Self-Propelled Transporter (SPT / PST)
Up to 36 t / line · ±55° mechanical linkage steering
Mechanical-linkage self-propelled transporter with ±55° steering.

Overview
The HEAVYLT SPT / PST is a self-propelled transporter using a mechanical linkage steering system with a ±55° range. Loading capacity is up to 36 t per line. It is designed to be compatible with THI, TIANJIE, FULANGJIE, HYST, HBS, Nicolas and Goldhofer modular trailers, so it slots into mixed fleets.
Where electronic steering suits the largest load-outs, the mechanical-linkage SPT/PST is a robust, low-complexity platform for yard and in-plant moves.
