Hanyang HY4390

     Notes: This semi-tractor uses an 8x8 heavy-duty suspension (with single tires on the front two axles and doubles on the rear two) and all-steel construction.  The cab tilts forward for engine and transmission access, and contains seating up front for a driver and passenger; the rear contains either a bunk or seating for four more passengers.  The HY4390 is powered by a KHD BF 12L 513FC developing 525 horsepower, coupled with a ZF 16S190A manual transmission. It is not known whether this truck is still being produced, but it is still in service with the PLA.  The HY4390 is often used as a prime mover for trailers carrying ballistic missiles, operating together with the trailer as a TEL.

Hanyang HY473A

     Notes: The HY473A semi-tractor is intended primarily for the towing of medium tank transporter trailers (mostly the HY962J), though it may also tow other types of semi-trailers (and in fact, the HY472 and HY472A are civilian versions of this truck that do tow other types of trailers, and are essentially identical to the HY473A).  It uses a forward control cab that tilts for access to the engine and transmission, and which has cab seating for three up front with another four able to sit on the bunk space in the rear.  Behind the cab are two 20-ton winches to aid in loading and unloading vehicles.  The suspension is 6x6 with single sites on the front and double tires sets on the rear two axles.  The suspension is primarily designed for road travel, and has limited off-road performance. The engine is a KHD F12L 413F diesel engine developing 355 horsepower.

     The HY473A is an improved version of an earlier model, the HY473.  Most of the differences between the HY473A and the HY473 are in the transmission; the HY473 has fewer forward gears and less torque.  In addition, the fifth wheel of the HY473 is not as robust as the HY473A.  These two factors mean that the HY473 has greater towing limits than the HY473A model.  The HY473 also uses a non-turbocharged engine and has some differences in dimensions. The HY473 is no longer in production, but is still used by the PLA.

Hanyang HY480

     Notes: This is an 8x8 semi-tractor with an off-road suspension, designed for the towing of a large variety of semi-trailers.  It uses a tipper forward-control cab, with seating for the driver and a crewmember.  Behind the seats may be installed a bunk or a seat for four passengers; the bunk and the seat may be interchanged as necessary.  The engine of the HY480 is a Norinco KHD BF12L 413FC developing 500 horsepower, coupled with an 8TBF-150 8/8 14-1 manual transmission. Though possibly no longer in production (the HY480 pre-dates the HY473A, but is a later model than the HY473), it is believed to still be in service with the PLA.
