Coupling devices for tractor trailers, while not detailed online, are critical components sourced from leading manufacturers for safety and reliability. Standard fifth-wheel hitches (SAE J2429 compliant) have a 2-inch kingpin connection, rated for vertical loads up to 20 tons and drawbar pulls of 80 tons. The hitch features an automatic locking mechanism with a visual engagement indicator, and a lubrication system (self-lubricating bushings) reducing maintenance. For heavy-haul applications, optional fifth wheels have a 3.5-inch kingpin, increasing vertical load capacity to 35 tons. The coupling device is mounted on a sliding subframe (adjustable 500mm fore-aft) for optimal weight distribution. Anti-rattle mechanisms (rubber buffers) reduce noise and wear, with a service life of 1 million coupling cycles. All hitches are certified to EC 1230/2009 safety standards. Contact our parts department for coupling device specifications, including weight, mounting dimensions, and compatibility with different tractor models.
