ISSUE/BACKGROUND:
body
Currently the Carrollton Wheel Press is currently out of service and needs repairs and upgrades.

DISCUSSION:
The Carrollton Wheel Press, which is used to press wheels onto axles and bearings into streetcar motors, is currently broken. Due to the age of the machine current parts are not available and the machine must be updated to complete repairs. These repairs/upgrades will extend the life of the machine by 10 years and will allow the Rail Maintenance Dept to complete maintenance on our streetcar fleet. The lead time on these repairs/updates is 4-6 months which has the potential to negatively affect our streetcar availability if not immediately addressed.
The repairs/upgrades will consist of an Complete Electrical Upgrade for COMAC Wheel Press Serial No. 221407 including New Main Control Panel complete with up-to-date electrical components, New PLC Control System, New Wheel and Bearing Chart Recorder System with Bar Code Readers and Color Printer, 15 inch wide-view Operator Interface HMI Touchscreen mounted in New Pedestal, installation of modern up-to-date Electronic Proportional Hydraulic control valves, Installation of New Digital Pressure Switches and Analog Transducers. Replacement of all original Hydraulic lines, replacement of Main Ram Chevron Packings, and replacement of Hydraulic Reservoir oil. Redesign of Elevator Armature Cradle Support Attachment for better Stability when pressing out armature shafts, Redesign of Original furnished Bearing Puller Adapter to prevent shattering during use, and Redesign of the Spreader Bar system used with the Overhead Crane to Load Wheelsets into press while keeping Wheelset Level. Additionally included with be the tooling necessary to mount your Canal Streetcar Wheels.
FINANCIAL IMPACT:
Funding is available in the amount of One hundred ninety-eight thousand and six hundred dollars ($198,600.00) through grant LA2023-001 12.42.06-12.44.20
NEXT STEPS:
When approved to proceed, the team will execute a contract and issue a purchase order and notify Contemporary Machinery & Engineering Services INC. to proceed.
