The hydraulic towing hook is intended for coupling a tractor with single-axle trailers (semi-trailers). With the help of a hydraulic hook, the tractor operator can quickly attach a semi-trailer to it without outside help, without getting off the tractor.
In semi-trailers, the center of gravity is located between the axle of the wheels and the hinge of the drawbar, which is connected to the hook of the tractor. Therefore, the mass of the single-axle trailer and the load on it is distributed among itswheels and through the drawbar to the hydraulic hook of the tractor. This additional load, transferred to the rearwheels of the tractor, significantly increases its towing weight and improves the passability and maneuverability of the unit.(//tractor-service.com)
Industry on the basis of single-axle trailersproduces fertilized spreaders, with which the tractor works in difficult road conditions: on soft ground, in autumn-spring ruts.
