gldy ring and O-ring packing was replaced in June 2023. However, significant damage was observed to the Teflon coating on the actuator face. This likely caused the Gldy and O-ring to fail. After consulting with the MTS technician, it is recommended to replace the Teflon coating on all four of the horizontal actuators.

SECTION 2 - PURPOSE/OBJECTIVE: The purpose of this acquisition is to assure that the operation of the Mine Roof Simulator Laboratory continues and that the service of MTS Systems is available as needed at the lowest possible cost. The MRS Laboratory is used to protect the safety of coal miners by measuring the structural performance roof supports and ventilation structures that are used in coal mines.

SECTION 3 – SCOPE OF WORK:

MTS will arrange shipping of the four horizontal actuators to the MTS repair facility

MTS will repair the Teflon coating on the four horizontal actuators and any other defects required for proper operation.
