The Trailer Power Assist (TPA) is an innovative heavy transport solution designed to enhance transport efficiency and significantly reduce the carbon footprint of large-scale projects worldwide. TPA is a powered trailer system aimed at improving transport efficiency and minimizing the CO2 emissions associated with long-distance heavy transport endeavors. As an alternative to SPMTs and conventional drive units, it consists of six axle lines, with the central four being powered by a hydraulic Power Pack Unit generating 1,000 horsepower. This system delivers double the pulling force of a traditional drive unit and offers substantial enhancements in project safety and efficiency.
