General Information
Important: Before operating the Premier coupling, refer to the Premier website () for complete safety, operation, and maintenance instructions.
Trailer couplings are attached to the rear closing crossmember. The Premier trailer couplings (see Fig.) are designed for use with trailers having a maximum gross weight of 100,000 lbs (45 455 kg).
The Premier 2200 and 2400 trailer couplings are air-adjusted couplings with a rigid pintle hook. An air chamber mounted forward of the coupling operates a push rod, which pushes against a shoe inside the coupling. The shoe maintains constant pressure on the eye of the trailer drawbar when it's over the pintle hook. This takes up any slack in the trailer connection, providing smoother towing and less wear on the pintle hook. The air pressure is activated when the trailer brakes are released.
