Battery Supply and Integration for Lift Systems

Transit Chicago is seeking a subcontractor to supply and integrate sealed deep-cycle batteries designed to support over twenty lifting cycles per charge in mobile column lift systems. The batteries must be engineered for high durability and consistent performance under heavy industrial use, ensuring reliable operation without the need for frequent recharging. The integration process requires seamless compatibility with existing lift hardware, including proper electrical interfacing, physical mounting, and safety compliance for operational environments such as maintenance bays and fleet service facilities. The contract is structured as a subcontract, with a response deadline of July 9, 2026, and falls under the NAICS code 335911, which pertains to other electrical equipment and component manufacturing. All work is expected to be performed in support of Transit Chicago’s fleet maintenance infrastructure, with no specific location designated for performance. The solicitation remains open for submissions through the BonfireHub platform, and interested parties are expected to demonstrate proven experience in battery systems for heavy-duty lifting applications.
