    these axles turn automatically, following the tractor accordingly. It considerably reduces outside forces acting the wheels and hubs, reduce the wear of the tyre, and improves the manoeuvrability of the semi-trailer. The shock absorber of the axle alignment mechanism suppresses vibration and stabilises the chassis. When using a tractor semi-trailer with a two-axle chassis of which one axle is steering and three-axle chassis of which one or two axles are steering, when moving forward, the handle of the distributor controlling the hydraulic cylinder locking the front and rear axle wheels should be set to the floating position.

    4.5. Hydraulic body tipping mechanism The hydraulic body tipping mechanism raises the front of the body. It is lowered by releasing pressure in the system: the force of the weight of the body squeezes lubricant from the hydraulic cylinder. Power to the body tipping hydraulic cylinder is supplied from the hydraulic system of the tractor (Fig.

    The tractor semi-trailer is usually equipped with a pneumatic double-circuit brake system, which acts upon all the wheels. This system, which is connected to the brake system of the tractor, acts when pressing the brake pedal of the tractor. The system has a three-position brake force regulator for each axle, which is controlled automatically, depending on the weight of the load in the body.
